To achieve a consistent, high quality-of-cut and a uniform after cut appearance, the machine has a clip-control feature that varies the speed of the reels with the speed of the machine, to maintain a constant clip. This feature is OFF by default; to configure it and turn it ON, refer to Setting the Clip-Control Feature

Parts needed for this procedure:

This unit complies with the ANSI B71.4-2012 and EN ISO 5395:2013 Standards when equipped with the Weight Kit, Part No. 119-7129.

Parts needed for this procedure:

If this machine will be used in the EU, affix the warning decal 133-2339 over English warning decal 133-2338.

The tires are over-inflated at the factory for shipping purposes. Reduce the pressure to the proper levels before starting the machine. Refer to Checking the Tire Pressure.

Firmly apply the brakes and drive the machine at mowing speed until the brakes are hot, as indicated by their smell. You may need to adjust the brakes after the break-in period; refer to Adjusting the Brakes.

The traction pedal (Figure 11) has 3 functions: to make the machine move forward, to move it backward, and to stop the machine. Press the top of the pedal to move forward and the bottom of the pedal to move backward or to assist in stopping when moving forward. Also, allow the pedal to move to the neutral position to stop the machine. For operator comfort, do not rest the heel of your foot on reverse when operating forward (Figure 12).

To start a cold engine, close the carburetor choke by pushing the choke lever forward (Figure 13) to the CLOSED position. After the engine starts, regulate the choke lever to keep the engine running smoothly. As soon as possible, open the choke by pulling the lever rearward to the OPEN position. A warm engine requires little or no choking.

Moving the control (Figure 13) forward during operation lowers the cutting units and starts the reels. Pull back on the control to stop the reels and raise the cutting units. During operation, you can stop the reels by pulling back on the control momentarily and releasing it. Start the reels by moving the control forward.

The functional-control lever (Figure 13) provides 2 traction selections plus a NEUTRAL position. You can shift from mow to transport or transport to mow (not to neutral) while the machine is in motion; no damage will result.

• REAR position—neutral and backlapping

• MIDDLE position—used for mowing operation

• FRONT position—used for transport operation

Insert the key into the switch (Figure 13) and turn it clockwise as far as possible to the START position to start the engine. Release the key as soon as the engine starts; the key moves to the ON position. Turn the key counterclockwise to the OFF position to shut off the engine.

Pull up on the brake lever (Figure 14) to set the parking brake. Disengage it by squeezing the release lever on the underside of the brake lever and lowering it down to the released position. Lock the parking brake any time you leave the machine.

• Fuel tank capacity: 26.6 L (7 US gallons)

• Recommended Fuel:

  • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

  • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage, which may not be covered under the warranty.

  • Do not use gasoline containing methanol.

  • Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.

  • Do not add oil to gasoline.

Important: Do not use fuel additives other than a fuel stabilizer/conditioner. Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.

1. Clean around the fuel-tank cap and remove it (Figure 21).

   

   Figure 21

   1. Fuel-tank cap

2. Add unleaded regular gasoline to the fuel tank until the level is 25 mm (1 inch) below the bottom of the filler neck.

   This space in the tank allows the fuel to expand. Do not fill the fuel tank completely full.

3. Install the cap.

   Note: You will hear a click sound when the cap is secure.

4. Wipe up any fuel that may have spilled.

Before starting the machine each day, perform the following procedures:

• Check the engine-oil level—refer to Checking the Engine Oil.

• Check the hydraulic-fluid level—refer to Checking the Hydraulic-Fluid Level.

• Check the reel-to-bedknife contact—refer to Checking the Reel-to-Bedknife Contact.

• Check the tire pressure—refer to Checking the Tire Pressure.

Refer to the engine manual supplied with the machine for oil change and maintenance procedures recommended during the break-in period.

Only 8 hours of mowing operation is required for the break-in period.

Since the first hours of operation are critical to future dependability of the machine, monitor its functions and performance closely so that minor difficulties, which could lead to major problems, are noted and can be corrected. Inspect the machine frequently during break-in for signs of oil leakage, loose fasteners, or any other malfunction.

Note: Inspect the areas beneath the mowers to be certain they are clear of debris.

The purpose of the safety-interlock system is to prevent operation of the machine where there is possible injury to the operator or damage to the machine.

The safety-interlock system prevents the engine from starting unless:

• The traction pedal is in the NEUTRAL position.

• The functional-control lever is in the NEUTRAL position.

The safety-interlock system prevents the machine from moving unless:

• The parking brake is disengaged.

• The operator is seated.

• The functional-control lever is in the MOW position or the TRANSPORT position.

The safety-interlock system prevents the reels from operating unless the functional-control lever is in the MOW position.

Perform the following system checks daily to ensure that the interlock system is operating correctly:

1. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

2. Try to press the traction pedal.

   The pedal should not press, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

3. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

4. Move the functional-control lever to the MOW position or the TRANSPORT position and try to start the engine.

   The engine should not turnover or start, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

5. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

6. Start the engine and move the functional-control lever to the MOW position or the TRANSPORT position.

   The engine should shut off, which means that the interlock system is operating correctly.

   Correct the problem if it is not operating properly.

7. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional control lever to the NEUTRAL position, and engage the parking brake.

