• The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.

• Wear appropriate clothing, including eye protection; long pants; slip-resistant, substantial foot protection; and hearing protection. Tie back long hair and do not wear jewelry.

• Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.

• Never carry passengers on the machine and keep bystanders and pets away from the machine during operation.

• Operate the machine only in good visibility to avoid holes or hidden hazards.

• Avoid mowing on wet grass. Reduced traction could cause the machine to slide.

• Before you start the engine, ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position.

• Keep your hands and feet away from the cutting units. Keep clear of the discharge opening at all times.

• Look behind and down before backing up to be sure of a clear path.

• Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

• Do not mow near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge gives way.

• Stop the cutting units whenever you are not mowing.

• Stop the machine and inspect the cutting units after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.

• Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

• Disengage the drive to the cutting unit and shut off the engine before adjusting the height of cut (unless you can adjust it from the operating position).

• Never run an engine in an area where exhaust gasses are enclosed.

• Never leave a running machine unattended.

• Before leaving the operating position (including to empty the catchers or to unclog the chute), do the following:

  • Park the machine on level ground.

  • Disengage the power take-off and lower the attachments.

  • Engage the parking brake.

  • Shut off the engine and remove the key.

  • Wait for all moving parts to stop.

• Do not operate the machine when there is the risk of lightning.

• Do not use the machine as a towing vehicle.

• Use accessories, attachments, and replacement parts approved by The Toro® Company only.

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 move the traction pedal forward or backward.

   The pedal should not move, which indicates 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 indicates 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 indicates 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 indicates 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. Push forward 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—gaining 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 24). 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, pull back 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; a tear-shaped turn (Figure 23) to quickly line up for your next pass.

   

   Figure 23

   Note: Try to make as short of a turn as possible except during warmer weather when a wider arc minimizes the turf bruising.

   

   Figure 24

   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. 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.

   2. Oil filter

2. Clean the threads of the drain plug, apply PTFE sealant, and install the drain plug (Figure 29).

3. Remove the oil filter (Figure 29).

4. Apply a light coat of clean oil to the new filter gasket.

5. Screw the filter on by hand until the gasket contacts the filter adapter, then tighten it 3/4 to 1 turn further. Do not overtighten it.

6. Add oil to the crankcase; refer to Engine Oil Specification and Checking the Engine Oil.

7. Dispose of the oil filter and used oil properly.

The traction pedal comes adjusted for maximum-transport speed, but you may need to adjust it if the pedal reaches full stroke before it contacts the pedal stop, or if you want to a decrease the transport speed.

To obtain the maximum-transport speed, put the functional control lever in the TRANSPORT position and press down on the traction pedal. If the pedal contacts the stop (Figure 34) before you feel tension on the cable, perform the following adjustment procedure:

Figure 34

1. Pedal stop

1. Put the functional-control lever in the TRANSPORT position and loosen the locknut securing the pedal stop to the floor plate (Figure 34).

2. Tighten the pedal stop until it does not contact the traction pedal.

3. Continue applying a light load on the transport pedal and adjust the pedal stop so it contacts the pedal rod and tighten the nuts.

   Important: Ensure that the tension on the cable is not excessive or you will reduce the cable life.

1. Press down on the traction pedal and loosen the locknut securing the pedal stop to the floor plate.

2. Loosen the pedal stop until you obtain the desired transport speed.

3. Tighten the locknut securing the pedal stop.

The recommended replacement fluid is as follows:

Alternate fluids: If the Toro fluid is not available, other fluids may be used provided they meet all the following material properties and industry specifications. We do not recommend the use of synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product

Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation.

Important: The ISO VG 46 Multigrade fluid has been found to offer optimal performance in a wide range of temperature conditions. For operation in consistently high ambient temperatures, 18°C (65°F) to 49°C (120°F), ISO VG 68 hydraulic fluid may offer improved performance.

