Regular Maintenance
CHECK/CLEAN OIL COOLER
(23HP MODELS ONLY)
The oil cooler (G, Figure 21) should be cleaned every 25
hours, or as necessary.
CHANGE ANTIFREEZE
(LIQUID COOLED MODELS ONLY)
See Engine Manual for specific antifreeze procedures.
On Kawasaki models the antifreeze drain valve is locat-
ed on the bottom of the radiator. On Diesel the
antifreeze drain valve is located at the base of the left
hand side of the radiator.

CHECK TRANSMISSION OIL LEVEL

To check the transmission oil level observe the oil level
in the plastic tube at the rear of the unit (see Figure 25).
There should be 1" to 1-1/2" of oil in the tube. If there is
no oil in the tube add Type-F automatic transmission oil
a few ounces at a time. The transmission fill tube is
located under the seat (see Figure 26).
CHANGING TRANSMISSION FLUID
& FILTER
The transmission fluid and filter should be changed only
when performing repair work or if fluid has become dis-
colored from overheating or contamination. Perform fluid
change every 400 hours of operation if no other trans-
mission service has been done.
Replace the transmission filter whenever changing trans-
mission fluid. Make sure filter base and surrounding area
is absolutely clean before removing old filter.
1. Drain hydrostatic system by removing drain plug (B,
Figure 25). Drain fluid into a suitable container.
2. Clean the base and replace the filter using an appro-
priate filter wrench (see Figure 29 for filter location).
Reinstall the drain plug.
3. Add Type F transmission fluid through the oil fill (see
Figure 26). Capacity is 6 quarts (5.7 L).
4. Run tractor for several minutes until transmission is
warm and check fluid level in tube (A, Figure 25).
CHECK MOWER DECK
GEAR BOX OIL
To check the mower deck gear box oil:
1. Remove the plugs from the top and side of the gear
box (see Figure 27).
2. Add SAE 85W-90 oil through the top hole until oil
comes out the side fill hole. Place a shop towel
under the side opening to keep oil off the belt and
pulleys.
3. Replace the plugs and wipe up any spilled oil.
