Greensmaster® 3300 TriFlex® Traction Unit

1. Sit on the seat, engage the parking brake, disengage the raise/lower mow control and move the functional-control lever to the NEUTRAL position.

2. Ensure that the traction pedal is in the NEUTRAL position and that you foot is off the pedal.

3. If you are starting a cold engine, move the choke to the ON position.

4. Move the throttle lever to the HALF THROTTLE position.

5. Insert and rotate the ignition key clockwise until the engine starts.

6. After the engine starts, adjust the choke to run the engine smoothly. As soon as possible, open the choke by pulling it rearward to the OFF position. A warm engine requires little or no choking.

1. Move the throttle lever to the FAST position.

2. Move the raise/lower mow control lever forward momentarily.

   The cutting units should lower and all the reels should rotate.

   Note: The function lever should be in the middle (mow) position for the reels run when lowering the cutting units

3. Move the raise/lower mow control lever rearward.

   The cutting reels should stop rotating and the cutting units should raise to the full transport position.

4. Engage the brake to keep the machine from moving, and operate the traction pedal through the forward and reverse positions.

5. Continue the above procedure for 1-2 minutes. Move the functional-control lever to the NEUTRAL position, lock the parking brake, and shut off the engine.

6. Check for fluid leaks and tighten the hydraulic fittings if any are found.

   Note: When the machine is new and the bearings and reels are tight, it is necessary to use the FAST throttle lever position for this check. A fast throttle setting may not be required after the break-in period.

   Note: If fluid leaks continue to appear, contact your Authorized Toro Distributor for assistance and, if necessary, replacement parts.

   Important: A trace of fluid on the motor or wheel seals is normal. Seals require a small amount of lubrication to perform properly.

1. Move the throttle lever to the SLOW position, pull back the raise/lower mow control, and move the functional-control lever to the NEUTRAL position.

2. Rotate the ignition key to the OFF position to shut off the engine. Remove the key from the switch to prevent accidental starting.

3. Close the fuel shut-off valve before storing the machine.

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.

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. 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.

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. 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.

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. Start the engine.

3. 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.

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. Start the engine.

3. 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.

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: There is a delay raising and lowering the center cutting unit; therefore, you should practice to gain the required timing necessary to minimize the cleanup mowing operation.

   Note: The delay raising and lowering the center cutting unit depends on hydraulic fluid temperature. Cold hydraulic fluid results in a longer delay. As the temperature increases the delay time becomes shorter.

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.

   Note: 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.

1. 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.

2. 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 the green, raise the cutting units.

   Note: This minimizes grass clumps left on the green.

3. Replace the flag.

4. 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.

• Shut off the engine before checking the oil or adding oil to the crankcase.

• Do not change the governor speed or overspeed the engine.

1. Clean the air-cleaner cover (Figure 24).

   

   Figure 24

   1. Air-cleaner cover

2. Release the locking clips and remove the air-cleaner cover.

3. Remove the wing nut securing the elements to the air-cleaner body (Figure 25).

4. If the foam element is dirty, remove it from the paper element (Figure 25). Clean it thoroughly, as follows:

   1. Wash the foam element in a solution of liquid soap and warm water. Squeeze it to remove dirt.

   2. Dry it by wrapping it in a clean rag. Squeeze the rag and foam element dry.

      Important: When drying the foam element, do not twist it; the foam may tear.

      1. Foam element
      2. Paper element

5. Check the condition of the paper element. Clean it by gently tapping it on a flat surface or replace it if needed.

6. Install the foam element, paper element, wing nut, and air-cleaner cover.

   Important: Do not operate the engine without the air-cleaner element because extreme engine wear and damage will likely result.

The engine is shipped with oil in the crankcase; however, you must check the oil level before and after starting the engine the first time.

Spark plug specification: Champion RC 14YC

Air gap specification: 0.76 mm (0.030 inch)

1. Clean the area around the spark plugs so that foreign matter cannot fall into the cylinder.

2. Pull the wires off the spark plugs and remove the plugs.

3. Check the condition of the side electrode, center electrode, and center electrode insulator to ensure that there is no damage.

