Walking Mowers

Walking Green Mowers

180SL/220SL/260SL Series

You told us you wanted quicker and easier adjustments in a walk greens mower as well as easier ways to adjust height of cut and change the front roller. And that’s what you’ll find in SL-Series Walking Greens Mowers. Dual-traction rear drums powered by an external differential drive delivers even power distribution for straighter striping. A forward-mounted pivot point reduces operator influence over the cutting plane of the mower. Hand adjustment knobs allow for easy, fine adjustment of bedknife-to-reel. And speed link bar connecting the quick adjust towers, so adjustment to height of cut can be carried out from just one side of the machine.

  • Effective height of cut

    No matter the type of reel cutting unit or surface being mowed, there are two ways to measure height of cut. The first measure is called benchsetting height of cut. This height of cut is established by using a gauge bar and measuring the distance from the bottom of the rollers to the top edge of the bedknife. This serves as an initial guide for establishing the cutting height.

    However, the cutting unit may not be mowing exactly at this height. Other factors come into play, such as softness or firmness of the mowing surface, thatch, turf density, roller shape and surface area, and weight, just to name a few. More than likely, after these factors are taken into consideration, the turf is being mowed at a height less than the benchsetting height of cut. The actual cutting height is called effective height of cut.

    How is the effective height of cut measured? It can only be measured with a prism gauge, which uses a series of mirrors to visually show the horizontal profile of the turf. The prism essentially shows the turf rotated upward 90 degrees, so the actual height of cut can easily be seen.

    Understanding effective height of cut versus benchsetting height of cut is critical when evaluating a greens mower. Traditional fixed-head walk-behind greens mowers such as the 180SL, 220SL, and 260SL will almost always cut at a lower effective height of cut compared to recent floating-head walk-behind greens mowers.

    In order to establish the same effective height of cut, the fixed-head walk-behind greens mower should be set at a higher benchsetting height of cut. Why? All of the weight of the fixed-head walk-behind greens mower is distributed to the rear drum and front roller. The weight on the actual cutting head of a floating-head mower comes from the cutting unit itself, not the traction unit. Essentially, the floating-head walk-behind greens mower is similar to a one-gang triplex in that regard.

    So, isn’t a floating-head walk-behind greens mower friendlier for the turf? The answer is no. Traditional fixed-head greens mowers stay engaged in the turf, helping to minimize thatch buildup and maintain a consistent height of cut. This may result in less thatch issues over time depending on other agronomic practices. Floating-head walk-behind greens mowers tend to ride over the top of the turf due to the light weight of the cutting unit actually in contact with the turf. This non-aggressive nature may result in significant thatch accumulation over time unless other agronomic practices are implemented.

    Both types of mowers are affected by changing conditions. Both will require height-of-cut changes as conditions soften. The difference is that the 180SL, 220SL, and 260SL will always cut at a consistent height of cut due to their weight distribution and balance, whereas floating-head walk-behind greens mowers cannot make the same claim.

    For maximum contour-following capability in severe undulations, the John Deere 180SL performs exceptionally. With a narrow 18-in. (45.7 cm) frame, fixed grass catcher, and narrow overlap, the productivity of the 180SL is roughly equal to that of 21-in. (53.34 cm) floating-head walk-behind greens mowers.


  • Rear frame

    Rubber engine isolators reduce engine vibration, enhancing operator comfort and ensuring a consistent effective height of cut across the width of the machine.

    The isolators are mounted to the front and rear frame cross members, which feature a double section for increased strength and durability.

  • There are four roller options available for greens mowing:

    • A machined grooved roller with solid endcaps
    • A continuous machined grooved roller
    • Solid smooth roller
    • Hollow smooth roller

    There is an additional spiral roller option for tee, approach, and fairway mowing. The other roller options can be considered for non-greens applications as well.

    MACHINED GROOVED ROLLER WITH SOLID ENDCAPS


    Grooved roller with solid endcaps

    • This roller gives the best overall cut quality results in most greens mowing conditions.
    • The solid endcaps help provide a larger supporting surface for the cutting unit, which is important for cleanup passes.
    • This roller is machined out of solid bar stock and has a very true surface and roundness for precise, accurate, and consistent adjustments at low heights of cut.

