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.

The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started.

Crankcase capacity is approximately 3.7 l (3.9 quarts) with the filter.

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. If the oil level is between the “full and “add marks, no oil addition is required.

Important: Be sure to keep the engine oil level between the upper and lower limits on the oil gauge. Engine failure may occur as a result of over filling or under filling the engine oil.

1. Position the machine on a level surface.

2. Remove the dipstick and wipe it with a clean rag (Figure 28). Push the dipstick into the tube and make sure it is seated fully. Remove the dipstick from the tube and check the level of oil. 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.

   Important: Make sure that the dipstick is removed 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 27. This clearance is necessary to permit venting when filling, which prevents oil from overrunning into breather.

   

   Figure 27

   1. Note clearance
   

   Figure 28

   1. Filler cap
   2. Dipstick

3. Replace the dipstick.

4. Start and run the engine at idle for 30 seconds, then shut the engine off. Wait 30 seconds, then repeat steps 2–3.

   Important: Check the level of oil every 8 operating hours or daily. Change the oil and filter initially after the first 50 hours of operation, thereafter change the oil and the filter every 150 hours. However, change the oil more frequently when the engine is operated in extremely dusty or dirty conditions.

5. 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 US 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.

Biodiesel Ready

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

1. Clean around the fuel-tank cap (Figure 29).

   

   Figure 29

   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. Do not overfill. Install the cap.

4. Wipe up any fuel that may have spilled.

The capacity of the cooling system is approximately 4.6 L (4.9 quarts). Refer to Cleaning the Radiator Screen.

4. Radiator-fill cap

The cooling system is filled 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 31).

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

   

   Figure 31

   1. Reserve tank

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.

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 machines reservoir is filled at the factory with approximately 20.8 L (5.5 gallons) of high quality hydraulic fluid. Check the level of the hydraulic fluid before the engine is first started and daily thereafter. 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, 65° F (18° C) to 120° F (49° C), 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.

Note: 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 oil. Order part no. 44-2500 from your authorized Toro distributor. This red dye is not recommended for use with biodegradable fluids.

Important: Regardless of hydraulic fluid type used, any machine used for mowing fairways, verticutting or used during ambient temperatures above 85°F (29°C) should have Oil Cooler Kit, Part No. 117-9314, installed.

1. Position the machine on a level surface and stop the engine.

2. Place a drain pan under the fuel filter.

3. Open the drain plug on the fuel filter approximately one turn and drain any accumulated water (Figure 34). Tighten the plug after draining.

   Note: Because the accumulated water will be mixed with diesel fuel, drain the fuel filter into a suitable container and dispose of it properly.

   

   Figure 34

   2. Drain plug

The tires are over-inflated at the factory for shipping purposes. Reduce the pressure to the proper levels before starting the unit.

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).

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 Adjusting the Reel to Bedknife in 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.

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.

To ensure optimum performance of the brake system, burnish (break-in) the brakes before using the machine. To burnish the brakes, firmly apply the brakes and drive the machine at mowing speed until the brakes are hot, as indicated by their smell. An adjustment to the brakes may be required after break-in; refer to Adjusting the Brakes.

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

Note: Before mowing greens with the machine, find a clear area and practice starting and stopping, raising and lowering the cutting units, turning, etc. This training period will be beneficial to the operator in gaining confidence in the performance of the machine.

Note: Before mowing, 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 bedknife.

1. Approach the green with the shift selector in the No. 1 position. Start on one edge of the green so that the ribbon procedure of cutting may be used.

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

2. Actuate the mow pedal as the front edge 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: Familiarize yourself with the fact that the No. 1 cutting unit reel is delayed and therefore, you should practice to try to gain the required timing necessary to minimize the cleanup mowing operation.

3. 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 41). 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 (Figure 41).

   

   Figure 41

   1. Alignment marker
   2. Cut grass on left
   3. Keep focal spot 1.8-3 m (6-10 ft) ahead of the machine.

4. As the front of the baskets cross the edge of the green, depress the lift pedal.

   Note: This will stop the reels and lift the cutting units. Timing of this procedure is important, so the mowers do not cut into the fringe area. However, as much of the green as possible should be cut to minimize the amount of grass left to mow around the outer periphery

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

   Note: This will assist in getting the machine more quickly aligned for the next pass. Follow the same procedure for turning in the opposite direction. It is a good practice to try to make as short of a turn as possible. However, turn in a wider arc during warmer weather to minimize the possibility of bruising the turf.

   Important: The machine should never be stopped 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.

6. Finish cutting the green by mowing the outer periphery and replace the flags.

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

   Note: At the end of the periphery cut, momentarily pull back on the raise/lower mow lever to shut the reels off without raising them. Continue moving forward until the reel stops rotating, then, drive off the green and raise the reels (This will help prevent dribbling grass onto the green while raising the reels).

7. 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 will add unnecessary weight to the machine, thereby increasing the load on the engine, hydraulic system, brakes, etc.

Make sure the cutting units are in the full up position. 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 a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.

To transport the machine:

1. If using a trailer, connect it to the towing vehicle and connect the safety chains.

2. If applicable, connect the trailer brakes.

3. Load the machine onto the trailer or truck.

4. Stop the engine, remove the key, set the brake, and close the fuel valve.

5. Use the metal tie down loops on the machine to securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes.

Use extreme caution when loading the machine onto a trailer or a truck. One full-width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the machine (Figure 42). The lower rear section of the machine frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full-width ramp provides a surface for the frame members to contact if the machine starts to tip backward. If it is not possible to use one full-width ramp, use enough individual ramps to simulate a full-width continuous ramp.

The ramp should be long enough so that the angles do not exceed 15 degrees (Figure 42). A steeper angle may cause mower components to get caught as the unit moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip backward. If loading on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

Important: Do not attempt to turn the machine while on the ramp; you may lose control and drive off the side.

Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the machine to tip backward.

At the completion of the mowing operation, thoroughly wash the machine with a garden hose without a nozzle so excessive water pressure will not cause contamination and damage to seals and bearings. Never wash a warm engine or electrical connections with water.

After cleaning, it is recommended the machine be inspected for possible hydraulic fluid leaks and damage or wear to hydraulic and mechanical components. The cutting units should be checked for sharpness. Also, lubricate the traction pedal and brake shaft assembly with SAE 30W oil or spray lubricant to deter corrosion and help keep the machine performing satisfactorily during the next mowing operation.

In case of an emergency the machine can be towed for a short distance (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 3-5 km/h (2-3 mph) because the drive system may be damaged. If the machine must be moved a considerable distance, 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 43).

   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 43). Do not start the engine when the valve is open.

1. Position the machine on a level surface, lower the cutting units, stop the engine, 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.

4. Start the engine and run at low idle speed. If the engine stalls, increase the engine speed.

5. Switch the Backlap Switch to the reverse (R) position (Figure 59).

6. On the InfoCenter pull up the Main Menu and scroll down to Settings.

7. In the Settings menu scroll down to Backlap rpm and use the button to select the desired backlap speed.

8. 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.

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

10. If the reels stall or become erratic while backlapping, select a higher reel speed setting until the speed stabilizes.

11. To make an adjustment to the cutting units while backlapping, turn the reels off by moving the Raise/Lower Mow control rearward and stop the engine. After completing adjustments, repeat steps 4 through 9.

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

13. When finished, return the backlap switch 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 switch is not returned to the forward (F) position after backlapping, the cutting units will not raise or function properly.
