Deck Lift Spring

When mowing 2" or lower, it may be necessary to
adjust the deck lift springs. Access the springs by
tilting the seat forward. Loosen the nut to adjust
the spring tension.

Park Brake

Visually check that no damage is found on the
lever, links, or switch belonging to the park brake.

sufficient braking.

in reduced braking and can cause an accident.