    MACHINED GROOVED ROLLER WITH CONTINUOUS GROOVES


    Grooved roller with continuous grooves

    These machined grooved front rollers have continuous grooves throughout the entire width of the roller.

    • This roller also provides a very good cut quality, but will provide a more aggressive cut.
    • This roller is machined out of solid bar stock and has a very true surface and roundness for precise, accurate, and consistent adjustments at low heights of cut.

    SMOOTH ROLLER OPTIONS


    Smooth roller
    The smooth rollers are intended for use on greens where the superintendent does not want to cut as aggressively.

    • These rollers are generally used during seasonal or regional conditions where the greens may be wet, soft, or stressed.
    • The hollow front roller is lighter weight and may be the preferred choice in times of extreme stress. It has a similar effect to increasing the benchsetting height of cut due to its reduced weight.

    2-IN. (50.8-MM) MACHINED SPIRAL-GROOVED ROLLER

    The 2-in. (50.8-mm) diameter spiral-grooved rollers with spiral endcaps should be used only when mowing tees, collars, approaches, or fairways. This roller should not be used on greens surfaces.


  • External differential drive


    Traction roll
    The dual traction rolls for the rear drum are powered by an external differential drive. This design provides equal power to both rolls for the straightest possible tracking. The external differential drive and split drum work together to allow minimal turning efforts and excellent maneuverability when making turns and mowing cleanup passes.

    The traction drive rolls are constructed of aluminum, which offers corrosion resistance for durability and long life. The smooth roller surface on the 180SL and 220SL Mowers provide an evenly rolled appearance on greens and other mowing surfaces. The 260SL Mower features a dimpled drum for increased traction in turfs of higher heights, such as tees, collars, aprons, and approaches.

    The outside ends of the traction rolls are tapered to provide a smooth transition between the rolled and non-rolled surface areas.


  • External differential drive


    Internal view of differential
    The external differential and reel drive sprocket provide even power distribution for a consistent speed to the drive rolls and reel. An internal gear reduction for the reel drive allows a consistent frequency of clip across the entire range of engine throttle.

    The drum drive and reel drive sprockets run in a sealed oil bath, resulting in continuous, quiet performance and exceptional component life.


  • Narrow front-roller-to-rear-drum distance

    The line of SL Walk Greens Mowers features a narrow front-roller-to-rear-drum distance for easy turning, maneuverability, and cleanup-pass cutting performance. With a Greens Tender™ Conditioner (GTC) installed, this distance is 13.5 in. (342 mm).

    A narrow front-roller-to-rear-drum base increases performance in undulations, minimizing scalping opportunities and improving cut quality.

    By keeping the roller base narrow, the John Deere SL models requires very little effort to lift the front roller to make a turn. As this distance increases, turning effort becomes much more difficult, reducing operator comfort during mowing.

    Another benefit of the narrow front-to-rear base is maneuverability. By keeping the distance as short as possible, the machine becomes much easier to steer and requires little tracking effort on every pass. As this distance increases, opportunities for difficult steering and less-than-optimal tracking become much more prevalent.

    These are important considerations when comparing to a floating-head walk-behind greens mower. Some of these competitive units feature front-roller-to-rear-drum distances that are up to 2.86 in. (72.6 mm) more than the John Deere SL models. This added distance increases lifting effort during turns and makes it more difficult to keep the machines on track.

    Also important to note is the quality of cut in the cleanup pass. Cleanup passes are made in the same track every single time they are mowed. A longer machine with limited steering means the front roller drags across the turf in the cleanup pass, eventually thinning out the turf and hurting its quality. The John Deere SL models limit this impact with its narrow front-roller-to-rear-drum distance.