Premium Biodegradable Hydraulic Fluid-Mobil EAL EnviroSyn 46H

Important: Mobil EAL EnviroSyn 46H is the only synthetic biodegradable fluid approved by Toro. This fluid is compatible with the elastomers used in Toro hydraulic systems and is suitable for a wide-range of temperature conditions. This fluid is compatible with conventional mineral oils, but for maximum biodegradability and performance the hydraulic system should be thoroughly flushed of conventional fluid. The fluid is available in 19 L (5 gallon) containers or 55 gallon drums from your Mobil Distributor.

Important: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system fluid is available in 20 ml (2/3 oz) bottles. One bottle is sufficient for 15 to 22 L (4 to 6 gallons) of hydraulic fluid. Order Part No. 44-2500 from your authorized Toro distributor. This red dye is not recommended for use with biodegradable fluids. Use food coloring.

The hydraulic-fluid reservoir is filled at the factory with high quality hydraulic fluid. Before operating the machine each day, check the level of the hydraulic fluid. Your machine has a dipstick or a white plastic window on the front of the hydraulic-fluid reservoir (behind the seat on the left side) that is used to check the hydraulic-fluid level. The fluid should be between the window lines or the dipstick marks; if not, add the appropriate fluid.

Important: To prevent system contamination, clean the top of the hydraulic fluid containers before puncturing them. Ensure that the pour spout and funnel are clean.

1. Position the machine on a level surface.

   Note: Ensure that the machine has cooled down so the fluid is cold.

2. Check the fluid level according to the tank on your machine:

   • If your machine has a fuel gauge at the top of the fuel tank, locate the dipstick for the hydraulic system at the top of the leak detector tank (Figure 36) and proceed to step 3.

     

     Figure 36

     1. Dipstick
     2. Hydraulic tank plug
     3. Hydraulic tank
     4. Leak-detector tank

   • If your machine has a fuel sight gauge at the side of the fuel tank, locate the dipstick for the hydraulic system at the top of the hydraulic tank (Figure 37) and proceed to step 5.

     Note: If the fluid level is between the 2 marks on the sight window, the fluid level is sufficient.

     

     Figure 37

     1. Dipstick
     2. Hydraulic tank

3. Remove the dipstick and wipe it with a clean rag, then screw the dipstick back into the tank.

4. Remove the dipstick and check the fluid level. If the fluid is between the marks on the dipstick, the level is sufficient. If the fluid level is not between the marks, more fluid is needed.

5. Remove the cap from the hydraulic fluid tank and slowly fill the tank with the appropriate high-quality hydraulic fluid until the level is between the 2 marks on the sight window or dipstick.

   Note: Do not mix different types of hydraulic fluid.

6. Install the cap.

   Note: Perform a close visual inspection of the hydraulic components. Inspect them for issues (e.g., leaks, loose fasteners, missing parts, and improperly routed lines). Make any necessary corrections.

Hydraulic Fluid Capacity: 25.7 L (6.8 US gallons)

If the fluid becomes contaminated, have your authorized Toro distributor flush the system. Contaminated fluid looks milky or black when compared to clean fluid.

1. Clean the area around the filter mounting area (Figure 38). Place a drain pan under the filter and remove the filter.

   

   Figure 38

   1. Hydraulic-fluid filter

   Note: If you will not be draining the fluid, disconnect and plug the hydraulic line going to the filter.

2. Fill the replacement filter with the appropriate hydraulic fluid, lubricate the sealing gasket, and hand turn it until the gasket contacts the filter head. Then tighten it 3/4 turn further.

3. Fill the hydraulic reservoir with hydraulic fluid; refer to Hydraulic Fluid Specifications and Checking the Hydraulic-Fluid Level.

4. Start the machine and run it at idle for 3 to 5 minutes to circulate the fluid and remove any air trapped in the system. Shut off the engine and check the fluid level.

5. Dispose of the fluid and filter properly.

1. With ignition switch in the ON position, move the leak detector switch rearward and hold. After the 1-second delay elapses, the alarm should sound.

