Hydrostatic Transmission

Keep the area around the transmission cooling fan free of grass and debris at all times. The hydrostatic transmission is sealed at the factory and is maintenance free. The fluid level cannot be checked and on most models, cannot be changed.

If your tractor is equipped with a transmission drain plug (see Figure 23), exposed to extreme conditions (hilly terrain, towing, etc.) and you choose to change the hydrostatic fluid, do so after the tractor’s initial 50 hours of operation and every 100 hours of operation thereafter.

NOTE: Several tractor components and parts (fender, fuel tank, etc.) must be removed in order to refill the transmission after draining it.

NOTE: View shown from beneath tractor.

After draining the oil, refill the transmission with 76 oz. (to the top of the fill hole found on the transmission’s surface) with any SAE 20W50 motor oil.

Changing the Deck Belt

WARNING: Be sure to shut the engine off, remove ignition key, disconnect the spark plug wire(s) and ground against the engine to prevent unintended starting before removing the belt(s).

WARNING: Avoid the possibility of a pinching injury. Do not place your fingers on the idler spring or between the belt and a pulley while removing the belt.

All belts on your tractor are subject to wear and should be replaced if any signs of wear are present.

IMPORTANT:The V-belts found on your tractor are specially designed to engage and disengage safely. A substitute (non-OEM) V-belt can be dangerous by not disengaging completely. For a proper working machine, use factory approved belts.

To change or replace the deck belt on your tractor, proceed as follows:

•Lower the deck by moving the deck lift lever into the bottom notch on the right fender.

•Remove the belt guards by removing the self- tapping screws that fasten them to the deck.

42-inch Decks

•Remove the belt keeper rod from around the engine pulley.

•Insert a 3/8”-drive ratchet wrench (set to loosen) into the square hole found in the idler bracket on the left side of the deck’s surface. See Figure 24.
