Important When adding oil to the hydraulic system,
use a funnel with a fine wire screen—200 mesh—and
ensure funnel and oil are immaculately clean. This
procedure prevents accidental contamination of the
hydraulic system.
3. Screw dipstick filler cap finger–tight onto filler neck. It
is not necessary to tighten cap with a wrench.
4. Lower the implement.
Checking the Rear Axle
The rear axle has three separate reservoirs which use SAE
80W-90 wt. gear lube. Although the axle is shipped with
lubricant from the factory, check the level before operating
the machine.
1. Position the machine on a level surface.
2. Remove check plugs from axle and make sure lubricant
is up to bottom of each hole. If level is low, remove fill
plugs and add enough lubricant to bring the level up to
the bottom of the check plug holes (Fig. 26).

3. Remove check plug. Fluid level should be up to hole in
clutch. If fluid level is low, add Mobil Fluid 424. Clutch
should be approximately 1/3 full.
4. Install check plug.
Note: Do not use engine oil (i.e. 10W30) in bidirectional
clutch. Anti-wear and extreme pressure additives will cause
undesirable clutch performance.
