Choke

When starting a cold engine, pull the choke control (4, Figure 1) out to close the choke plate and allow a richer fuel mixture to enter the engine. After the engine starts, push the choke control about halfway in to keep the choke pate partially closed. Push the choke control all the way in to open the choke plate for normal operation after the engine is properly warmed. A warm engine usually requires less choke to start.

Throttle Lever

Push throttle lever (5, Figure 1) forward to increase engine speed; pull back to decrease the engine speed.

Position throttle at full throttle or slightly less for optimum power and reel speed during mowing.

Traction Pedal

The traction pedal (6, Figure 1) operates the forward and reverse direction and speed of the tractor.

Moving forward: push the forward or toe of the pedal down with the ball of your foot to increase the forward speed.

Moving backward: push the heel of the pedal down with the heel of your foot to increase the reverse speed.

When the traction pedal is released, the machine will slow down and stop. The traction pedal must be in neutral position before mower will start.

Speed Control

The speed control (7, Figure 1) is meant to ease operator fatigue by holding the forward speed to a constant that is best suited for the present mowing conditions.

Adjust the hex head bolt up or down and lock it with the lock nut to limit the pedal travel.

Swing the speed control away from the traction pedal to again allow a full range of forward speeds.

Wing Mower Lift

Positioning the wing mower lift lever (8, Figure 1) will lower the side mowing units to the ground.

Pulling lever back and over center holds the mowers off the ground. Always keep mowers up when not mowing or transporting. Keep mower down during storage.

CAUTION: Do not stand on mowers when in lifted position.

Parking Brake

A convenient parking brake (9, Figure 1) is located just below the right side of the operator’s seat.

Pulling back and over center will engage the parking brake, and moving it forward, as shown, will release it.

IMPORTANT: Always make sure brake is released before moving forward, and ensure that the brake is engaged when leaving the mower. Never try to stop the forward motion of the unit with the parking brake.

Reel Drive Control

By toggling the reel drive control switch ON (10, Figure 1), an electric clutch is activated which engages power to the reels.

Pushing the switch to the OFF position disengages the clutch. This control must be in the OFF position before mower will start.

Seat Position Lever

The position of the seat is adjusted forward or backward by actuating the seat lever (11, Figure 1).

Releasing the lever will lock the seat at its present position.

Rear Mower Lift Lever

Move the rear mower lift lever (1, Figure 2) up and forward over center; the rear mower will be held off the ground.

Pull the lever up and back; the rear mower is lowered for operation or storage.

Figure 2

Free-Wheeling Valve

To permit moving the machine without starting the engine, a free-wheeling device or tow valve has been provided. The lever (1, Figure 3) is located between the engine and hydraulic pump.
