Greasing and Lubrication

Service Interval/Specification
Check the gear lubrication level in the gear case after
every 25 operating hours or once a year, whichever
occurs first. Gear lubrication changes are not
required.
Gear lube type: SAE 90-140 API service GL-4 or
GL-5.
Refill capacity: 1 qt.
Checking Gear Lube
1. Position the tractor and tiller on a level surface
and lower the attachment lift so that the tiller
tines are on the ground. Set the parking brake
and turn the ignition key to "STOP" to stop the
engine. Remove the ignition key.
2. Clean the area around the lower pipe plug
(Fig. 25).
3. Remove the pipe plug carefully because the oil
level may be above the level of the pipe plug.
4. If gear lube runs from the case when the plug is
removed, the lube in the case is sufficient. Oil
may be added as necessary.
5. Apply pipe sealant to the plug and reinstall.

Tension
1. Disengage the power take off (PTO), set the
parking brake, lower the attachment lift and turn
the ignition key to "STOP" to stop the engine.
Remove the ignition key.
2. As the drive belt wears and the tiller is raised
and lowered, the spring–loaded idler arm moves
(Fig. 26).
3. Lower the tiller and observe the spring–loaded
idler arm movement as you push on the belt. The
idler arm spring must be under tension. If it is
not under tension, replace the drive belt.