  • Greens Tender Conditioner

    Both the rotary brush and Greens Tender Conditioner (GTC) rotate in the opposite direction of the reel to stand grass up prior to cutting for a consistent quality of cut. This reverse rotation also does an excellent job of standing up the leaf blades just prior to being cut by the reel. A gear-driven design provides the method for counter-rotation. Competitive walking greens mowers utilize belt-drive systems, meaning the groomer rotates in the same direction as the reel.


    Rotary brush


    DT Rotary brush
    The rotary brush helps control runners and reduce grain for a truer playing surface by lifting horizontal grass blades so they can be cut by the reel.

    The GTC controls runners and reduces grain by lifting horizontal grass blades, but it also slices stolons to promote new growth.

    The rotary brush and GTC are powered by an external gear-drive attachment:

    Gear-drive design allows the GTC to be turned off or on, a unique feature belt-drive designs cannot offer.
    The gear-drive attachment adjusts the rotary brush or GTC to 1/32 in. (0.8 mm) below cut for more aggressive grooming or 7/32 in. (5.6 mm) above cut easily without tools.
    The attachment can easily be raised or lowered into or out of the working position without any tools.
    The GTC and rotary brush drive feature a quick-engagement lever allowing the operator to either engage or disengage the drive.


  • Front roller bracket

    The ability to quickly adapt to the changing conditions is what golf courses have been doing for years. The SL model walk greens mowers from John Deere gives you the ability to meet the demanding needs of any green and helps you with the changing conditions.

    The front roller bracket on the SL line gives you the ability to quickly change your front roller for the changing conditions that most greens see during the growing season. This gives you the ability to change from a grooved roller to a smooth roller with minimal effect on your bench setting and saves the time for the golf course technician.

    How this feature works is each roller bracket has two sections that are bolted together to clamp the roller in place. The top section, connected to the Speed Link™ system, does not move when you remove the roller, thus keeping the height consistent. By removing the bottom bolt on each side, the front roller can be quickly removed from the machine, saving time and money while ensuring you have the correct roller for your condition.


  • Bedknife-to-reel adjuster tower


    Height-of-cut adjuster tower
    Bedknife-to-reel adjustments on the SL Walk Greens Mowers can be made quickly and easily, saving valuable time for technicians to complete other necessary tasks.

    The bedknife-to-reel system features two adjuster towers (one for each end of the bedknife) that are easily turned by hand. Simply use a 13-mm wrench or socket to loosen the adjuster tower clamps, turn the towers counterclockwise to increase the bedknife-to-reel gap or clockwise to decrease the gap, and tighten the adjuster tower clamps. The bedknife-to-reel clearance should be adjusted to 0.001 in. (.0254 mm).

    All SL Walk Greens Mowers feature a unique adjustment to allow for easy paralleling of the rear drum to the front roller. This can easily be accomplished using a flat plate. The parallel adjustment ensures the rear drum and reel are in the same plane, optimizing a consistent height of cut and cut quality.


  • Brushes options
    There are several options for brushes that can be utilized to improve the look and health of your greens.

    Brushes will be best used when the desire is to stand the grass plant up vertical prior to cutting by the reel and to increase the appearance of the mower stripe on the green.

    The brush will not remove or slice plant material like the blades of our Greens Tender Conditioner (GTC). Therefore, the use of both attachments may be the best combination, depending on the greens and turf type.


    Out-front push brush

    The out-front push brush is the perfect option to those customers who want to brush their greens to help the grass stand up prior to cutting, while keeping the front and rear drum in the closest set-up for ground following.

    The brush can be adjusted to increase or decrease contact with the green and also the angle of the brush. This can help with the changing conditions on the green during the growing season. The brush also contains more bristles that enable the brush to make more grass stand up across the entire mowing width of the machines. When the brush is not in use, it is easily moved into a raised position to allow mowing without using the brush.


    Standard rotary brush

    The standard brush has an exclusive helix design for mounting the bristles, similar to the blades of a reel in the cutting unit. This helix pattern of the bristles creates a more consistent turf engagement across the cutting width of the reel than straight-rowed brushes. The helix design improves the ability of the brush to stand up the grass plant without having to increase brush depth, while promoting improved striping and quality. The standard brush, with fewer bristles, will be less aggressive then the dense turf (DT) brush. The standard brush is for cool-season grasses, but can also be used in warm-season turf varieties.


