4.3 SAFETY INTERLOCK SYSTEM

The mower is equipped with a safety interlock system
intended to protect the operator and others from injury.
This is accomplished by preventing the engine from
starting unless the deck drive is disengaged, the parking
brake is engaged, the steering control levers are in
the neutral position and the operator is in the operator
position. The interlock system shuts off the engine if the
operator leaves the operator platform with the steering
control levers not in the neutral position and/or the cutter
blades engaged and the parking brake not engaged.
