CHANGE FWD PLANETARY HUB OIL
Park the tractor on level ground and engage the park
brake. It is recommended that oil be changed shortly
after the tractor has been operating, so that
contaminents do not settle out.
To change the oil:
1. Position the wheel so the fill/drain/level plug, 1,
is at the highest point, at 12:00.

2. Carefully loosen the plug (the planetary hubs are
not vented) and allow any air to escape. Rotate
the wheel so plug is in the lowest point. Remove
plug and drain oil completely into a suitable
container. Dispose of oil properly.
3. Rotate the wheel so the arrow and plug, 2, is
pointing straight down.
88
4. Refill the hub with new oil until it reaches the
bottom of the fill/check/level plug hole, 3, when it
is horizontal level.
5. Install the fill/drain/level plug.
6. Repeat the process on the other hub.