    Rotary DT brush


    Closeup view of Rotary DT brush

    Exclusive helix bristle-mounting design maximizes turf engagement and ability to stand the grass plant up for cutting. Benefits include improved ball roll, reduced lateral growth, and increased striping for excellent after-cut appearance.

    The (DT) brush increases the bristle count compared to the standard brush, making it more aggressive and ideal for dense-turf varieties of warm-season grasses. The helix pattern of the bristles creates a more consistent turf engagement across the cutting width of the reel than straight-rowed brushes. The helix design improves the ability of the brush to stand up the grass plant without having to increase brush depth, while promoting improved striping and consistent cut quality.

    Additionally, all rotary brushes use our gear-driven, counter-rotating drive system. The counter-rotating of the brush improves the performance of the brush by rotating the brush in the opposite direction of travel, increasing the ability of the brush to stand up grass for cutting. This system can be turned on/off as well as raised and lowered, so you can easily choose how and when to use the brush. The counter-rotating system has been used by John Deere for over 20 years and is proven to help produce championship cut quality on some of the best courses on earth.

  • High-strength steel reels

    The 180SL, 220SL, and 260SL Mowers feature a fixed-position reel for even and consistent cutting heights.

    • Bedknife-to-reel adjustment knobs provide easy adjustment, infinite range, and pinpoint accuracy for exceptional quality of cut
    • High-strength steel reel for long-wear life, reduced maintenance, and resistance to breakage
    • Machine frame for each model matches reel width for increased productivity, easy overlapping, and even striping appearance
    • A 5-in. (12.7-cm) diameter 11-blade reel for 0.195-in. (5-mm) frequency of clip
    • Eccentric adjustment for rear roller allows quick and easy adjustment of paralleling the reel to the rear drum, optimizing height-of-cut consistency

    A seven-blade reel is available for the 260SL as a factory-installed option for mowing tees at higher heights of cut.


  • 14-blade reel

    Using the 14-blade reel on greens mowers will lower the frequency of clip and also provide a clean, smooth cut. It can increase the playability of the putting surface and greens speed.

    Frequency of clip (FOC) is defined as the distance traveled between consecutive cuts. In other words, it is how far the machine moves from the time one blade passes across the bedknife until the next blade passes. The lower the frequency of clip, the less distance that is traveled until the next blade passes.

    There is a point of diminishing returns when it comes to frequency of clip. The less distance the mower travels between consecutive cuts, the more times the same grass blade is going to be impacted by the reel. Too low a frequency of clip can cause bruising of the turf – especially in the overlap from pass to pass.

    Frequency of clip is often used as a measurement of cut quality, however there are other key factors that attribute to gaining good quality of cut. The factors that lead to good cut quality are:

    • Geometry of the cutting unit
    • Sharpness of reels and bedknife
    • Proper cutting-unit setup (parallel and bedknife-to-reel clearance)
    • Height of cut (HOC) (effective versus bench HOC)
    • Bedknife selection
    • Roller selection for the turf conditions
    • Turf conditions

    The geometry of John Deere cutting units makes the optimum range for frequency of clip between 0.160 in. (4.064 mm) and 0.190 in. (4.824 mm) for walk greens mowers. This is where the technology of the PrecisionCut™ walk greens mowers excels and provides a superior cut and after-cut appearance.

  • Bedknife
    The SL Walk-Behind Greens Mowers feature a large selection of quality bedknives for mowing any area on the golf course, including greens, tees, approaches, collars, aprons, and fairways.

    The harder the steel in a bedknife, the longer it maintains an edge. However, a harder steel is also more brittle, making the bedknife more susceptible to damage. A steel that is too soft wears quickly, but is less prone to breaking.

    The John Deere bedknife line represents a strength compromise. Special alloys ensure bedknives are tough and resistant to damage over time, without sacrificing the life of the edge.

