If the level is at or below the "ADD" level add transmission oil into the oil fill port until the level is in the "OK" range. For best results, fill to the "FULL" mark on the dipstick as opposed to adding a specific volume of oil. Do NOT overfill. NOTE: The approved fluid is Cub Cadet Drive System Fluid Plus.

Shut the engine off, then check for leaks and re-check the oil level in the transmission case. Changing the Hydrostatic Transmission Oil CAUTION: Never overfill the transmission case. Damage or leakage may result if the oil level in the transmission case is below the "ADD" mark or over the "FULL" mark of the dipstick. 1. Place the tractor on a level surface and engage the brake pedal lock. Stop the tractor engine and remove the ignition key. 2. Clean the area around the transmission drain plug to prevent debris from entering the transmission case. Section 6 - Maintenance & Adjustments 19
