Checking for End-Play in the
Planetary Drives
Service Interval: Every 400 hours
There should be no end-play in the planetary drives/drive
wheels (i.e., the wheels should not move when you pull or
push them in a direction parallel to the axle).
1. Park the machine on a level surface, lower the cuting
units, shut off the engine, and remove the key from
the ignition switch.
2. Chock the rear wheels and raise the front of machine,
supporting the front axle/frame on jack stands.
DANGER
A machine on a jack may be unstable and slip
off of the jack, injuring anyone beneath it.
• Do not start the engine while the machine
is on a jack.
• Always remove the key from the ignition
before getting off of the machine.
• Block the tires when you are raising the
machine with a jack.
• Support the machine with jack stands.
3. Grasp 1 of the front drive wheels and push/pull
it toward and away from the machine, noting any
movement.