  • Grass catcher

    The grass catcher is designed to retain clippings by slowing down the air volume and routing it out of the catcher while keeping the clippings in. Molded-in grooves and bullhorn-style mounting brackets make it easy to remove and replace the catcher. The catcher is made of lightweight polyethylene material that resists corrosion and cracking, reduces vibration, and is easy to use.

    Overlap marks are molded into the top of the catcher for increased productivity and straightly mowed passes.

    The grass-catcher system on the SL Walk Greens Mowers is fixed to the same plane as the reel. This means the grass catcher follows contours exactly as the reel does, maximizing the volume of grass thrown into the catcher. It also increases productivity by reducing the amount of overlap required.

    Some competitive floating-head walk-behind greens mowers feature a grass catcher that is mounted to the traction unit frame, while allowing the reel to independently float in relationship to the catcher. In undulations, this means grass may get projected underneath the catcher on the ends of the cutting unit. As a result, more significant overlapping is required to ensure that all of the freshly cut grass gets thrown into the catcher, not underneath it. The increased overlapping required on the floating-head units makes the productivity of a 180SL roughly equal to that of a 21-in. (53.34 cm) floating-head greens mower.

    The SLWalk Greens Mowers also feature a large-capacity grass catcher for a couple of reasons. First, a consistent effective height of cut means more grass is being cut and more grass is being thrown into the catcher. Second, increased capacity limits opportunities for grass clippings to fall out of the catcher when making turns.

  • The ultimate in quick and accurate height-of-cut adjustments: The Speed Link height-of-cut adjustment system ties both sides of the front roller together, allowing technicians to make height-of-cut adjustments simply by adjusting one end of the roller.

    How does this innovative system accomplish a one-point height-of-cut adjustment? It all starts with the worm gear drives in the front-roller castings. The worm gear system rotates via hex bolts on the side of the rear-roller castings, adjusting the roller up and down. Simply turn the gears by turning the hex adjuster on the side of the casting. Each full turn represents an adjustment of 0.001 in. (0.0254 mm). A diagram on the side of the casting tells which direction to turn the hex bolts to raise or lower the cutting height.

    But that’s not all. The true secret to the system is the connecting rod that ties the worm gear systems for the roller tower together. With the connecting rod in place, turning the height-of-cut adjuster on one side automatically turns the other side by the exact same amount. This allows for adjusting the height of cut from one end of the roller, making adjustments not only quick, but with stunning precision.

    The Speed Link connecting rod is also spring loaded, so it can be easily removed should both towers need to be adjusted independently. Once the roller is paralleled to the front roller when the cutting unit is initially set up, the Speed Link system takes over and moves each side of the roller by the same amount for a quick one-point height-of-cut adjustment.

    The preferred way to adjust the cutting unit is with a variable-speed electric or air drill with a 16-mm socket attached. A drill makes the adjustment even easier by rotating the tower quickly, making height-of-cut changes a breeze. And the connecting rod makes ensures the other side turns just as fast and just as accurately.

    NOTE: Electric or pneumatic impact tools cannot be used to make the height-of-cut adjustment.


  • Engine gear reduction

    The SL Walk-Behind Greens Mowers come standard with an engine gear reduction in the external differential drive. This mechanism automatically compensates the reel speed across the full-throttle range.

    For a three-year-experienced operator who is comfortable mowing at a faster speed and a newer operator who operates at a slower speed, the frequency of clip between the operators is exactly the same. This is a function of the gear reduction. The faster the throttle speed, the faster the reel speed. And the slower the throttle, the slower the reel speed.

    There is nothing the technician, operator, or superintendent needs to do to make this happen; it is an automatic system. Superintendents can feel confident that no matter if the operator is experienced or relatively new, the cut quality between the two will be the same.


  • Reel-bearing grease point


    Roller-bearing grease point
    Golf courses present some of the toughest conditions for a machine to operate in. The golf course environment presents several challenges, including fertilizers, pesticides, herbicides, and irrigation, to name a few. Each application presents opportunities to damage important reel bearings and roller bearings, drastically shortening the life of these components.

