MAINTENANCE
6.Engine oil: Change oil to manufacturers speci- fications. Stop engine and remove key. Drain oil when engine is warm. Loosen the 3/8” hex head on the oil drain valve at the right rear of the engine block. Be sure that the oil drain hose is on the drain and securely tight- ened. Retighten the valve after oil is drained. Remove oil filter. After oil is drained, put a light coat of clean oil on the new filter gasket before installing. Install on engine. Thoroughly clean around the cap before removing the dip- stick. Fill engine with oil, using manufacturers specs, see Engine Owners Manual. Start en- gine and idle slowly to allow the oil to recoat the interior of the engine and then inspect for leaks.

8.Belts: Check every
9.Lubrication (every 25 hours): Caster tires and front caster pivots spring loaded idler on deck. (Clean grease zerk thoroughly before greas- ing)
10.Fuel filter: 100 hours.
11.IZT’S are maintenance free and DO NOT re- quire service.
12.Tracking Plate: Grease every 50 hours. The tracking plate is welded to each drive lever. The tracking knob and tracking bolt move on this surface. Failure to grease regularly may re- sult in premature neutral and tracking
DECK BELT REPLACEMENT
First remove the belt shield from the front deck. Use a ratchet with a 9/16” socket on the spring idler bolt to relieve the spring tension on the belt. Slide the belt off of the pulleys. Jack up the rear of the unit and place jack stands under the rear deck.
Remove the nut and washer from the left hand side of the clutch tie down. (See Figure 12). Ro- tate the clutch tie down to the rear and remove the belt from the clutch. Reverse the procedures for installation of the new belt.

IZT BELT REPLACEMENT
First remove the deck belt (see Deck Belt Re- placement). Be sure the unit is still on jack stands. Use a 1/2” breaker bar on the spring idler arm and relieve the spring tension from the IZT belt. See Figure 13. Secure the spring idler out of the way being sure to keep tension on the spring so it does not come unhooked from the idler arm. Slide the belt off of the rear of the IZT pulley. Pull the belt across the top of the pulleys and over the clutch. Reverse the procedures for installation of the new belt.
