Operation

Pre-Start

Fill fuel tank on level ground. For best results use only clean, fresh regular grade unleaded gasoline with an octane rating of 87 or higher.

Important: Never use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, premium gasoline, or white gas because the fuel system could be damaged.

Do Not add oil to gasoline.

Do Not overfill fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system (if equipped).

Make sure you understand the controls, their locations, their functions, and their safety requirements.

Refer to the Maintenance section and perform all the necessary inspection and maintenance steps.

Note: After starting the engine and engaging the hydro drive, if either of the drive wheels acts sluggish or will not rotate at all, stop engine and refer to the Hydraulic System Air Purge Procedure in

Maintenance.

Operating Instructions

Open the Fuel Shut-Off Valve

Rotate the valve 1/4 turn counterclockwise to turn fuel on.

Starting the Engine (Manual Start)

Note: Operator must have PTO disengaged and speed control lever in neutral position when starting the engine.

1. Lock drive levers in neutral and engage park brake.

Note: A cold weather starting kit has been added for ease of starting in either cold weather or when the unit has not been run for a period of time.

• To use cold start kit:

A. Pull split ring straight out the side of the unit, and hook the ring over the lower rear hydro control shield bolt.

B. Start engine. Refer to the following guidelines for further starting suggestions.

• To engage pump drive (disengage cold start kit):

A. Pull chain straight out from the side of the unit until the split ring can be removed from the bolt.

B. Slowly release tension on chain.

2. Pull out the choke control. Place the throttle control midway between the “Slow” and “Fast” positions.

3. Turn the key switch to the “Run” position.

4. Pull recoil rope to start engine.

5. After engine warms up, gradually push in the choke control. Do Not run warm engine with the choke in the “ON” position.

Note: Kawasaki engines generally need to be

“choked” even when warm.

Starting the Engine (Electric Start)

Note: Operator must have PTO disengaged, speed control lever in neutral position, and OPC levers depressed when starting the engine.

1. Lock drive levers in neutral and engage park brake.

2. Pull out the choke control. Place the throttle control midway between the “Slow” and “Fast” positions.

3. Turn the 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 starter cool-down period between starting attempts. Failure to follow these guidelines can burn out the starter motor.

4. After engine warms up, gradually push in the choke control. Do Not run warm engine with the choke in the “ON” position.

Note: Kawasaki engines generally need to be

“choked” even when warm.

Operation

PTO Engagement

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

1. Set throttle to “MIDWAY” position.

2. Push the PTO engagement arm forward and down to engage blades.

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

For manual start engines: The park brake must be disengaged before the PTO is engaged or the engine will kill.

Disengaging the PTO

1. Set throttle to “MIDWAY” position.

2. Pull upward and back completely on the PTO engagement arm to disengage the blades.

Stopping the Engine

1. Bring the unit to a full stop.

2. Lock drive levers in neutral.

3. Disengage the PTO.

4. Move speed control lever to neutral.

5. Engage the parking brake.

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

7. Allow the engine to run for a minimum of 15 seconds, then turn the ignition switch to the

“OFF” position to stop the engine.

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

9. Close the fuel shut-off valve when the machine will not be in use for a few days, when transporting, or when the unit is parked inside a building.

Driving the Machine

Drive Lever/Neutral Lock Latch Operation

To lock the drive levers in “neutral lock”, squeeze the drive levers to the “neutral” position (Do Not squeeze the drive levers all the way back as this will cause the drive wheels to go into full reverse direction). See

Figure 5 position 1. Place thumbs on the inner lobe

of the neutral lock latches and rotate them under the drive levers into the “neutral lock” position. See

Figure 5 position 2. Release the drive levers.

CAUTION

If the neutral lock latches are not completely engaged the drive levers could unexpectedly slip into the forward drive position. If the drive levers slip into the drive position the unit could lurch forward and cause injury or property damage.

Be sure the drive levers are past the roller and securely seated at the bottom of the neutral lock latches.

To place the drive levers in the “forward” position, slightly squeeze the drive levers while placing thumbs on the outer thumb lobe of the neutral lock latches

(or the index finger on the front lobe) and rotate them from under the drive levers. Slowly and carefully

release the drive levers. See Figure 5 position 3.