    Some competitive machines include sealed bearings as a feature. However, it is important to note that when a machine is washed with cool water after it has been operated, the bearings are naturally hot. When cold water is applied to a hot bearing, the water is sucked into the bearing, immediately introducing contaminants that will shorten the bearing life. With a sealed bearing, there is no way to purge these contaminants out of the bearing.

    As a result of the operating conditions, the John Deere SL models offer greasable reel and roller bearings only, no sealed bearings. After using and cleaning the machine, simply grease the bearings to purge the unwanted contaminants. This greatly increases the life of the reel and roller bearings.

220 E-Cut Hybrid Series

A true contour-following cutting head walking greens mower.

With a full-contouring 22 in (58.8 cm) QA5 cutting unit that freely moves to follow curves, the 220 E-Cut Hybrid makes the cleanup cut as easy as mowing the rest of the green. And that’s not the only way it keeps your crew ahead. The new Quick Adjust reel means height of cut can be set in seconds. A simple dial changes the frequency of clip, so you can tailor greens speed. And backlapping is such a cinch with its integrated electric motor, you can easily do it every day.


  • Ball-joint mounting system

    The primary purpose of walk greens mowers with independent cutting units is to follow contours. It is in this area the 180 E-Cut™ and 220 E-Cut Hybrid Walk Greens Mowers truly excel.

    Ball-joint mounting system

    It all starts with the ball-joint mounting system that attaches the cutting unit to the traction drive system. Similar to the PrecisionCut™, E-Cut hybrid riding greens mowers, and fairway mowers with Quick-Adjust 5 (QA5) cutting units, the ball-mounting system allows the cutting unit to rotate in any direction.

    The cutting unit not only moves fore and aft, and laterally side-to-side, it also steers in turns, which translates to a much more turf-friendly premium cut in cleanup passes around the perimeter of the green.

    Due to the ball-joint design, and also the fact that the wiring harness is the only connection to the reel drive system, the cutting unit has virtually no mechanical linkage to restrict movement of the cutting unit in the toughest of undulations.

    It is basically a one-gang triplex, and many are familiar with how well the PrecisionCut and E-Cut hybrid riding greens mowers follow contours, especially in the cleanup passes.

    For maintenance, the reel can be removed by simply removing a pin, and the electric motor itself features a quick-attach design by simply loosening two 15-mm bolts, turning the motor slightly, and pulling the motor off of the cutting unit.


    Cutting unit limit chains

    Control contour following

    Limit chains on each side of the cutting unit control how much the cutting unit contours while mowing, while also controlling the amount of rear-roller drop when the unit is lifted for turns.

    The initial setting of the chain is exactly the same as the 2500B PrecisionCut and 2500E E-Cut Hybrid Riding Greens Mowers. Two links should hang free, which means the chain itself is shortened to seven links. The upper chain anchor studs should be centered in their slots. This setting provides maximum contour following and maximum rear-roller drop when lifted.

    However, the majority of greens will not require maximum contour following. Turning and maneuvering are easiest when the amount of contour following is limited to the requirements of the surface being mowed.

    To limit the contour following of the cutting units, adjust the upper chain anchor studs backward in the slots to limit float and reduce the rear-roller drop. If further limitation is desired, shorten the chain to six links (three hanging free), and move the upper chain anchor studs forward in their slots.


  • 14-blade reel

    Using the QA5 14-blade cutting unit option on Greens Mowers will lower the FOC and also provide a clean, smooth cut. It can increase the playability of the putting surface and greens speed.

    FOC is defined as the distance traveled between consecutive cuts. It is how far the machine moves from the time one blade passes across the bedknife until the next blade passes. The lower the FOC, the less distance that is traveled until the next blade passes.

    There is a point of diminishing returns when it comes to FOC. The less distance the mower travels between consecutive cuts, the more times the same grass blade is going to be impacted by the reel. Too low an FOC can cause bruising of the turf — especially in the overlap from pass to pass.

