the front axle dip stick (A, Figure 24), wipe it clean, and set
aside.
2. Remove drain plugs (B) and allow the main axle cavity
and two lower spindle cavities to drain completely.
Note: Drain plugs are located on front left side and right
side of tractor.
3. Once drained, reinstall the drain plugs. Add 80W-90 through
the fill holes in the lower spindle cavities and main cavity.
4. After the initial filling,oil level of all three cavities can be
checked at the dip stick (A) as oil will seep from the main
cavity to the lower ones. Reinstall dip stick.