To place the drive levers in the “reverse” position, squeeze the drive levers past the neutral position. See

Figure 5 position 4.

Driving Forward

1. Release the parking brake.

2. With drive levers locked in “neutral”, shift speed control lever to desired forward speed.

3. Slowly squeeze and hold both drive levers in the neutral position and rotate both neutral lock latches from the neutral lock position to the forward position.

Note: Do Not squeeze both drive levers all the way back. This will cause the drive wheels to engage in the reverse direction.

4. To move forward in a straight line, smoothly release both drive levers to engage drive wheels.

To turn left or right, squeeze the right hand drive lever to turn right and the left hand drive lever to turn left.

To make a “zero turn”, squeeze either the left hand or the right hand drive lever back into the reverse position while the opposite drive lever is in a forward position at an equal but opposite speed.

Note: For smooth operation of this machine, avoid quick, jerky movements of the drive levers.

Move the drive levers smoothly and deliberately.

To stop, squeeze drive levers back to the “neutral” position. Move the neutral lock latches into the

“neutral lock” position and release drive levers.

Move the speed control lever to the neutral position.

Driving in Reverse

To move rearward in a straight line, squeeze drive levers into the reverse position.

To turn left or right, squeeze the right hand drive lever to turn left and the left hand drive lever to turn right.

To make a “zero turn”, squeeze either the left hand or the right hand drive lever back into the reverse position while the opposite drive lever is in a forward position at an equal but opposite speed.

Note: For smooth operation of this machine, avoid quick, jerky movements of the drive levers. Move the drive levers smoothly and deliberately.

To stop, squeeze drive levers back to the “neutral” position. Move the neutral lock latches into the

“neutral lock” position and release drive levers. Move the speed control lever to the neutral position.

Adjusting the Cutting Height

WARNING

When the two front support rod hairpins are removed from the mower deck, the weight of the tractor section may cause the front frame of the unit to rise suddenly. If the unit rises suddenly, injury may occur.

Securely hold down the front of the unit when the front support rod hairpins are removed.

The cutting height of the mower deck is adjusted from 1 1/2 to 4 1/2 inches (3.81 cm to 11.4 cm) in

1/2 inch increments.

1. Stop the machine and move the drive levers to the neutral locked position.

2. Disengage the PTO.

3. Engage the park brake.

4. Stop the engine, remove the key and wait for all moving parts to stop.

5. Install hairpin clips in the holes for the desired

cutting height. See Figure 6.

Important: To maintain correct cutting height and rake, check the following for proper adjustment.

A. The front and rear hairpins are in the same holes with the proper spacers under the hair

pins. See Figure 6.

B. The tire pressures are set as directed in Check

Tire Pressures in the Maintenance section.

C. The length of the rear deck support link assemblies average 6.89 inches (approximately

6 7/8 inches) (175.01 mm) from the center of the balljoint to the center of the farthest hole.

See Figure 7.

Note: All four pins must equally support the weight of the deck. Adjustment in the length of the rear deck support assemblies may be necessary. If one side is longer than 6.89

inches (approximately 6 7/8 inches) (175.01

mm), than the opposite side must be shorter by the same amount.

Adjusting the Anti-Scalp Rollers

It is recommended to change the anti-scalp roller position when the height of cut has changed.

1. Stop the machine and move the drive levers to the neutral lock position.

2. Disengage the PTO.

3. Engage the park brake.

4. Stop the engine, remove the key and wait for all moving parts to stop.

5. After adjusting the height of cut, adjust the anti-scalp rollers by removing the whizlock nut and spring disc washer.

6. Adjust anti-scalp rollers for Normal Operating

Conditions. Place rollers in one of the positions

shown in Figure 8. Rollers will maintain 3/4

inches (19 mm) clearance to the ground to minimize gouging and roller wear or damage.

Note: For Maximum Deck Flotation, place rollers one hole position lower. Rollers should maintain 1/4 inch (6.35 mm) clearance to ground.

Do Not adjust rollers to support the deck. Be sure roller bolts are installed with the spring disc washer between head of the nut and mounting bracket.
