Tires
WARNING:
Never exceed the maximum
inflation pressure shown on the sidewall of the
tire.
The recommended operating tire pressure is:
•
Approximately 10 psi for the rear tires
•
Approximately 14 psi for the front tires
IMPORTANT:
Refer to the tire sidewall for exact tire
manufacturer’s recommended or maximum psi. Do not
overinflate. Uneven tire pressure could cause the
cutting deck to mow unevenly.

Several components must be removed and
special tools (i.e. air/impact wrench) used in order to
change the tractor’s drive belt. See an authorized MTD
Service Dealer to have your drive belt replaced or
