1. Parking-brake switch

Service braking is achieved by the hydraulic transmission system. When the forward or reverse traction pedals are released or the engine speed is reduced, service braking becomes effective and travel speed is automatically reduced. To increase the braking effect, push the traction pedal into the NEUTRAL position. Service braking is effective on the front wheels only.

In the event of service brake failure, turn the ignition off to bring the machine to a standstill.

Forward travel: Press the forward traction pedal to increase forward travel speed. Release the pedal to reduce speed (Figure 16).

Reverse travel: Press the reverse traction pedal to increase reverse travel speed. Release the pedal to reduce speed (Figure 16).

Stop (Neutral): To stop the machine, use 1 of the following procedures:

• Reduce your foot pressure on the traction pedal and allow it to return to the neutral position. The machine dynamically brakes to a smooth stop.

• Tap or hold the reverse pedal briefly. This stops the machine faster than dynamic braking.

Before starting the machine each day, perform the Each Use/Daily procedures listed in .

Note: The engine stops if the operator leaves the seat without engaging the parking brake.

Engine Start Lockout: The engine can only be started when the forward/reverse travel pedal is in the Neutral position, the cutting unit drive switch is in the Off position and the parking brake is engaged. When these circumstances are satisfied, switches are activated permitting the engine to be started.

Engine Run Interlock: Once the engine is started the operator must be seated before the parking brake is disengaged for the engine to continue to run.

Cutting Unit Drive Lockout: The drive to the cutting units is only possible when the operator is seated. If the operator raises off the seat for a period of more than one second, a switch is activated and the drive to the cutting units is automatically disengaged. To engage the drive to the cutting units, the operator must return to the seat, then operate the cutting unit drive switch to the Off position before moving it back to the On position. If the operator rises off the seat for a brief moment during normal work, drive to the cutting units is not affected.

The engine can only be started with the cutting unit drive switch in the Off position.

You can fold the roll bar down to allow access into areas of restricted height.

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

2. Support the weight of the upper frame of the roll bar while removing the snap pins and clevis pins from the pivot brackets (Figure 26).

3. Carefully lower the frame downward until it rests on the stops.

4. Insert the clevis pins in the lower holes and secure them with the snap pins to support the upper frame in its lowered position.

5. To raise the frame, follow these instructions in reverse order.

• Keep all nuts, bolts, and screws correctly torqued ensure that the equipment is in safe working condition.

• Replace worn or damaged parts for safety.

• Ensure that the seat belt and mountings are in safe working order.

• Wear the seat belt when the roll bar is raised and no seat belt when the roll bar is lowered.

Important: The roll bar is an integral safety device. Keep the roll bar in the raised position when operating the mower. Lower the roll bar temporarily only when absolutely necessary.

Important: You must bleed the fuel system before starting the engine if you are starting the engine for the first time, the engine has stopped due to lack of fuel, or you have performed maintenance on the fuel system; refer to Bleeding the Fuel System.

Important: This machine is fitted with an engine start lockout; refer to Understanding the Operator Presence Controls.

1. Sit on the seat, keep your foot off the traction pedals so that it is in NEUTRAL, ensure that the cutting unit drive switch is off, engage the parking brake, and set the throttle to the 70 percent full-throttle position.

2. Turn the key to the on position I and check that the engine oil pressure and battery charge warning lights illuminate.

3. If the engine is cold, turn the key to the preheat position II so that the pre-heat indicator light is on (Figure 12). Hold it for 5 seconds to heat the glow plugs.

4. After preheating the glow plugs or if the engine is already warm, turn the key to the start position III and hold it there to crank the engine.

   Crank the engine for no longer than 15 seconds. Release the key back to position I when the engine starts.

5. Run the engine at low idle speed until it warms up.

Important: When the engine is operating all warning lights should be off. If a warning light illuminates, shut off the engine immediately and fix the issue before starting the engine.

1. Move all controls to NEUTRAL, engage the parking brake, move the throttle to the low idle position and allow the engine to reach low idle speed.

   Important: Allow the engine to idle for 5 minutes before shutting it off after a full load operation. Failure to do so may lead to trouble on a turbo-charged engine.

2. Let the engine idle for 5 minutes.

3. Turn the key to position 0.

   If the engine fails to shut off when the key is turned to 0, operate the engine shutoff lever in the forward direction (Figure 27).

   

   Figure 27

The rear grass deflectors must always be correctly fitted. The deflectors should be set as low as possible to deflect grass discharge to the ground (Figure 28).

Figure 28

With all cutting units set at the same HOC via the indicator rings, it may be noticeable that the center unit produces a higher cut finish compared to the wing units. The center unit is pulled and the wing units are pushed; this presents marginally different cutting angles relative to the ground. The amount of HOC variation which results from this will be influenced by the terrain, but satisfactory results can usually be achieved by setting the center cutting unit HOC indicator ring lower than the wing unit settings.

