Operation

Open the Fuel Shut-Off Valve

The fuel shut off valve is located behind and below the seat. Rotate the valve and align with the fuel line to open.

Starting the Engine

1.Move the motion control levers out to the neutral lock position.

2.Pull up and back on the parking brake lever to engage the parking brake.

3.Push down on the PTO switch to the “disengage” position.

Note: It is not necessary for the operator to be in the seat to start the engine.

4.Place the throttle midway between the “SLOW” and “FAST” positions.

5.On a cold engine, push the choke lever forward into the “ON” position.

On a warm engine, leave the choke in the “OFF” position.

6.Turn ignition switch to the “START” position. Release the switch as soon as the engine starts.

Important: Do Not crank the engine continuously for more than ten seconds at a time. If the engine does not start, allow a 60 second cool-down period between starting attempts. Failure to follow these guidelines can burn out the starter motor.

7.If the choke is in the “ON” position, gradually return choke to the “OFF” position as the engine warms up.

Engaging the PTO

DANGER

The rotating blades under the mower deck are dangerous. Blade contact can cause serious injury or kill you.

Do Not put hands or feet under the mower or mower deck when the blades are engaged.

DANGER

An uncovered discharge opening will allow objects to be thrown in an operator’s or bystander’s direction. Also, contact with the blade could occur. Thrown objects or blade contact can cause serious injury or death.

Never operate the mower with the discharge deflector raised, removed, or altered unless there is a grass collection system or mulch kit in place and working properly.

The PTO push-pull switch engages the cutting blades. Be sure that all persons are clear of the mower deck and discharge area before engaging PTO.

Important: Operator must be in seat before the PTO can be engaged.

1.Set the throttle midway between the “SLOW” and “FAST” positions.

2.Pull the PTO switch outward to engage the blades.

3.Place the throttle in the “FAST” position to begin mowing.

Disengaging the PTO

1.Set the throttle midway between the “SLOW” and “FAST” positions.

2.Push the PTO switch in to disengage the blades.

Stopping the Engine

6.Allow the engine to run for a minimum of 15 seconds, then turn the ignition switch to the “OFF” position to stop the engine.

7.Remove the key to prevent children or other unauthorized persons from starting engine.

8.Close the fuel shut-off valve, located behind and below the seat, when the machine will not be in use for a few days, when transporting, or when the unit is parked inside a building.
