7. Hydraulic Lift

The hydraulic lift system allows for raising and lowering implements. Ensure the hydraulic fluid level is correct before operation. Refer to the 'LUBRICATION' section for fluid specifications.

8. Engine Cooling and Air Cleaner

8.1. Engine Cooling

This tractor has an air-cooled engine. Air must circulate freely around the engine. Keep the engine, shroud, and over the deck free of grass, dirt, and other debris. Periodically clean for adequate cooling.

8.2. Dry Type Air Cleaner

The dry type air cleaner filters incoming air for combustion. Regularly inspect and clean the air cleaner element. To clean the element, remove wing nut, air cleaner cover, then remove the element. Tap it gently on a hard surface to remove loose dirt. Do not wash or use a solvent. Replace the element if damaged or excessively dirty.
