OPERATION

Running

1.Release the parking brake by moving the lever downward.

Your mower is equipped with an operator presence system. When the engine is running, any attempt by the operator to leave the seat without first setting the parking brake will shut off the engine.

2.Move the steering controls to the neutral position (N).

IMPORTANT INFORMATION

The mower deck’s gauge wheels should be evenly adjusted.

3.Select the cutting height by adjusting the cutting height pin. Release latch and lower deck to set cutting height.

WARNING!

Ensure that no one is near mower when engaging blade switch.

4.Make sure the work area is free from objects that could be thrown by the rotating blades.

5.Engage the mower deck by pulling out the blade switch.

6.Move throttle control to full throttle.

7.The machine’s speed and direction are continuously variable using the two steering controls. When both controls are in the neutral position, the machine stands still. By moving both controls an equal amount forward or backward, the machine moves in a straight line forward or backward respectively.

In order, for example, to turn right while moving forward, move the right control towards the neutral position. The rotation of the right wheel is reduced and the machine turns to the right.

Turning on the spot (zero turn) can be achieved by moving one control backward (behind the neutral position) and carefully moving the other steering control forward from its neutral position.

OPERATION

Operating on Hills

Read the Safety Instructions “Driving on Slopes” in the “Safety Instructions”.

WARNING!

Do not drive up or down hills with slopes greater than 10 degrees. Do not drive across slopes.

The slowest speed possible should be used before starting up or down hills.

Avoid stopping or changing speed on hills.

If stopping is absolutely necessary, pull drive levers into the neutral position and push

to the outside of the unit and engage the parking brake.

IMPORTANT INFORMATION

Control levers return to neutral when released. This may cause the mower to suddenly stop.

To restart movement, release the parking brake.

Pull the control levers back to the center of the mower and press forward to regain forward motion.

Make all turns slowly.

Mowing Tips

Observe and flag rocks and other fixed objects to avoid collisions.

Begin with a high cutting height and reduce it until the desired mowing result is attained. The average lawn should be cut to 2½"

(64 mm) during the cool season and over 3"

(76 mm) during the hot months. For healthier and better looking lawns, mow often after moderate growth.

For best cutting performance, grass over 6" (15 cm) in height should be mowed twice.

Make the first cut relatively high; the second to the desired height.

The mowing result will be best with a high engine speed (the blades rotate rapidly) and low speed (the rider moves slowly). If the grass is not too long and dense, the driving speed can be increased without negatively affecting the mowing result.

The finest lawns are obtained by mowing often. The lawn becomes more even and the grass clippings more evenly distributed over the mown area. The total time taken is not increased as a higher operating speed can be used without poor mowing results.

Avoid mowing wet lawns. The mowing result is poorer because the wheels sink into

the soft lawn, clumps build, and the grass clippings fasten under the cowling.

Hose the mower deck underside with water after each use. When cleaning, the mower deck shall be raised into the transport position. Make sure the mower is cooled and the engine is off.

Use compressed air to clean top surface of the deck. Avoid flooding water on top surface, engine and electrical components.

When the mulching kit is used, it is important that the mowing interval is frequent.

WARNING!

Clear the lawn of stones and other objects that can be thrown out by the blades.

Mowing pattern

WARNING!

Never drive the rider on terrain that slopes more than 10 degrees. Mow slopes up and down, never side to side. Avoid sudden directional changes.

OPERATION

Stopping the Engine

Allow the engine to idle a minute in order to attain normal operating temperature before stopping it, if it has been worked hard. Avoid idling the engine for longer periods, as there is a risk of the spark plugs fouling.

1.Disengage the mower deck by depressing the blade switch.

Disengaging the mower deck

2.Raise the mower deck by depressing the pedal forward to the transport position.

3. When the machine is standing still, activate the parking brake by pulling the lever upward.

4.Move the throttle to the minimum position (tortoise symbol). Turn the ignition key to the stop position.

5.Move the steering controls outward.

6.Remove the key when leaving the mower to prevent unauthorized use.

IMPORTANT INFORMATION

Leaving the ignition switch in any other position than “OFF” will cause the battery to be discharged and the hour meter to accumulate hours.
