Lubrication

Service Interval/Specification
Check the gear lubrication oil level in the gear case every
25 operating hours and change it every 200 operating
hours or once a year, whichever occurs first.
Gear lube type: SAE 90–140 API service GL–4 or GL–5
Refill capacity: 3 pints.
Checking Gear Lube
1. Position the traction unit and plow on a level surface
and lower the attachment lift so that the plow is on the
ground.
2. Stop the engine and remove the key.
3. Check the clear glass gauge on the side of the gear
case (Fig. 12). The gear lube should be at the level of
the red dot in the center of the gauge.
4. If the gear lube level is low, remove the fill plug
(Fig. 12) and fill the case with gear lube until it is
level with the red dot in the gauge.
