Change hydraulic system filter element (Fig. 12-5) after first 50 hours of tractor operation, then replace filter and oil in reservoir every 500 hours thereafter. When changing hydraulic oil use 1/2 unit (approximately 3.5 oz.) of Lubrizol additive (Hustler P/N 027912). This additive, available from your Hustler dealer, will increase the performance life of the hydraulic system components. The system filter is located directly in front of the hydraulic reservoir.

ADJUSTMENTS Introduction Control lever in the neutral position Your Hustler ATZ was adjusted before it left the factory and was checked during predelivery setup. However, after start-up and continued use, a certain amount of break-in wear will cause some adjustments to change. Remain alert for unusual noises, they could be signaling a problem. Visually inspect the machine for any abnormal wear or damage. A good time to detect potential problems is while performing scheduled maintenance service.
internally. Secondly, the stops may be adjusted to help drive straight when the control levers are pushed forward against the stops. To keep the pumps from bottoming out internally use the following procedure: 1. To make the first adjustment the tractor engine must NOT be running. 2. Check to make sure the control levers are against the stops before the pumps are bottomed out internally.
