Speed Link™ height-of-cut system adjusts both sides of the roller at the same time

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.

2024 John Deere 260 SL PrecisionCut™ Optional brushes help stand the grass up for a cleaner cut and improved striping appearance

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.

2024 John Deere 260 SL PrecisionCut™ Consistent effective height of cut—A prism tells the story

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.

2024 John Deere 260 SL PrecisionCut™ Roller attaching system for quick removal and installation of the front roller for changing conditions

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.

2024 John Deere 260 SL PrecisionCut™ Narrow front-roller-to-rear-drum distance for contour following and cleanup-pass cut quality

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.

2024 John Deere 260 SL PrecisionCut™ Grass-catcher system — fixed to the plane of the reel for maximum performance in severe undulations

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.

2024 John Deere 260 SL PrecisionCut™ Integrated gear reduction yields same quality of cut regardless of operator mowing speed

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.

2024 John Deere 260 SL PrecisionCut™ Rubber isolators for reduced vibration

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.

2024 John Deere 260 SL PrecisionCut™ 2024 John Deere 260 SL PrecisionCut™ Dual traction rolls for straight tracking and excellent maneuverability

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.

2024 John Deere 260 SL PrecisionCut™ Special alloys ensure bedknives are tough and resistant

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.

2024 John Deere 260 SL PrecisionCut™ Wide range of roller options, including grooved, smooth, and spiral rollers

There are four roller options available for greens mowing:

  • A machined grooved roller with solid end caps

  • 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.

2024 John Deere 260 SL PrecisionCut™ 2024 John Deere 260 SL PrecisionCut™ Easily accessible bedknife-to-reel adjustment

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.

2024 John Deere 260 SL PrecisionCut™ 2024 John Deere 260 SL PrecisionCut™ Greaseable reel and roller bearings purge unwanted contaminants

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 greaseable 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.

2024 John Deere 260 SL PrecisionCut™ 14-blade reel lowers frequency of clip

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.
