Checking Oil Level: Check the oil level every
50 hours.
1. With the Tractor standing level and the engine
off, check the oil level with the dipstick.
2. The oil is at the correct level when the oil level
is within the mark at the lower end of the
dipstick. If low, add hydraulic oil, through the
filler hole. Do not fill beyond the mark on the
stick, as the transmission will be overfilled.
3. Install the dipstick.
Changing Oil: Change the oil every 600
hours.
1. With the oil at normal operating temperature
(Caution "Hot" oil!), drain and discard the oil
by removing the transmission drain plug.
Reinstall the plug after the oil has drained.
2. Check the oil and if necessary replace the
hydraulic oil filter.
3. Remove the filler plug, and fill with hydraulic
oil.
4. The transmission is filled to the correct level
when the oil level is within the mark at the
lower end of the dipstick. Do not fill beyond
the mark on the stick, as the transmission will
be overfilled.
5. Install the dipstick and filler plug.
IMPORTANT: The transmission, front axle and
hydraulic system operate from a common oil
sump. Special attention must be given to
keeping oil clean.
