Installation

Raising the Mower for Access

GrandStand Mowers Only

You can raise the front of the mower and support to access under the machine for maintenance.

Warning

The machine could fall onto someone and cause serious injury or death.

  • Always shut off the engine, engage the parking brake, and remove the key before performing any maintenance on the mower.

  • Use extreme caution when the machine is raised and supported on its back. The blades and moving parts are exposed and could cause injury.

  • Use this position only for cleaning, removing blades or baffles, and maintenance.

  1. Park the machine on a level surface, disengage the PTO, and engage the parking brake.

  2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position.

  3. Remove the battery from the machine; refer to the Operator’s Manual.

  4. Raise the mower deck to the highest position.

  5. Drain the fuel from the fuel tank; refer to Draining the Fuel Tank in the Operator’s Manual.

  6. Remove the hydraulic-tank cap and place a piece of plastic over the opening and install the cap.

    This seals the hydraulic tank and prevents fluid from leaking.
