A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or Distributor or go to www.Toro.com for a list of all approved attachments and accessories.

To best protect your investment and maintain optimal performance of your Toro equipment, count on Toro genuine parts. When it comes to reliability, Toro delivers replacement parts designed to the exact engineering specification of our equipment. For peace of mind, insist on Toro genuine parts.

The engine is shipped with 3.7 L (3.9 US qt) (w/filter) of oil in the crankcase; however, you must check the oil level before and after starting the engine the first time.

Use high-quality engine oil that meets the following specifications:

• API Classification Level Required: CH–4, CI–4 or higher.

• Preferred oil: SAE 10W–30

• Alternate oil: SAE 15W–40

Toro Premium Engine oil is available from your distributor in the 10W–30 viscosity. See the parts catalog for part numbers.

Note: The best time to check the engine oil is when the engine is cool before it has been started for the day. If it has already been run, allow the oil to drain back down to the sump for at least 10 minutes before checking. If the oil level is at or below the Add mark on the dipstick, add oil to bring the oil level to the FULL mark. Do not overfill.

Important: Keep the engine oil level between the upper and lower limits on the oil gauge; the engine may fail if you run it with too much or too little oil.

1. Position the machine on a level surface.

2. Remove the dipstick and wipe it with a clean rag (Figure 23).

   Important: Remove the dipstick while filling the engine with oil. When adding engine oil or filling oil, there must be clearance between the oil fill device and the oil fill hole in the valve cover as shown in Figure 22. This clearance is necessary to permit venting when filling, which prevents oil from overrunning into breather.

   

   Figure 22

   1. Note clearance
   

   Figure 23

   1. Filler cap
   2. Dipstick

3. Push the dipstick into the tube and make sure it is seated fully.

4. Remove the dipstick from the tube and check the level of oil.

   Note: If the oil level is low, remove the filler cap from the valve cover and slowly add enough oil to raise the level to the FULL mark on the dipstick. Add the oil slowly and check the level often during this process. Do not overfill.

5. Replace the dipstick.

6. Start and run the engine at idle for 30 seconds, then shut the engine off. Wait 30 seconds, then repeat steps 2 through 5.

7. Install the filler cap and dipstick firmly in place.

Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness.

Fuel tank capacity: 22.7 L (6 U.S. gallons)

Use summer grade diesel fuel (No. 2-D) at temperatures above -7° C (20° F) and winter grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Use of winter grade fuel at lower temperatures provides lower flash point and cold flow characteristics which will ease starting and reduce fuel filter plugging.

Use of summer grade fuel above -7° C (20° F) will contribute toward longer fuel pump life and increased power compared to winter grade fuel.

1. Clean around the fuel-tank cap (Figure 24).

   

   Figure 24

   1. Fuel-tank cap

2. Remove the fuel-tank cap.

3. Fill the tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck.

   Important: Do not overfill.

4. Install the cap.

5. Wipe up any fuel that may have spilled.

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur. Observe the following precautions:

• The biodiesel portion of the fuel must meet specification ASTM D6751 or EN14214.

• The blended fuel composition should meet ASTM D975 or EN590.

• Painted surfaces may be damaged by biodiesel blends.

• Use B5 (biodiesel content of 5%) or lesser blends in cold weather

• Monitor seals, hoses, gaskets in contact with fuel as they may be degraded over time.

• Fuel filter plugging may be expected for a time after converting to biodiesel blends.

• Contact your distributor if you wish for more information on biodiesel

The capacity of the cooling system is approximately 4.6 L (4.9 US qt). Keep the radiator screen clean; refer to Cleaning the Radiator Screen.

Fill the cooling system with a 50/50 solution of water and permanent ethylene glycol antifreeze. Check the level of the coolant at the beginning of each day before starting the engine.

1. Park the machine on a level surface.

2. Check the coolant level (Figure 26).

   Note: It should be between the lines on the reserve tank when the engine is cold.

   

   Figure 26

3. If the coolant is low, remove the reserve tank cap and add a 50/50 mixture of water and permanent ethylene glycol antifreeze. Do not overfill.

4. Install the reserve-tank cap.

The hydraulic-fluid reservoir is filled at the factory with approximately 25.7 L (6.8 US gallons) of high quality hydraulic fluid. Before operating the machine each day, check level of the hydraulic fluid in the white plastic window on the front of the hydraulic-fluid reservoir (behind the seat on the left side). The fluid should be between the lines in the window; if not, add an appropriate fluid as described in the following sections:

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 oil 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 oil is available in 20 ml (2/3 oz) bottles. One bottle is sufficient for 15-22 L (4-6 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.

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 Oil Cooler Kit installed; refer to Installing the Oil Cooler (optional).

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.

Before checking the reels, disconnect the cutting unit power disconnect couplers; refer to Cutting Unit Power Disconnect Connectors. Connect them when finished.

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

Vary the tire pressure for the rear wheel from a minimum of 83 to a maximum of 110 kPa (12 psi to 16 psi).

To ensure even distribution, torque the brakes in a star pattern.

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.

Important: Do not use ether or other types of starting fluid.

Note: You may need to bleed the fuel system before starting the engine if any of the following situations have occurred:

• Initial start up of a new engine

• The engine has ceased running due to lack of fuel.

• Maintenance has been performed upon fuel system components; ie. filter replaced, etc.

Refer to your engine owner’s manual.

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

2. Remove your foot from the traction pedal and make sure the pedal is in the NEUTRAL position.

3. Move the throttle lever to the SLOW position.

4. Insert the key into the switch and rotate it to the ON position. Hold it in the ON position until the glow-plug-indicator light goes off (approximately 6 seconds).

5. Turn the ignition key to the START position.

   Important: To prevent overheating of the starter motor, do not engage the starter longer than 10 seconds. After 10 seconds of continuous cranking, wait 60 seconds before engaging the starter motor again.

6. Release the key when the engine starts and allow it to move to the ON position.

7. Allow the engine to warm up for a few minutes before operating.

   Important: When starting the engine for the first time or after an overhaul of the engine, operate the machine in forward and reverse for one to two minutes. Turn the steering wheel to the left and right to check the steering response. Then shut the engine off (see Stopping in Starting and Stopping the Engine) and wait for all moving parts to stop. Check for oil leaks, loose parts and any other noticeable malfunctions.

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

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

3. Close the fuel-shutoff valves before storing the machine.

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 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 off.

• 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 turn over 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 kill, 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.

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 rear of cutting unit to ensure that the nuts on the bedbar adjusting screws are not resting on work surface (Figure 28).

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 will be 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 one 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 away 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 36). 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 will stop the reels and lift 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 assists in getting 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 will minimize the turf bruising.

   

   Figure 36

   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: Due to the nature of the power steering system, the steering wheel will not return to its original position after a turn has been completed.

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

7. If the leak detector alarm sounds 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 alarm 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 of 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 adds 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 will not contaminate and damage the seals and bearings. Never 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 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.

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.

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

• Use a full-width ramp 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 less than 0.4 km (1/4 mile); however, Toro does not recommend this as standard procedure.

Important: Do not tow the machine faster than 3 to 5 km/h (2 to 3 mph) because it may damage the drive system. If the machine must be moved further 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 37).

   

   Figure 37

   1. Bypass valve-slot shown in closed (horizontal) position

2. Before starting the engine, close the bypass valve by rotating it so that the slot is horizontal (Figure 37). Do not start the engine when the valve is open.
