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 speed control lever is not in the neutral position or the PTO is engaged.

Drive Levers

Located on each side of the upper handle assembly ahead of and below the handle grips.

These levers individually control the speed and direction of each drive wheel. When the speed control lever is moved out of the neutral position and the neutral lock latches are moved into the drive position,

as shown in Figure 4, and the drive levers are released, the drive wheels are engaged in the forward direction.

Squeezing the left hand and/or right hand lever causes the left hand and/or right hand drive wheel respectively to slow down, stop, or reverse, depending on how far each drive lever is “squeezed”. Squeezing the drive levers beyond the neutral position causes the drive wheels to engage in the reverse direction regardless of the position of the neutral lock latches and the speed control lever.

Neutral Lock Latches

Located on the upper handle assembly on the ends of the handle grips.

These latches allow the operator to lock the drive levers in a “neutral” position where the drive wheels are not engaged in either a forward or reverse direction.

Choke Control

Located on the front left corner of the fuel tank support.

Choke is used to aid in starting a cold engine. The choke control is pulled out to be in the “ON” position and pushed in to be in the “OFF” position. Do Not run a warm engine with choke in the “ON” position.

Throttle Control

Located on the right side of the control console.

The throttle is used to control engine speed. Moving the throttle control forward will increase engine speed and moving it to the rear will decrease engine speed. Moving the throttle forward into the detent is full position.

Speed Control Lever

Located in middle of the control console.

The speed control lever controls the maximum forward speed and is infinitely variable from neutral 0–6.2 mph (10.0 km/hr).

Park brake must be disengaged to move speed control out of neutral or engine will kill.