   Important: Replace a cracked, fouled, dirty, or otherwise malfunctioning spark plug. Do not sand blast, scrape, or clean electrodes by using a wire brush because grit may eventually release from the plug, fall into the cylinder, and damage the engine.

4. Set the air gap between the center and side of the electrodes at 0.76 mm (0.030 inch) as shown in Figure 28.

   

   Figure 28

5. Install the spark plug and gasket seal, and tighten the plug to 23 N∙m (200 in-lb).

The in-line fuel filter is in the fuel line between the fuel tank and carburetor (Figure 29).

2. Place a drain pan under the filter, loosen the hose clamp on the carburetor side of filter, and remove the fuel line from the filter (Figure 29).

3. Loosen the other hose clamp and remove the filter (Figure 29).

4. Install the new filter with the arrow on the filter body pointing away from the fuel tank.

Inspect the fuel lines for deterioration, damage, or loose connections.

Properly maintain the battery electrolyte and keep the top of the battery clean. Store the machine in a cool place to prevent the battery from running down.

The battery cables must be tight on the terminals to provide good electrical contact.

1. Check the electrolyte level in the in the cells of the battery.

2. If needed, add distilled or demineralized water into the cell of the battery.

   Note: Only to raise the electrolyte level to the bottom of the split ring inside each cell.

3. Clean the top of the battery by washing it periodically with a brush dipped in ammonia or bicarbonate of soda solution.

4. Flush the top surface of the battery with water after cleaning it.

   Important: Do not remove the fill caps while cleaning the battery.

If corrosion occurs at the terminals, disconnect the cables, negative (-) cable first, and scrape the clamps and terminals separately. Connect the cables, positive (+) cable first, and coat the terminals with petroleum jelly.

The fuses in the electrical system are located under the seat (Figure 30).

Vary the tire pressure for all 3 wheels, depending upon your turf conditions, from a minimum of 83 to a maximum of 110 kPa (12 psi to 16 psi).

Wheel nut torque specification: 95 to 122 N∙m (70 to 90 ft-lb)

Note: To ensure even distribution, torque the wheel nuts in a X pattern.

If the machine creeps when the traction-control pedal is in the NEUTRAL position, adjust the neutral-return mechanism.

1. Ensure that the bypass valve is closed.

2. Lift the machine and support it at the frame so that 1 of the front wheels is off the floor.

   Note: If machine is equipped with a 3-Wheel Drive Kit, also raise and block rear wheel.

3. Start the engine, move the throttle to the SLOW position, and ensure that the front wheel that is off the floor is not rotating.

4. If the wheel is rotating, shut off the engine and proceed as follows:

   1. Loosen the nut securing the eccentric to the top of the hydrostat (Figure 31).

      

      Figure 31

      1. Eccentric
      2. Locknut

   2. Move the functional-control lever to the NEUTRAL position and the throttle to the SLOW position. Start the engine.

   3. Rotate the eccentric until creep does not occur in either direction. When the wheel stops rotating, tighten the nut locking the eccentric and the adjustment (Figure 31). Verify the adjustment with the throttle in the SLOW and FAST position.

      Note: If the wheel still turns when the eccentric is at the maximum adjustment, contact your authorized Toro distributor or refer to the Service Manual for further adjustment.

The mow speed is set to 3.8 mph at the factory.

The forward moving speed can be adjusted from 0 to 8 km/h (0 to 5 mph).

1. Loosen the jam nut on the trunnion bolt (Figure 33).

2. Loosen the nut securing the lock and mow brackets on the pedal pivot.

   

   Figure 33

   2. Nut
   3. Trunnion bolt

3. Rotate the trunnion bolt clockwise to reduce the mowing speed and counterclockwise to increase the mowing speed.

4. Tighten the jam nut on the trunnion bolt and the nut on the pedal pivot to lock the adjustment (Figure 33). Check the adjustment and adjust as required.

If the brake fails to hold the machine while parked, you can adjust the brakes using the bulkhead fitting near the brake drum; contact your Authorized Service Distributor or refer to the Service Manual for more information.

Note: Burnish the brakes annually; refer to Burnishing the Brakes.

Important: Regardless of the hydraulic fluid type used, any traction unit used for off-green applications, verticutting or used during ambient temperatures above 29° C (85°F) should have the Oil Cooler Kit installed; refer to Installing the Oil Cooler (optional).

