W ARNING

This machine is equipped with an interlock system intended to protect the operator and others from injury. This is accomplished by preventing the engine from starting unless the deck drive is disengaged, the neutral lock lever is in the neutral lock position, and the operator is in the operating position. The system shuts off the engine if the operator steps off the operator platform with the deck drive engaged or if the neutral lock lever is placed in the drive position (D) and the parking brake is applied. Never operate equipment with the interlock system disconnected or malfunctioning.

Be sure the interlock switches are functioning 10. correctly.

Fuel is flammable; handle it with care. Fill the fuel 11. tank outdoors. Never fill it indoors. Use a funnel or spout to prevent spillage. Clean up any spillage before starting the engine.

DO NOT add fuel to a running or hot engine. Allow 12. the engine to cool for several minutes before adding fuel. Never fuel indoors or inside enclosed trailers.

DO NOT operate on steep slopes. Under no circumstances should the machine be operated on slopes greater than 20 degrees. ALWAYS FOLLOW OSHA APPROVED OPERATION.

Reduce speed and exercise extreme caution on 2. slopes and in sharp turns to prevent tipping or loss of control. Be especially cautious when changing directions on slopes.

Stay two cut widths away from slopes, drop offs, 3. ditches and retaining walls.

To prevent tipping or loss of control, start and stop 4. smoothly, avoid unnecessary turns and travel at reduced speed.

When using any attachment, never direct the 5. discharge of material toward bystanders or allow anyone near the machine while in operation.

Start the engine with the operator in the operating 6. position, cutter blades are disengaged, parking brake is engaged, and the neutral lever is in neutral.

If the mower discharge ever plugs, shut off the 7. engine, remove the ignition key, and wait for all movement to stop before removing the obstruction.

Section 2

TIE DOWN POINT

The system shuts off the engine if the operator steps off the operator platform with the deck drive engaged or if the neutral lock lever is placed in the drive position (D) and the parking brake is applied. Never operate equipment with the interlock system disconnected or malfunctioning.

W ARNING

Never operate the mower with the interlock system disconnected or malfunctioning. Do not disengage or bypass any switch; injury to yourself and others or property damage could result.

DO NOT USE STARTING FLUIDS. Use of starting ﬂ uids in the air intake system may be potentially explosive or cause a “runawa y” engine condition that could result in engine damage and/or personal injury.

Be sure the fuel shutoff valve, located by the fuel 1. tank, is completely open. See Section 7.5.

GROUND TRAvEL AND STEERING4.5

- IMPORTANT -

If you are not familiar with the operation of a machine with lever steering and/or hydrostatic transmissions, the steering and ground speed operations should be learned and practiced in an open area, away from buildings, fences, or obstructions. Practice until you are comfortable with the handling of the machine before attempting to mow. Learn the operation on flat ground before operating on slopes.

- IMPORTANT -

Start practicing with a slow engine speed and slow forward travel.

Learn to feather the steering controls to obtain a smooth operating action.

Practice operating the mower until you are comfortable with the controls before proceeding to mow.

FORWARD TRAvEL

To travel forward with the mower, disengage the parking brake, place the neutral lock lever in the drive (D) position and slowly push the steering control levers forward an equal distance. The further the steering control levers are pushed forward, the greater the forward speed will be. To increase the speed, push the steering control levers forward and to decrease speed, pull the steering control levers back. See Figure 4-2.

To stop the forward travel completely, pull the steering control levers back to the neutral position.

- NOTE -

Smooth operation of the steering control levers will produce smooth mower operation. While learning the operation of the steering controls, keep the travel speed low.

REvERSE TRAvEL

CAUTION

Disengage power to the mower before backing up. Do not mow in reverse unless absolutely necessary and then only after observation of the entire area behind the mower.

CAUTION

Before backing up, observe the rear for persons and obstructions. Clear the area before backing up. Possible injury or property damage could occur.

To travel in reverse, pull both steering control handles back. Keep the travel speed low while traveling in reverse.

- NOTE -

The mower may not travel straight in reverse. Slight adjustments may need to be made using the steering controls.

To steer the mower to the left while traveling forward, pull the left steering control lever back. The further the steering control is pulled back, the quicker the mower will turn left. See Figure 4-3.

To steer the mower to the right while traveling forward, pull the right steering control lever back. The further the steering control is pulled back, the quicker the mower will turn right. See Figure 4-3.

To steer left while traveling in reverse, allow the left steering control lever to move forward. The further the control is allowed to move forward, the quicker the mower will turn left.

To steer right while traveling in reverse, allow the right steering control lever to move forward. The further the control is allowed to move forward, the quicker the mower will turn right.

To stop the reverse travel, allow the steering control levers to return to the neutral position. If the mower is to be parked, engage the parking brake and place the neutral lock lever in the neutral (N) position.

