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

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, lower the cutting units, engage the parking brake, shut off the engine, and remove the key from the ignition switch.

2. Open the hood.

3. Remove the dipstick, wipe it clean, and install it(Figure 24).

   

   Figure 24

   1. Dipstick

4. Remove the dipstick and check the oil level on the 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 25) and add oil until the level reaches the Full mark on the dipstick. Do not overfill.

   

   Figure 25

   1. Oil-fill cap

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

The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol antifreeze.

1. Clean debris off of the screen, oil cooler, and front of the radiator daily and more often if conditions are extremely dusty and dirty. Refer to Removing Debris from the Cooling System.

2. Check the level of the coolant in the expansion tank (Figure 26).

   Note: The coolant level should be between the marks on the side of the tank.

   

   Figure 26

   1. Expansion tank

3. If the coolant level is low, remove the expansion-tank cap and replenish the system.

   Note: Do not overfill.

4. Install the expansion-tank cap.

Use only clean, fresh diesel fuel with low (<50 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: 45 L (11.9 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.

Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage the engine.

1. Park the machine on a level surface.

2. Using a clean rag, clean the area around the fuel tank cap.

3. Remove the cap from the fuel tank.

4. Fill the tank until the level is to the bottom of the filler neck with diesel fuel.

5. Install the fuel tank cap tightly after filling the tank.

   Note: If possible, fill the fuel tank after each use. This will minimize possible buildup of condensation inside the fuel tank.

The reservoir is filled at the factory with high-quality hydraulic fluid. Check the level of the hydraulic fluid before you first start the engine and daily thereafter; refer to Checking the Level of the Hydraulic Fluid .

Recommended replacement fluid: Toro PX Extended Life Hydraulic Fluid; available in 19 L (5 US gallon) pails or 208 L (55 US gallon) drums.

Note: A machine using the recommended replacement fluid requires less frequent fluid and filter changes.

Alternative fluids: If Toro PX Extended Life Hydraulic Fluid is not available, you may use another conventional, petroleum-based hydraulic fluid having specifications that fall within the listed range for all the following material properties and that it meets industry standards. Do not use synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product.

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

High Viscosity Index/Low Pour Point Anti-wear Hydraulic Fluid, ISO VG 46

Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic fluid is available in 20 ml (0.67 fl oz) bottles. A bottle is sufficient for 15 to 22 L (4 to 6 US gallons) of hydraulic fluid. Order Part No. 44-2500 from your authorized Toro distributor.

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

2. Check the sight level gauge on the side of the tank.

   Note: The level needs to be at the upper mark.

Do not operate the mower without first checking that the operator platform latching mechanism is fully engaged and in good working order.

Note: The engine shuts off if you leave the seat without engaging the parking brake.

Engine Start Lockout: You can start the engine only 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.

Engine Run Interlock: Once you start the engine, you must be seated before you disengage the parking brake for the engine to continue to run.

Cutting Unit Drive Lockout: The drive to the cutting units is only possible when you are seated. If you rise from the seat for a period of more than 1 second, a switch is activated and the drive to the cutting units is automatically disengaged. To engage the drive to the cutting units, you 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 you rise off the seat for a moment during normal work, drive to the cutting units is not affected.

You can start the engine only with the cutting unit drive switch in the OFF position.

Important: You must bleed the fuel system before starting the engine if you are starting the engine for the first time, the engine has shut off 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.

With all cutting units set at the same HOC via the indicator rings, you may notice 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 is influenced by the terrain, but you can achieve satisfactory results by setting the center cutting unit HOC indicator ring lower than the wing unit settings.

You can raise or lower the cutting units 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.

   Note: The cutting unit drive switch must be on (forward) to do this. The reel drive engages 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.

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

To activate the lift, press the Auto Limited Lift switch to the ON position (Figure 31).

To deactivate the lift, press the Auto Limited Lift switch to the OFF position (Figure 31).

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

Figure 31

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

The reel drive disengages immediately and the cutting units stop rising, 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 return to the floating position when returning to forward travel. The cutting units continue to rotate during this operation.

Reverse rotation cutting unit drive engagement: Press the bottom of the cutting unit drive switch to the reverse position (Figure 32).

All cutting unit drives disengagement: Set the switch to the middle position (Figure 32).

To lower the cutting units: The cutting unit drive switch must be set to forward. Operate the lift control switch(s) in a downward direction. The reel drives when the cutting units are approximately 150 mm (6 inches) above ground level.

1. Park the machine on a level surface, lower the cutting units to the ground or securely lock them in the designated transport positions, engage the parking brake, shut off the engine, and remove the key from the ignition switch.

2. Release all stored energy devices.

3. Check that all moving parts are stationary.

4. 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.

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

6. 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 33) as follows:

1. Release the valve locknut 1/2 turn counterclockwise and hold (Figure 33).

2. Rotate the valve hand wheel (Figure 33) counterclockwise to reduce weight transfer or clockwise to increase weight transfer.

3. Tighten the nut.

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 ceased running due to lack of fuel.

• Maintenance has been performed upon 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.

   Note: 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.

6. Operate the cutting unit drive switch to the OFF position and shut off the engine when the grinding action has stopped.

7. Thoroughly clean the blade edges and adjust the bedknives to the reels.

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.

You will need to grind the 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 should be carried out by your authorized Toro distributor on a quality, well-maintained reel/bedknife grinding machine
