Greasing and Lubrication

Service Interval/Specification
Check the gear lube level in the gear case after every 25
operating hours or once a year, whichever occurs first. Gear
lube changes are not required.
Gear lube type: SAE 90-140 API service GL-4 or GL-5.
Refill capacity: 32 oz. (946 ml)
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 off. Remove the key.
2. Clean the area around the lower pipe plug (Fig. 26).
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.
