LUBRICATION Engine oil change NOTE: Change the engine oil when the engine is warm. Refer to the engine owner's manual for the correct replacement oil and filter change recommendations. WARNING! To prevent burns, the engine should be shut off and allowed to cool slightly so the engine is still warm but the surrounding surfaces and oil are not. 1. Park on a level surface. Apply park brake. 2. Clean the dirt and debris from the area around the oil fill cap. 3. Remove the cap/dipstick. 4. Locate the drain hose at the right rear of the engine. Place an adequately sized container under the end of the drain hose and remove the oil drain plug. Transaxle (Transmission) Fluid Change This transaxle is designed with an external filter for ease of maintenance. To ensure constant fluid quality levels and longer life, an oil filter change interval of every 200 hours is recommended. The following procedure is performed with the transaxles installed in the mower and the mower on level ground. Apply the pump release valve for each transaxle and set the park brake. 1. Remove the three filter guard screws and filter guard. Clean any loose debris from around the perimeter of the filter. 2. Place an oil drain pan (12" or more diameter and 8 qt. capacity is optimal) beneath the oil filter. Remove the oil filter from the transaxle. 5. Allow the oil to fully drain from the engine. 6. Replace the drain hose plug and tighten securely. 7. Fill the engine with new oil to the bottom of the fill tube threads. Check the level with the dipstick. 8. Replace the oil fill cap securely when the oil level is FULL. 9. Refer to the Service Journal for oil checking and changing intervals. 3. After the oil has drained, wipe the filter base surface and apply a film of new oil to the gasket of the replacement filter. 4. Install the new filter by hand, turning it three-quarters to one full turn after the filter gasket contacts the filter base surface. 5. Reinstall the filter guard. Torque screws to 65 in/lbs. each. 6. Repeat steps on the opposite side. 7. Drain old oil filters of all free flowing oil prior to disposal. Place used oil in appropriate containers and dispose of it in accordance with laws in your area. 8. Remove the top port plug (see illustration) from the left side and right side of the transaxles prior to filling with oil. This will allow the transaxles to vent during oil fill. 9. Remove the cap from the transaxles' expansion tank located on the vehicle frame. 10. Fill with 20W50 motor oil until oil just appears at the bottom of each transaxles' top port (approximately 2 quarts per transaxle, 4 quarts total). Install the top port plug into each transaxle as the oil level reaches the port. 11. Install and torque the top port plugs to 180 in./lbs. 12. Continue to fill the transaxles through the expansion tank until the FULL COLD line is reached (this will take approximately 23 additional ounces). 13. Reinstall the expansion tank cap by hand. Be careful to not overtighten. 29
