Slope Safety

Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution.
Evaluate the site conditions to determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.
Review the slope instructions, listed below, for operating the machine on slopes. Before you operate the machine, review the site conditions to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.
- Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.
- Do not operate a machine under any conditions where traction, steering, or stability is in question.
- Remove or mark obstructions such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstructions. Uneven terrain could overturn the machine.
- Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction.
- Use extreme caution when operating the machine near drop-offs, ditches, embankments, water hazards, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard.
- Identify hazards at the base of the slope. If there are hazards, mow the slope with a pedestrian-controlled machine.
- If possible, keep the cutting units lowered to the ground while operating on slopes. Raising the cutting units while operating on slopes can cause the machine to become unstable.

This triplex mower has a unique drive system for superior traction on hills. The uphill wheel does not spin out and limit traction like conventional triplex mowers. If you operate the machine on a side hill that is too steep, rollover will occur before losing traction.

When possible, mow up and down a hill rather than across it.
On side hills, shift the cutting units uphill (if equipped).
If the tires lose traction, disengage the blade(s) and proceed slowly straight down the slope.
If you must turn, turn slowly and gradually downhill, if possible.

After Operation Safety

Park the machine on a level surface.
Disengage and lower the cutting units
Engage the parking brake.
Shut off the engine and remove the key.
Wait for all movement to stop.
Allow the machine to cool before adjusting, servicing, cleaning, or storing it.
To help prevent fires, ensure that the cutting units, drives, mufflers, cooling screens, and engine compartment are free from grass and debris buildup. Clean up oil or fuel spills.
Disengage the drive to the attachment whenever you are hauling or not using the machine.
Maintain and clean the seat belt(s) as necessary.
Do not store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or on other appliances.

Adjusting the Reel Speed

G411273

Verify the height-of-cut setting on the cutting units. Use the column of the Reel Speed Selection Chart listing either 8-blade or 11-blade reels, and find the height-of-cut listing nearest the actual height-of-cut setting. Look across the chart to find the reel-speed number that corresponds to that height-of-cut.
Lift the cover from the control arm.

G411274

Turn the reel-speed-control knob to the reel-speed number determined in Step 1.
Install the cover on the control arm.
Operate the machine for several days, then examine the cut to ensure the quality-of-cut. The reel speed knob may be set 1 position on either side of the reel-speed number indicated on the chart to account for differences in grass condition, grass length removed, and personal preference.

Bleeding the Fuel System

G411275

Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.
Ensure that the fuel tank is at least half full.
Unlatch and raise the hood.
Open the air-bleed screw on the fuel-injection pump.
Turn the ignition key to the On position.

Note: The electric fuel pump runs, forcing air out around the air-bleed screw.
Tighten the screw and turn the ignition key to the Off position.

Note: The engine should start after you follow this procedure. If the engine does not start, you may need to bleed air from the injectors.

Operating Tips

Mowing Techniques

To begin cutting, engage the cutting units, then approach the mowing area slowly. Once the front cutting units are over the mowing area, lower the cutting units.
To achieve the professional straight-line cut and striping that is desirable for some applications, find a tree or other object in the distance and drive straight toward it.
As soon as the front cutting units reach the edge of the mowing area, lift the cutting units and perform a tear drop shaped turn to quickly line you up for your next pass.
To mow around bunkers, ponds, or other contours easily, use the Sidewinder and move the control lever left or right, depending on your mowing application. You can also shift the cutting units to vary tire tracking.
The cutting units tend to throw grass to the front or the rear of the machine. Front throw grass clippings when cutting smaller amounts of grass, which produces better after-cut appearance. To throw clippings to the front, simply close the rear shield on the cutting units.

Caution

Opening or closing the cutting unit shields while the engine is running could result in minor or moderate injury.

Shut off the engine and wait for all moving parts to stop before opening or closing the cutting unit shields.

When cutting larger amounts of grass, position the shields to just below horizontal. Do not open the shields too far or an excessive amount of clippings could build up on the frame, rear radiator screen, and engine area.
The cutting units are also equipped with balance weights on the non-motor end to give an even cut. You can add or remove weights if a mismatch occurs on your turf.

