Check / Fill Transmission Oil Level

This unit is equipped with two transmission oil tanks. One
transmission oil tank only supplies oil to one transmission.
The level of oil in both transmission tanks must be checked,
and if necessary, filled.
Oil Type: 20W-50 conventional detergent motor oil.
1. Location the transmission oil tanks (A, Figure 21).

2. Check the oil level when the unit is cold. The oil should be
up to the "FULL COLD" mark (B). If the oil is below this
level, proceed to step #3.
3. Before removing the tank caps (C), make sure the area
around the tank cap and fill neck of the tank is free of
dust, dirt, or other debris. Remove the tank cap.
4. Add oil up to the "FULL COLD" mark.
5. Reinstall the tank caps.
6. After adding oil to the tanks, it may be necessary to purge

Transmission Oil Filter Change

Change Interval: Every 400 Hours or Yearly (Initial hydraulic
oil and filter change after first 100 hours of operation).
It is recommended that changing the hydraulic oil and
transmission filter be a dealer only service item.

Due to the effects air has on efficiency in hydraulic drive
systems, it is critical that it be purged from the system.
These purge procedures should be implemented any time a
hydraulic system has been opened to facilitate maintenance
or any additional oil has been added to the system.
The resulting symptoms of air in the hydraulic system may be:
• Noisy operation.
• Lack of power or drive after short term operation.
• High operation temperature and excessive expansion of
Before starting, make sure the transaxles/transmissions are
at the proper oil levels. If it is not, fill to the specifications
outlined in the Check / Fill Transmission Oil Level procedure.
