Troubleshooting, Adjustment & Service

TRANSMISSION MAINTENANCE AND SERVICE

The hydrostatic transmissions are sealed units that require no maintenance other than the following.

•Keep the grass screen and transmission cooling fins clear or grass, leaves and debris.

•Keep oil level in the reservoirs (A, Figure 30) at the “FULL” line (B, Figure 30). Extra oil in the reservoir will not benefit the machine.

•If it is necessary to add oil to the reservoirs, use SAE straight 20 or 30 weight motor oil. DO NOT use a multi-grade oils. Make sure the area around the oil reservoirs is free from dust, dirt and debris before opening the reservoirs.

•Make sure the oil reservoirs caps are tight.

•Keep water, dirt and debris from entering the oil reservoirs. A small amount of a contaminant could damage the transmissions.

Changing Oil & Filters

Make sure transmissions and imme- diate surrounding areas are free from dirt and debris before changing the oil and filters. Cleanliness while per- forming this operation is extremely important.

1.Park the machine on a smooth, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key.

2.Place a drain pan under each transmission and remove the filters to drain the oil. See Figure 31.

3.Once oil has drained from transmissions, replace with new filters (P/N 21068-1), placing a light film on the seal of the filter before installing. Hand-tighten filter only.

4.Fill oil reservoirs 3/4 full with SAE straight 20 or 30 weight motor oil.

To Bleed Air From Transmissions

1.Locate the machine in a secure area, away from bystanders and preferably facing a wall. Raise the drive tires off the ground and secure with jackstands.

2.Start the engine and adjust throttle control to FULL (highest setting). See the STARTING THE ENGINE section for proper starting instructions.

3.Run engine for 15 minutes. Watch the oil level in the reservoirs. Add oil to the “FULL” line (B, Figure 30) as necessary.

4.Watch oil levels for the next few days and add oil to the reservoirs as necessary.