8. Start the engine.

9. Release the parking brake, move the functional control lever to the MOW position, and rise from the seat.

   The engine should shut off, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

10. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional control lever to the NEUTRAL position, and engage the parking brake.

11. Start the engine.

12. Move the raise/lower mow control forward to lower the cutting units. The cutting units should lower but not start rotating.

    If they start rotating, the interlock system is not operating correctly; correct the problem before operating the machine.

Ensure that the cutting units are fully raised. Move the functional-control lever to the TRANSPORT position. Use the brakes to slow the machine while going down steep hills to avoid loss of control. Always approach rough areas at a reduced speed and cross severe undulations carefully. Familiarize yourself with the width of the machine. Do not attempt to pass between objects that are close together so that costly damage and down time can be prevented.

Before mowing greens, find a clear area and practice starting and stopping the machine, raising and lowering the cutting units, turning, etc.

Inspect the green for debris, remove the flag from the cup, and determine the best direction to mow. Base the direction to mow on the previous mowing direction. Always mow in an alternate pattern from the previous mowing so that the grass blades are less apt to lay down and therefore be difficult to trap between the reel blades and the bedknife.

1. Approach the green with the functional-control lever in the MOW position and the throttle at full speed.

2. Start on 1 edge of the green so that you can use the ribbon procedure of cutting.

   Note: This holds compaction to a minimum and leaves a neat, attractive pattern on the greens.

3. Actuate the raise/lower mow lever as the front edges of the grass baskets cross the outer edge of the green.

   Note: This procedure drops the cutting units to the turf and starts the reels.

   Important: The No. 1 cutting unit reel is delayed; therefore, you should practice to gain the required timing necessary to minimize the cleanup mowing operation.

4. Overlap a minimal amount with the previous cut on return passes.

   Note: To assist in maintaining a straight line across the green and keep the machine an equal distance from the edge of the previous cut, establish an imaginary sight line approximately 1.8 to 3 m (6 to 10 ft) ahead of the machine to the edge of the uncut portion of the green (Figure 22). Some find it useful to include the outer edge of the steering wheel as part of the sight line; i.e., keep the steering wheel edge aligned with a point that is always kept the same distance away from the front of the machine.

5. As the front edges of the baskets cross the edge of the green, move the raise/lower mow lever rearward and hold it until all the cutting units have risen. This stops the reels and lifts the cutting units.

   Note: It is important to time this step correctly so that you do not cut into the fringe area yet cut as much of the green as possible to minimize the amount of grass left to mow around the outer periphery.

6. To cut down on operating time and ease lineup for the next pass, momentarily turn the machine in the opposite direction, then turn it in the direction of the uncut portion; i.e., if intending to turn right, first swing slightly left, then right.

   Note: This helps to get the machine more quickly aligned for the next pass. Try to make as short of a turn as possible except during warmer weather when a wider arc minimizes the turf bruising.

   

   Figure 22

   1. Alignment strip
   2. Approximately 12.7 cm (5 inches)
   3. Cut grass on the left
   4. Keep a focal spot 2 to 3 m (6 to 10 ft) ahead of the machine.

   Note: The steering wheel does not return to its original position after you complete a turn.

   Important: Never stop the machine on a green with the cutting unit reels operating as damage to the turf may result. Stopping the machine on a wet green may leave marks or indentations from the wheels.

7. If the leak detector alarm (if equipped on your model) sounds or you notice an oil leak while cutting on a green, immediately raise the cutting units, drive directly off the green, and stop the machine in an area away from the green. Determine the cause of the leak and correct the problem.

8. Finish cutting the green by mowing the outer periphery. Be sure to change the direction of cutting from the previous mowing.

   Note: Always keep weather and turf conditions in mind and be sure to change the direction of mowing from the previous cutting.

9. When finished mowing the outer periphery, tap the raise/lower mow lever rearward to stop the reels, then drive off the green. When all the cutting units are off of the green, raise them.

   Note: This minimizes grass clumps left on the green.

10. Replace the flag.

11. Empty the grass baskets of all clippings before transporting to the next green.

    Note: Heavy wet clippings place an undue strain on the baskets and add unnecessary weight to the machine, thereby increasing the load on the engine, hydraulic system, brakes, etc.

After mowing, thoroughly wash the machine with a garden hose without a nozzle so that excessive water pressure does not contaminate and damage the seals and bearings. Do not wash a warm engine or electrical connections with water.

After cleaning, inspect the machine for possible hydraulic fluid leaks, damage or wear to hydraulic and mechanical components, and the cutting units for sharpness. Also, lubricate the brake-shaft assembly with SAE 30 oil or spray lubricant to deter corrosion and help keep the machine performing satisfactorily during the next mowing operation.

• Use care when loading or unloading the machine into a trailer or a truck.

• Use full-width ramps for loading the machine into a trailer or a truck.

• Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine.

In case of an emergency, you can tow the machine for up to 0.4 km (1/4 mile).

Important: Do not tow the machine faster than 3 to 5 km/h (2 to 3 mph) to avoid damaging the drive system. If you must move the machine more than 0.4 km (1/4 mile), transport it on a truck or trailer.

1. Locate the bypass valve on the pump and rotate it so that the slot is vertical (Figure 23).
