• LCD indicators appear for the PTO, park brake,

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

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.

(to drive belt) which engages mower blades.

to desired position.
