Safety Interlock System

• LCD indicators appear for the PTO, park brake, drive levers, and operator presence in the message display on the RH control panel.

• PTO must be disengaged, brake engaged, and motion control levers out (neutral lock) to start engine. (It is not necessary for the operator to be in the seat to start the engine.)

• Operator must be in seat when PTO is engaged, brake is disengaged, or motion control levers are moved in or engine will stop.

• Engine will stop if either the left, the right, or both levers are moved from neutral lock position while brake is engaged.

Operator Controls

• Steering and Motion Control:

Note: Motion control levers are adjustable to three heights.

– Separate levers, on each side of the console, control speed and direction of travel of the respective drive wheels.

– Steering is controlled by varying the position of the levers relative to each other.

– Moving motion control levers outward (in slots) locks the drive system in neutral.