    FOC is often used as a measurement of cut quality; however, there are other key factors that attribute to gaining superior quality of cut that are more critical than FOC. The factors that lead to good cut quality are:

    • Geometry of the cutting unit
    • Sharpness of reels and bedknife
    • Proper cutting-unit setup (parallel and bedknife-to-reel clearance)
    • Height of cut (HOC) (effective versus bench HOC)
    • Bedknife selection
    • Roller selection for the turf conditions
    • Turf conditions

    The geometry of John Deere cutting units makes the optimum range for FOC between 0.160 in. (4.064 mm) and 0.190 in. (4.824 mm) for Walk Greens Mowers and 0.044 in. (1.1176 mm) per 1 mph (1.6 km/h) for Riding Greens Mowers. Technology of the QA5 cutting units excel and provide a superior cut and after-cut appearance.

    The benefits of hybrid technology are numerous. The 2500E E-Cut™ Hybrid Riding Greens Mowers and E-Cut Hybrid fairway mowers are proof of that.

    So why not move that same technology to the walk-behind greens mowers? With the 180 E-Cut and 220 E-Cut Hybrid Walk Greens Mowers, hybrid technology is now at your disposal on even the most undulating of greens.

    In the case of walk greens mowers, hybrid technology provides more benefits than just noise reduction, fuel savings, and the elimination of any hydraulic leak points. With the 180 E-Cut and 220 E-Cut Hybrid Walk Greens Mower platform, the hybrid technology also allows a truly independent cutting unit that quickly reacts to contours, not only allowing the cutting unit to pivot laterally and fore-aft, but also to turn side to side for mowing cleanup passes.

    Because of the hybrid technology in the 180 E-Cut and 220 E-Cut Hybrid, the only link between the cutting unit and the traction unit for turning the reels off and on is the wiring harness. The wiring harness can easily move in any direction the cutting unit needs to go. There are no hard linkages in the reel-drive system to limit the cutting unit’s ability to follow contours.

    In addition, the electric drive system makes it easy to backlap by simply flipping a switch. No need for a special backlapping tool to spin the reel in reverse. It is all on board the 180 E-Cut and 220 E-Cut Hybrid as base equipment.

    Frequency of clip is also adjustable by a dial behind the handlebar cover.

    The system is powered by a Honda® engine, which turns an electric motor that is used as a generator. In between this motor and the electric reel-drive motor is the reel controller itself.

    Similar to the controllers used on the 2500E E-Cut Hybrid Greens Mowers and E-Cut Hybrid fairway mowers, the controller takes the power from the generator and controls the reel speed. This particular controller monitors engine rpm and controls reel speed to precisely match the frequency of clip that has been set.

    The electric reel-drive motor itself is the same one used on the 2500E E-Cut Hybrid Riding Greens Mowers and E-Cut fairway mowers – proven technology with proven results.

  • Backlapping switch

    A significant benefit to the electric reel-drive system is that it is very simple to change the direction of the motor, which allows the cutting unit to spin either forward for mowing or backward for backlapping.

    The 180 E-Cut™ and 220 E-Cut Hybrid Walk Greens Mowers can be backlapped without needing any external devices to drive the reel backward. It can do it all by itself with a simple toggle switch located on the rear left-hand side of the machine.

    To backlap, simply set the park brake, start the engine, toggle the mow or backlap switch to backlap, and turn on the power take-off (PTO) by toggling the PTO rocker switch on the front of the handlebar cover. The reel controller automatically sets the optimum backlapping speed; no special tools or rotary dials are needed to adjust the speed.

    This onboard backlapping saves a lot of time and money, while keeping reels in top shape for a premium quality of cut.


  • Frequency of clip dial

    The buzz in the industry is all about frequency of clip. But what exactly is it? Frequency of clip is defined as the distance traveled between consecutive cuts. In other words, it is how far the machine moves from the time one blade passes across the bedknife until the next blade passes. The lower the frequency of clip, the less distance that is traveled until the next blade passes.