2. Release the leak-detector switch.

1. Move the ignition switch to the ON position. Do not start the engine.

2. Remove the hydraulic-tank cap from the neck of the tank.

3. Insert a clean rod or screwdriver into the tank neck and gently push down on the float switch (Figure 42); the alarm should sound after the 1-second delay.

   

   Figure 42

   1. Clean rod or screwdriver
   2. Warning buzzer
   3. Press down on the float switch

4. Release the float; the alarm should stop sounding.

5. Install the hydraulic-tank cap.

6. Move the ignition switch to the OFF position.

The leak detector alarm may sound for 1 of the following reasons:

• A leak of 118 to 177 ml (4 to 6 oz) has occurred.

• The fluid level in the main reservoir is reduced by 118 to 177 ml (4 to 6 oz) due to contraction of the fluid by cooling.

If the alarm sounds, turn off the machine as quickly as possible and inspect it for leaks. If the alarm sounds while operating on a green, drive off the green first. Determine the source of the leak and repair it before continuing operation.

If you do not find a leak and suspect a false alarm, move the ignition switch to the OFF position and allow the machine to stand for 1 to 2 minutes to allow the fluid levels to stabilize. Then start the machine and operate it in a non-sensitive area to confirm that no leak exists.

False alarms, due to fluid contraction, may be caused by extended idling of the machine after normal operation. A false alarm may also occur if you work the machine at a reduced workload after an extended period of a heavier workload. To avoid false alarms, turn the machine off rather than idling for extended periods.

1. Lift up on the footrest and swing it open, allowing access to the center cutting unit position (Figure 44).

   Caution

   The footrest can pinch fingers if it falls into the closed position.

   Keep your fingers clear of the area where the footrest seats while it is open.

   

   Figure 44

   4. Motor-retaining bar

7. Mount a grass basket onto the basket hooks on the suspension arm.

8. Repeat this procedure for the other cutting units.

1. Park the machine on a clean level surface, lower the cutting units to the ground until the suspension hydraulics are fully extended, shut off the engine, and set the parking brake.

2. Push the motor retaining bar out of the slots on the motor toward the cutting unit and remove the motor from the cutting unit.

   

   Figure 48

   1. Reel motor
   2. Motor-retaining bar

3. Move the motor to the storage location on the front of the suspension arm (Figure 49).

   

   Figure 49

   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. If you must move the traction unit without the cutting units installed, secure them to the suspension arms using cable ties.

4. Open the latches on the suspension-arm bar of the cutting unit you are removing (Figure 45).

5. Disconnect the latches from the cutting-unit bar.

6. Roll the cutting unit out from under the suspension arm.

7. Repeat steps 2 through 6 for the other cutting units as required.

1. Stop the machine, set the parking brake, and turn the ignition key to the OFF position.

2. Move the functional-control lever to the TRANSPORT position.

3. Ensure that the backlap lever is set to the FORWARD (F) position.

4. Get off the seat.

5. Hold the raise/lower mow control in the RAISED position.

6. Turn the ignition switch to the RUN position.

7. Count the codes as they begin to flash (you may release the raise/lower mow control once they begin flashing).

When finished, turn the key to the OFF position to exit diagnostic mode.

The system will display the last 3 faults that occurred in the last 40 hours. It displays the faults through a series of blinking lights, as follows:

• If there are no faults, the light will blink steadily at a medium rate without pauses (1 Hz).

• If there is a fault, it will first blink the tens place, followed by a pause, followed by the ones place. For the following examples, a # represents a blink. Examples:

  • If the code is 15, the blink pattern will be #_#####

  • If the code is 42, the blink pattern will be ####_##

  • If the code is 123, the blink pattern will be ############_###

• If there are more than 1 fault, the tens place of the next fault will begin after a pause after the ones place of the first fault.

  Note: The system stores only the 3 most recent fault codes.

For a list of error codes, refer to your authorized Toro distributor or the Service Manual.
