Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Controls

Operator Presence Control (OPC) Levers

Located on the upper handle assembly directly above the handle grips.

When these levers are depressed, the OPC system senses that the operator is in the normal operator’s position. When the levers are released, the OPC system senses that the operator has moved from the normal operating position and will kill the engine if either the transmission shift lever is not in the neutral position or the PTO is engaged (see Figure 4 and Figure 5).