Check the hydraulic lines and hoses daily for leaks, kinked lines, loose mounting supports, wear, loose fittings, weather deterioration, and chemical deterioration. Make all necessary repairs before operating.

The leak detector system is designed to assist in early detection of hydraulic-fluid-system leaks. If the fluid level in the main hydraulic reservoir is lowered by 118 to 177 ml (4 to 6 oz), the float switch in the tank will close. After a 1 second delay, the alarm sounds, alerting the operator (Figure 39). Expansion of fluid, due to normal heating during machine operation, causes the fluid to transfer into the auxiliary fluid reservoir. The fluid returns to the main tank when you turn off the ignition switch.

Note: When sharpening, setting the height-of-cut, or performing other maintenance procedures on the cutting units, store the cutting unit reel motors in the storage location on the front of the suspension arms to prevent damage to them.

Important: Do not raise the suspension to the transport position when the reel motors are in the holders in the machine frame. Damage to the motors or hoses could result.

Important: Whenever you need to tip the cutting unit, prop up the rear of the cutting unit to ensure that the nuts on the bedbar adjusting screws are not resting on the work surface (Figure 41).

Each day before operating the machine, check the reel-to-bedknife contact, regardless if the quality of cut had previously been acceptable. There must be light contact across the full length of the reel and bedknife; refer to the Cutting Unit Operator’s Manual.

To achieve a consistent, high-quality cut and a uniform, after-cut appearance, you must correctly set the reel speed control (located on the manifold block under the cover to the left of the seat). Adjust the reel speed control as follows:

1. Select the height-of-cut at which the cutting units are set.

2. Choose the desired ground speed best suited for conditions.

3. Use the table that follows to determine the reel-speed setting for your 5-, 8-, 11-, or 14-blade cutting units. (Figure 48)

   

   Figure 48

4. Adjust the reel speed by rotating the knob (Figure 49) until the indicator arrows are in line with the number you determined in step 3.

   

   Figure 49

   1. Reel-speed control

   Note: You can increase or decrease the reel speed to compensate for turf conditions.

1. Position the machine on a level surface, lower the cutting units, shut off the engine, and engage the parking brake.

2. Remove the plastic cover to the left side of the seat.

3. Make initial reel to bedknife adjustments appropriate for backlapping on all cutting units which are to be backlapped; refer to the Cutting Unit Operator’s Manual.

   Danger

   Changing the engine speed while backlapping may cause the reels to stall.

   • Never change the engine speed while backlapping.

   • Backlap only at idle engine speed.

4. Start the engine and run at low idle speed.

5. Rotate the backlap lever to the REVERSE (R) position (Figure 50).

   

   Figure 50

   1. Backlap lever—FORWARD position
   2. Backlap lever—REVERSE position

6. Rotate the reel-speed control to setting 1 (Figure 51).

   

   Figure 51

   1. Reel-speed control

7. With the functional-control lever in the NEUTRAL position, move the raise/lower mow control forward to start the backlapping operation on the designated reels.

8. Apply lapping compound with a long handle brush. Never use a short handled brush.

9. If the reels stall or become erratic while backlapping, select a higher reel speed setting until the speed stabilizes, then return the reel speed to setting 1 or to your desired speed.

10. To make an adjustment to the cutting units while backlapping, turn the reels off by moving the raise/lower mow control rearward and shut off the engine. After completing adjustments, repeat steps 4 through 8.

11. Repeat the procedure for all cutting units you want to backlap.

12. When finished, return the backlap levers to the FORWARD (F) position, replace the cover, and wash all lapping compound off of the cutting units. Adjust cutting unit reel to bedknife as needed. Move the cutting unit reel speed control to the desired mowing position.

    Important: If the backlap lever is not returned to the FORWARD (F) position after backlapping, the cutting units will not raise or function properly.

The service indicator light illuminates in the event of a fault in the machine. When this light is on, you can access the computer codes to diagnose the problem by entering diagnostic mode. In diagnostic mode, the service indicator light flashes a number of times, giving you the error code that you or your authorized Toro distributor can use to identify the problem.

Note: You cannot start the engine in diagnostic mode.