The cutting units may be raised or lowered independently using the bank of 3 lift control switches.

1. To lower the cutting units, operate the lift control switches in a downward direction and release.

   The cutting unit drive switch must be on (forward) to do this, the reel drive will engage when the cutting units are approximately 150 mm (6 inches) above ground level. The cutting units are now in ‘float’ mode and will follow the ground contours.

2. To raise the cutting units, operate the lift control switches in an upward direction and hold in position 3. If the cutting unit drive switch is in the On position the reel drive will disengage immediately.

3. Release the lift control switches when the cutting units are at the required height.

   The control switches will automatically return to position 2 (neutral) and the arms are hydraulically locked into position.

To activate, press the Auto Limited Lift switch to the On position (Figure 29).

To deactivate, press the Auto Limited Lift switch to the Off position (Figure 29).

Manual limited lift using the 3 lift control switches is always available regardless of the position of the Auto switch.

Figure 29

To raise the cutting units to the limited lift position: momentarily operate the switches in an upward direction.

The reel drive will disengage immediately and the cutting units will stop raising, approximately 150 mm (6 inches) above ground level.

This operates with the cutting units lowered and rotating.

Auto limited lift in reverse causes the cutting units to rise automatically to the limited lift position when reversing. They will return to the floating position when returning to forward travel. The cutting units continue to rotate during this operation.

7. Using a suitable strong wooden instrument, remove the blockage. Ensure that the wooden instrument is properly supported in the cutting unit and avoid the use of excessive force to prevent damage.

8. Ensure that the wooden instrument is removed from the cutting unit before restarting the power source.

9. Repair or adjust the cutting unit if required.

A variable hydraulic weight transfer system is provided for improving tire grip with the grass surface—traction assistance.

Hydraulic pressure in the cutting unit lift system provides a lifting force which reduces the weight of the cutting units on the ground and transfers the weight as a downward force onto the tires of the machine. This action is known as weight transfer.

To engage weight transfer: The amount of weight transfer can be varied to suit operating conditions by rotating the weight transfer hand wheel (Figure 31) as follows:

1. Release the valve locknut 1/2 turn counterclockwise and hold (Figure 31).

2. Rotate the valve hand wheel (Figure 31) counterclockwise to reduce weight transfer or clockwise to increase weight transfer.

3. Tighten the nut.

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: approximately 6.0 L (6.3 US qt) 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 15W-40 (above 0 degrees F)

• Alternate oil: SAE 10W-30 or 5W-30 (all temperatures)

Toro Premium Engine oil is available from your distributor in either 15W-40 or 10W-30 viscosity.

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

1. Park the machine on a level surface, shut off the engine, engage the parking brake, and remove the key from the ignition switch.

2. Open the hood.

3. Remove the dipstick, wipe it clean, and install it(Figure 53).

   

   Figure 53

   1. Dipstick

4. Remove dipstick and check oil level on dipstick.

   The oil level should be up to the Full mark .

5. If the oil level is below the Full mark, remove the fill cap (Figure 54) and add oil until level reaches the Full mark on dipstick. Do not overfill.

   

   Figure 54

   1. Oil fill cap

6. Install the oil fill cap and close the hood.

1. Remove the drain plug (Figure 55) and let the oil flow into a drain pan.

   

   Figure 55

   1. Oil drain plug

2. When the oil stops, install the drain plug.

3. Remove the oil filter (Figure 56).

   

   Figure 56

   1. Oil filter

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

5. Install the replacement oil filter to the filter adapter. Turn the oil filter clockwise until the rubber gasket contacts the filter adapter, then tighten the filter an additional 1/2 turn.

   Important: Do not over-tighten the filter.

6. Add oil to the crankcase; refer to Checking the Engine-Oil Level.

Drain and clean the fuel tank if the fuel system becomes contaminated or if the machine is to be stored for an extended period. Use clean fuel to flush out the tank.

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

You must bleed the fuel system before starting the engine if any of the following situations have occurred:

• Initial start-up of a new machine.

• Engine has stopped running because lack of fuel.

• Maintenance was performed on fuel system components; i.e., filter replaced, separator serviced, etc.

1. Park the machine on a level surface and ensure that the fuel tank is at least half full.

2. Open the hood.

3. Turn the key in the ignition switch to the ON position and crank the engine. The mechanical pump will suck fuel out of the tank, fill the fuel filter and fuel hose and force the air into the engine. This could take some time to fully purge all the air out of the system and the engine might fire erratically until all air is purged out. When all air is purged and the engine is running smoothly, it should be run for a few minutes to ensure that it is fully purged.

Important: Replace the fuel filter canister periodically to prevent wear of the fuel injection pump plunger or the injection nozzle, due to dirt in the fuel.