After Operation

After Mowing

Wash the machine and grease it.

Towing the Machine

In case of an emergency, you can tow the machine for a short distance; however, Toro does not recommend this as a standard procedure.

Important

Do not tow the machine faster than 3 to 4 km/h (2 to 3 mph) because it may damage the drive system. If you must move the machine a considerable distance, transport it on a truck or trailer.

Open the hood.

G413470

Near the right hood latch, rotate the handle-bypass valve on the pump 90° (1/4 turn).
Close and latch the hood.
Connect the tow vehicle to the machine at the tie-down points.
Sit in the operator’s seat, and if needed, use the parking brake to control your machine while being towed.

Important

Do not start the engine while the bypass valve is open.
Before starting the engine, close the bypass valve by rotating it 90° (1/4 turn).

Checking the Sealed Bearings

Bearings rarely fail from defects in materials or workmanship. The most common reason for failure is moisture and contamination working its way past the protective seals. Bearings that are greased rely upon regular maintenance to purge harmful debris from the bearing area. Sealed bearings rely on an initial fill of special grease and a robust integral seal to keep contaminants and moisture out of the rolling elements.

The sealed bearings require no lubrication or short-term maintenance. This minimizes routine service required and reduces the potential of turf damage due to grease contamination. These sealed bearing packages will provide good performance and life under normal use, but you should periodically inspect the bearing condition and seal integrity to avoid downtime. Inspect the bearings seasonally and replace the them if they are damaged or worn. Bearings should operate smoothly with no detrimental characteristics such as high heat, noise, looseness, or indications of corrosion (rust).

Due to the operating conditions these bearing/seal packages are subject to (i.e., sand, turf chemicals, water, impacts, etc.) they are considered normal wear items. Bearings that fail due to causes other than defects in materials or workmanship are typically not covered under the warranty.

Note: Bearing life can be negatively affected by improper wash-down procedures. Do not wash down the machine when it is still hot and avoid directing high-pressure or high-volume spray at the bearings.

Fuel System Maintenance

This Operator’s Manual contains more detailed fuel and fuel system maintenance information than the engine Owner’s Manual, which is a general-purpose reference relating to fuel and fuel maintenance.

Ensure that you understand that the fuel system maintenance, fuel storage, and fuel quality require your attention to avoid downtime and extensive engine repairs.

The fuel system has extremely tight tolerances due to the emissions and control requirements. Diesel fuel quality and cleanliness is more important for the longevity of today’s high-pressure common rail (HPCR) fuel-injection system used on diesel engines.

Important

Water or air in the fuel system will damage your engine! Do not assume that new fuel is clean. Ensure that your fuel is from a quality supplier, store your fuel correctly, and use your fuel supply within 180 days.

Important

If you do not follow the procedures for fuel filter replacement, fuel system maintenance, and fuel storage, the engine fuel system could fail prematurely. Perform all fuel system maintenance at the specified intervals or whenever the fuel is contaminated or its quality is poor.

Fuel Storage

Appropriate fuel storage is critical for your engine. Proper maintenance of fuel storage tanks is often overlooked and leads to the contamination of fuel delivered to the machine.

Acquire only enough fuel that you will consume within 180 days. Do not use fuel that has been stored for more than 180 days. This helps eliminate water and other contaminates in the fuel.
If you do not remove the water from the storage tank or machine fuel tank, it can lead to rust or contamination in the storage tank and fuel system components. Tank sludge developed by mold, bacteria, or fungus restricts flow and clogs the filter and fuel injectors.
Inspect your fuel storage tank and machine fuel tank regularly to monitor the fuel quality in the tank.
Ensure that your fuel comes from a quality supplier.
If you find water or contaminants in your storage tank or machine fuel tank, work with your fuel provider to correct the problem and perform all fuel system maintenance.
Do not store diesel fuel in tanks or canisters made with zinc-plated components.

Servicing the Fuel Tank
