Operating Instructions

NOTE: To begin motion the operator must be in the seat and the brake disengaged before the levers can be moved from the neutral slots or the engine will kill.

By moving the levers an equal amount forward or back the mower will move in a straight line in that direction.

Movement of the right lever forward will cause the right wheel to rotate in a forward direction. Movement of the left lever forward will cause the left wheel to rotate in a forward direction. To stop forward travel pull levers back into the neutral position.

To turn right while moving in a forward direction pull the right lever back towards the neutral position, this will slow the right wheel and cause the mower to turn in that direction.

To turn left while moving in forward direction pull the left lever back towards the neutral position, this will slow the left wheel and cause the mower to turn in that direction.

To zero turn pull one lever back beyond neutral while holding the other slightly ahead of neutral. NOTE: The direction of the zero turn will be determined by which lever is pulled back beyond neutral. Thus, left lever back, left turn and opposite for right turn. Use caution when using this maneuver unit can spin very rapidly if one lever is positioned too much ahead of the other.
