screws. The cutting unit belt covers for domestic (North America) Groundsmaster
series cutting units do not require any tools for removal or installation. Ensure
that tool-less belt covers are fully seated in the retainers before returning the

The cutting unit Operator's Manual provides information regarding the

accessories for the cutting unit on your machine. Refer to the cutting unit
Operator's Manual for additional information when servicing the cutting unit.
The blades of the cutting deck must come to a complete stop in approximately
five (5) seconds after the PTO switch is disengaged. To verify the blade stopping
time:
1. Lower the cutting unit onto a clean section of turf or hard surface to avoid
dust and debris.
2. Remove one of the rotary cutting unit belt covers, or the flail cutting unit
drive belt cover.
3. Engage and then disengage the PTO switch while observing the exposed
spindle or shaft pulley. Repeat this step and record the time it takes for the
pulley to come to a complete stop.
4. If the stopping time is greater than seven seconds, the PTO clutch may need
adjustment; refer to