1. Place a clean container under the fuel filter canister (Figure 57).

2. Clean the area where the filter canister mounts.

   

   Figure 57

   1. Fuel filter

3. Remove the filter canister and clean the mounting surface.

4. Lubricate the gasket on the filter canister with clean oil.

5. Install the new filter canister by hand until the gasket contacts mounting surface.

6. Bleed the fuel system; refer to Bleeding the Fuel System.

Inspect all electrical connections and cables and replace any which are damaged or corroded. Spray a good-quality water inhibitor onto exposed connections to prevent moisture ingress.

Note: When removing the battery, always disconnect the negative (-) cable first.

Note: When installing the battery, always connect the negative (-) cable last.

Raise the engine cover. Remove any corrosion from the battery terminals using a wire brush and apply petroleum jelly to the terminals to prevent further corrosion. Clean the battery compartment.

Under normal operating conditions the battery will not require any further attention. If the machine has been subject to continuous use under high ambient temperature conditions, the battery electrolyte may require topping up.

Remove the cell covers and top up with distilled water to a height 15 mm below the top of the battery. Install the cell covers.

Note: Check the condition of the battery cables. Install new cables when current ones are showing signs of wear or damage and tighten any loose connections as necessary.

Check the battery condition. Keep the terminals and the entire battery case clean because a dirty battery will discharge slowly. To clean the battery, wash the entire case with a solution of baking soda and water. Rinse it with clear water.

Check the air pressure in the front and rear tires. Refer to the chart below for the correct pressure.

Important: Maintain correct tire pressure in all tires to ensure correct contact with the turf.

Torque the wheel nuts to 200 N-m (148 ft-lb) for the front axle, and 54 N-m (40 ft-lb) for the rear axle.

Check the condition and security of the cable and operating mechanism at the speed control pedals and transmission pump ends.

• Remove buildup of dirt, grit and other deposits.

• Ensure that the ball joints are securely anchored and check that mounting brackets and cable anchors are tight and free from cracks.

• Inspect end fittings for wear, corrosion, broken springs, and replace if necessary.

• Ensure that the rubber seals are correctly located and are in good condition.

• Ensure that the articulating sleeves supporting the inner cable are in good condition and firmly attached to the outer cable assembly at the crimped connections. If there are any signs of cracking or detachment install a new cable immediately.

• Check that sleeves, rods, and inner cable are free from bends, kinks, or other damage. If they are not, install a new cable immediately.

• With the engine switched off, operate the pedal controls through the entire range and ensure that the mechanism moves smoothly and freely to the neutral position without sticking or hanging up.

4. Insert a pry bar between the alternator and the engine and pry out on the alternator.

5. When you achieve the proper tension, tighten the alternator, brace and pivot bolts to secure the adjustment.

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

The reservoir is filled at the factory with approximately 32 L (8.5 US gallons) of high-quality hydraulic fluid. The best time to check the hydraulic oil is when the fluid is cold. The machine should be in its transport configuration. If the oil level is below the ‘add’ mark on the dipstick, add oil to bring the oil level to the middle of the acceptable range. Do not overfill the reservoir. If the oil level is between the ‘full’ and the ‘add’ marks, no oil addition is required.

The recommended replacement fluid is:

Toro Premium All Season Hydraulic Fluid

(available in 19 liter (5 US gallon) containers or 208 liter (55 US gallon) drums—see the parts documentation or your Toro distributor for part numbers)

Alternative fluids: If the Toro fluid is not available, other conventional, petroleum-based fluids may be used, provided that they meet all of the following material properties and industry specifications. Check with your oil supplier to see whether the oil meets these specifications.

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.

The proper hydraulic fluids must be specified for mobile machinery (as opposed to industrial plant usage), multiweight-type, with ZnDTP or ZDDP antiwear additive package (not an ashless-type fluid).

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 fl oz) bottles. One bottle is sufficient for 15 to 22liters (4 to 6 US gallons) of hydraulic oil. Order part 44-2500 from your Authorized Toro Distributor.

8. Check that a thin piece of paper can be cut cleanly at all points along the cutting edges while rotating the reels by hand.

9. If further back lapping is necessary repeat steps 2 through 8.

10. Thoroughly remove and wash off all traces of the carborundum paste from the reels and bedknives.

It will be necessary to carry out a grinding operation to correct reel edges or bedknife edges that have become excessively rounded or distorted. Bedknives that are nearing the end of their wear life should be replaced. The new blades should be ground on their holders prior to fitting. When grinding operations are necessary it is essential that both the reels and the bedknives are ground at the same time. The only exception to this rule is when a new reel is fitted, in which case it is only necessary to grind the bedknife. All such grinding operations should be carried out by your authorized dealer on a quality, well-maintained reel / bedknife grinding machine
