WARNING: The fluid for your transmission has been spe- cially formulated to ensure the safe and proper opera- tion of your tractor. When changing the transmission fluid replace it with Cub Cadet Drive System Fluid Plus ONLY. Failure to use Cub Cadet Drive System Fluid Plus may result in a fail- ure of the drive system which could result in property dam- age or personal injury. Do not use any other fluid
See to the Maintenance Chart for the frequency of service and the Specifi- cations Chart for the quantity required.
NOTE: Do not reuse the transmission oil. Contaminated transmission oil can damage the hydro transmission.
Please dispose of used oil at appropriate recycling centers.
•Place the tractor on a level surface and engage the parking brake. Stop the tractor’s engine and remove the ignition key.
•Remove any center attachments.
