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.