Steering ControlsFigure 4-3.

A squealing noise may be heard when engaging or disengaging the deck drive. It is caused by the electric clutch plates meshing as the mower comes up to speed. This is normal.

Section 4

To disengage the deck drive, push the switch in to 3. the disengage position.

Always operate the engine at full throttle to properly

4. maintain cutting speed. If the engine starts to lug down, reduce the forward speed and allow the engine to operate at maximum RPM.

HILLSIDE OPERATION4.7

WARNING

DO NOT operate on steep slopes. Under no circumstances should the machine be operated on slopes greater than 20 degrees. ALWAYS FOLLOW OSHA APPROvED OPERATION.

This mower has been designed for good traction and 1. stability under normal mowing conditions. However, caution must be used when traveling on slopes, especially when the grass is wet. Wet grass reduces traction and steering control.

Stay two cut widths away from slopes, drop offs, 2. ditches and retaining walls.

To prevent tipping or loss of control, do not start or 3. stop suddenly, avoid unnecessary turns and travel at reduced speed. If tires lose traction, disengage blades and proceed slowly off the slope.

Avoid sudden starts when mowing uphill. Sudden 4. starts may cause the machine to tip backwards.

Loss of traction may occur when traveling down hill. 5. Weight transfers to the front of the machine and may cause the drive wheels to slip causing loss of braking or steering.

Never back down hill.6.

AFTER OPERATION4.9

Wash the entire mower after each use. Do not 1. use high pressure spray or direct the spray onto electrical components.

- IMPORTANT -

Do not wash a hot or running engine. Cold water will damage the engine. Use compressed air to clean the engine if it is hot.

Keep the entire mower clean to inhibit serious heat

2. damage to the engine or hydraulic oil circuit.

Check the drive belts for proper alignment and any 3. signs of wear. Correct and adjust if necessary.

DANGER

To avoid injury from burns, allow the mower to cool before removing the fuel tank cap and refueling.

After the mower has cooled down, fill the fuel tank with fresh, clean fuel at the end of every day of operation. See Engine Owner's Manual for proper octane requirements.

Check the tire pressure. Adjust pressure if 5. necessary.

REMOvING CLOGGED MATERIAL4.10

DANGER

Keep tires properly inflated.7.

PARkING THE MOWER4.8

MOvING MOWER WITH ENGINE 4.11

STOPPED

To “free-wheel” or move the mower around without the engine running, place the dump valve levers in the FREEWHEEL position. Disengage the parking brake and move the mower by hand. The dump valve levers must be returned to the DRIVE position and torqued to 7-10 ft/lbs to drive the mower.

RECOMMENDATIONS FOR MOWING4.12

Do not mow with dull blades. A dull blade will tear 1. grass, resulting in poor lawn appearance and reduced mowing power.

WARNING

DO NOT operate without Discharge Chute, Mulching kit, or entire Grass Catcher properly installed.

The discharge chute must not be removed and 2. must be kept in the lowest position to deflect grass clippings and thrown objects downward. Direct the side discharge away from sidewalks or streets to minimize cleanup of clippings. When mowing close to obstacles, direct the discharge away from the obstacles to reduce the chance of property damage by thrown objects.

ADJUSTING CUTTING HEIGHT4.13

The mower deck can be adjusted from a height of 1-1/2 inch to 4-1/2 inches at 1/4-inch intervals. To adjust the cutting height:

WARNING

DO NOT adjust the cutting height with the mower blades rotating. Disengage the power to the cutter blades, put the neutral lock lever in the neutral position, apply the parking brake and then adjust cutting height.

Disengage the power to the cutter blades.

1. Pull on the cutter deck lift lever lever all the way 2.

backward until it locks in place. See Figure 4-5.

Insert the lanyard pin into the cutting height index at the desired cutting height. Pull backward on the cutter deck lift lever, push and hold the lock button See Figure 4-5. Slowly release the cutter deck lift lever. A deck height decal is located on the cutting height index as an aid in adjusting the deck to the desired height.

Cut grass when it is dry and not too tall. Do not cut

3. grass too short (cut off 1/3 or less of existing grass for best appearance). Mow frequently.

Keep mower and discharge chute clean. When mowing wet or tall grass, mow the grass twice. 5.

Raise the mower to the highest setting for the first pass and then make a second pass to the desired height.

Use a slow travel speed for trimming purposes.6. Operate the engine at full throttle for best cutting. 7.

Mowing with a lower RPM causes the mower to tear the grass. The engine is designed to be operated at full speed.

Use the alternate stripe pattern for best lawn

8. appearance. Vary the direction of the stripe each time the grass is mowed to avoid wear patterns in the grass.