    Some will say that the lower the frequency of clip the better the cut quality, but that is a misconception as the key factors of cut quality are the following:

    • Geometry of the cutting unit
    • Sharpness of reels and bedknife
    • Proper cutting unit set up (parallel and bedknife to reel)
    • Height of cut
    • Bedknife selection
    • Roller selection for the turf conditions
    • Turf conditions

    There is a point of diminishing returns when it comes to frequency of clip. The less distance the mower travels between consecutive cuts, the more times the same grass blade is going to be impacted by the reel, which leads to bruising of the turf – especially in the overlap from pass to pass.

    Optimum frequency of clip

    So, what is the optimum frequency of clip? It all depends on conditions. And the 180 E-Cut™ and 220 E-Cut Hybrid Walk Greens Mowers give the ability to establish a frequency of clip that is appropriate for individual conditions.

    The adjustment is a rotary dial located behind the handlebars. The system comes with a standard locking cover that must be accessed with tools, ensuring only those trusted to make this change, such as the superintendent or technician, can do so.

    Once the frequency of clip is established, the 180 E-Cut and 220 E-Cut Hybrid Walk Greens Mowers mow at that frequency of clip, no matter the traction speed of the machine.

    It does this by monitoring the engine rpm. As the throttle is decreased, the controller slows down the reel motor to match the new speed of the traction system, maintaining a constant frequency of clip. As the throttle is increased, the controller speeds up the reel motor to maintain the frequency of clip.

    Similar to the SL Series Walk Greens Mowers, this system keeps frequency of clip the same from operator to operator. This means no cut quality difference between more experienced operators mowing at a faster ground speed and less experienced operators mowing at a slower ground speed.


  • Diagnostic light


    Service ADVISOR™ location

    For quick and easy troubleshooting should an issue arise, a diagnostic light is located on top of the handlebar cover. If the electrical system sees a problem, a diagnostic code flashes through the indicator light. The code is repeated until the power take-off (PTO) switch is cycled off and on again, or the engine is shut off and turned on again.

    When a code is discovered, consult the technical manual for additional troubleshooting information. If a continuing condition exists, the diagnostic code displays again when the engine is started, until the original condition is corrected.

    The controller is also configured to store any code that has been displayed, so dealers can see a detailed history of the unit to aid in additional troubleshooting. The information is accessible by dealer technicians only using Service ADVISOR.


  • Traction drum

    The dual traction rolls for the rear drum are powered by an external differential drive. This design provides equal power to both rolls for the straightest possible tracking. The external differential drive and split drum work together to allow minimal turning efforts and excellent maneuverability when making turns and mowing cleanup passes.

    The traction-drive rolls are constructed of aluminum, which offers corrosion resistance for durability and a long life. The smooth roller surface on the 180 E-Cut™ and 220 E-Cut Hybrid Walk Greens Mowers provide an evenly-rolled appearance on greens and other mowing surfaces.

    The outside ends of the traction rolls are tapered to provide a smooth transition between the rolled and non-rolled surface areas.


  • Grass-catcher

    The direct-mounting grass catcher is designed to retain clippings by slowing down the air volume and routing it out of the catcher while keeping the clippings in. Molded-in grooves and mounting brackets make it easy to remove and replace the catcher. The catcher is made of lightweight polyethylene material that resists corrosion and cracking, reduces vibration, and is easy to use.

    Overlap marks for lining up to previous pass are molded into the top of the catcher for increased productivity and straightly mowed passes.

    The direct-mounting design grass-catcher system is fixed to the same plane as the reel. This means the grass catcher follows contours exactly as the reel does, maximizing the volume of grass thrown into the catcher. It also increases operator productivity by the easy removal and installation of the grass catcher.


  • Grooved disc roller

    The grooved disc roller can be used with 55.9-cm (22-in.) Quick-Adjust 5 (QA5) cutting units, in combination with the GTC and FTC, to provide additional roller options for fairway, tees, and approach areas.

    The increased diameter improves the durability over smaller rollers and it features hardened discs for improved wear which retains spring tension for reduced maintenance, making it an ideal roller for fairway, tee, and approach mowing.
