inflation pressure shown on the sidewall of the
tire.
The recommended operating tire pressure is
approximately 10 psi for the rear tires and
approximately 14 psi for the front tires. 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.

remove ignition key, disconnect the spark
plug wire(s) and ground against the engine to
prevent unintended starting before removing
