The functional control lever (Figure 17) 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

• Front Position—used for transport

The hour meter (Figure 17) indicates the total hours that the machine has operated. It starts to function whenever the key switch is rotated to the ON position.

Insert the key into the switch (Figure 17) 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.

Rotate the lever (Figure 17) rearward to loosen the adjustment, raise or lower the steering arm for your comfort, then, rotate the lever forward to tighten the adjustment.

The light (Figure 17) glows and the engine automatically shuts off whenever the engine coolant temperature is too high.

The light (Figure 17) glows if the engine-oil pressure drops below a safe level.

The light (Figure 17) glows if the battery charge is low.

When the glow plug indicator light (Figure 17) is lit, it indicates the glow plugs are on.

Moving the control (Figure 17) 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.

If the engine shuts off because it is overheated, press the override button (Figure 17) in and hold it until you can move the machine to a safe location and allowed to cool down.

Note: When using the override button, you must hold it down continuously to operate. Do not use it for extended periods of time.

Use the backlap lever (Figure 18) in conjunction with the raise/lower mow control lever and the reel speed control for backlapping the reels.

A selection of Toro approved attachments and accessories are 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, you must check the oil level before and after you start the engine for the first time.

Crankcase capacity is approximately 3.7 L (3.9 US 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: 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 22). Push the dipstick into the tube and make sure that 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 21. This clearance is necessary to permit venting when filling, which prevents oil from overrunning into breather.

   

   Figure 21

   1. Note clearance
   

   Figure 22

   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. Using winter-grade fuel at lower temperatures provides lower flash point and cold flow characteristics, which eases starting and reduce fuel filter plugging.

Use of summer grade fuel above –7°C (20°F) contributes 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 23).

   

   Figure 23

   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 3.2 L (3.3 US qt). Refer to Cleaning the Radiator Screen.

Figure 24

2. Radiator

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 25). It should be between the lines on the reserve tank when the engine is cold.

   

   Figure 25

   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.

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

2. Place a drain pan under the fuel filter (Figure 27).

3. Open the drain plug on the bottom of the fuel filter and drain any accumulated water (Figure 27). 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.

Vary the tire pressure for the front wheels, depending upon your turf conditions, from a minimum of 55 kPa to a maximum of 83 kPa (8 to 12 psi).

Vary the tire pressure for the rear wheel from a minimum of 55 kPa to a maximum of 103 kPa (8 to 15 psi).

Refer to Adjusting the Reel to Bedknife in the Cutting Unit Operator’s Manual.

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 is required to break-in the machine.

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. You may need to adjust the brakes after break-in; refer to Adjusting the Brakes.

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 the machine.

The safety interlock system prevents the engine from starting unless:

• The traction pedal is in neutral.

• The functional control lever is in neutral.

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 MOW or TRANSPORT.

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 be sure the interlock system is operating correctly:

1. Sit on the seat, move the traction pedal to NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Try to depress the traction pedal. The pedal should not depress, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

2. Sit on the seat, move the traction pedal to NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Move the functional control lever to mow or transport and try to start the engine. The engine should not crank, 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 NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Start the engine and move the functional control lever to mow or transport. The engine should kill, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

4. Sit on the seat, move the traction pedal to NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Start the engine. Release the parking brake, move the functional control lever to mow, and rise from the seat. The engine should kill, 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 NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Start the engine. Move the raise/lower mow control forward to lower the cutting units. The cutting units should lower but not start rotating. If they do, the interlock system is not operating correctly. Correct the problem.

To achieve a consistent, high quality-of-cut and a uniform after cut appearance, it is important that the reel speed control (located on the manifold block under seat) be correctly set.

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. Using the appropriate graph (See Figure 28) for 5-, 8-, 11- or 14-blade cutting units, determine the proper reel speed setting.

   

   Figure 28

4. To set the reel speed, rotate the knob (Figure 29) until the indicator arrows are in line with the number designating desired setting.

   

   Figure 29

   1. Reel speed control

   Note: Reel speed can be increased or decreased to compensate for turf conditions.

To assist in aligning the machine for successive cutting passes, do the following to the No. 2 and No. 3 cutting unit baskets:

1. Measure in approximately 12.7 cm (5 inches) from the outer edge of each basket.

2. Either place a strip of white tape or paint a line onto each basket paralleling the outer edge of each basket (Figure 30).

   

   Figure 30

   1. Alignment strip
   2. Approximately 12.7 cm (5 inches)
   3. Cut grass on right
   4. Keep focal spot 1.8–3 m (6–10 ft) ahead of the machine.

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 help you in gaining confidence in the performance of the machine.

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 functional control lever in the middle position. Start on one edge of the green so that the ribbon procedure of cutting may be used. 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. 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. 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 30 and Figure 31). 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 30 and Figure 31).

   

   Figure 31

   1. Alignment strip
   2. Approximately 12.7 cm (5 inches)
   3. Cut grass on left
   4. 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. 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. 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. 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. Replace the flag.

   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. 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.

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.

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. Shut off 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 32). 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 1 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 32). 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 minimizes 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.

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

After cleaning, inspect the machine for possible hydraulic fluid leaks and damage or wear to hydraulic and mechanical components. Check the cutting units for sharpness. Also, lubricate the traction pedal and brake shaft assembly with SAE 30 oil or 31 spray lubricant to deter corrosion and help keep the machine performing satisfactorily during the next mowing operation.

In case of an emergency, you can tow the machine for 400 m (1/4 mile). But, this should not be a 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 you must transport the machine more than 400 m (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 33).

2. Before starting the engine, close the bypass valve by rotating it so that the slot is horizontal (Figure 33).

   Important: Do not start the engine when the valve is open.

The machine has grease fittings that must be lubricated regularly with No. 2 lithium grease. If the machine is operated under normal conditions, lubricate all bearings and bushings after every 50 hours of operation. Lubricate fittings immediately after every washing, regardless of the interval listed.

Lubricate the following machine bearings and bushings:

• Rear wheel hub (1) (Figure 34)

• Castor bearing (1) (Figure 34)

• Steering cylinder (2) (Figure 34)

• Lift arms (3) (Figure 35)

• Traction pedal pivot (1) (Figure 36)

• Carrier frame pivot (3) (Figure 37)

1. Wipe the grease fitting clean so foreign matter cannot be forced into the bearing or bushing.

2. Pump grease into the bearing or bushing.

3. Wipe up excess grease.

4. Apply grease to the reel motor spline shaft and onto the lift arm when the cutting unit is removed for service.

5. Apply a few drops of SAE 30 engine oil or spray lubricant (WD 40) daily to all pivot points after cleaning.

Note: Refer to the cutting unit Operator’s Manual for cutting unit lubrication requirements.
