MAINTENANCE
INITIAL HYDRAULIC SYSTEM CLEANING
After the first 200 hours of operation, or if the filter condition gauge shows in the red area when the oil is above
100°F drain, clean and replace the oil and filter in the following manner.
1. On a flat clean area, lower the mower to the floor, turn off the tractor, set the park brake and remove key.
2. Remove the magnetic drain plug from the bottom of the reservoir and drain the oil into a catch container. Discard
the used oil according to the regulations in your area. Clean off any particles attached to the magnetic drain plug.
Reinstall the plug using a paste-type pipe thread sealant suitable for hydraulic use.
3. Remove the suction hose and suction fittings from the tank. Remove the suction screen. (Refer to the Tank
Assembly in the parts section). Wash the suction screen in clean solvent and allow to dry thoroughly. Reinstall the
suction screen, suction fittings and suction hose using a paste-type pipe thread sealant suitable for hydraulic use.
4. Unscrew the cap from the top of the filter housing. Remove the filter element from the bowl and replace with the
new filter element provided with the new unit (P/N 02974310).
5. Fill the reservoir with a good grade of clean universal tractor hydraulic oil (P/N 02966307-5 Gal. Container).
Always add oil using a system that filters the oil prior to being added to the tank. Never assume that any oil, even
new oil in a new container, is contaminant free. To rapidly fill the tank, remove the filter cartridge from the bowl. Fill
the tank until the oil is at the top of the sight gauge. Reinstall the element and screw cap.
6. Start the tractor and check for leaks.
RESERVOIR OIL & FILTER MAINTENANCE:
Dirty oil can destroy the hydraulic system. Dirt scores valve spools and cylinder plungers and gouges metal from
pump and motor thrust plates, gears, and housings. If mower performance is lagging or system is running hotter,
the cause could be oil contamination. The oil reservoir has a filter condition gauge located on the filter housing. The
filter will show in the red arc when the oil filter needs changing or when the oil temperature is below 100
degrees F. The oil filter should be changed after every 500 hours of operation or when the gauge shows in the red
arc when the oil temperature is above 100 degrees F. When changing the filter, also replace the breather filter
element (P/N 02974319) located under the black cap. Refer to Filter Assembly in the parts section. Change the oil
and filter every 1500 hours as described in the above procedure
