General Safety

Improperly using or maintaining this machine can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety-alert symbol Image, which means Caution, Warning, or Dangerpersonal safety instruction. Failure to comply with these instructions may result in personal injury or death.

Before Operation Safety

Fuel Safety
  • Use extreme care in handling fuel. It is flammable and its vapors are explosive.
  • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
  • Use only an approved fuel container.
  • Do not remove the fuel cap or fill the fuel tank while the engine is running or hot.
  • Do not add or drain fuel in an enclosed space.
  • 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 other appliance.
  • If you spill fuel, do not attempt to start the engine; avoid creating any source of ignition until the fuel vapors have dissipated.

During Operation Safety

Rollover Protection System (ROPS) Safety
  • Do not remove any of the ROPS components from the machine.
  • Ensure that the seat belt is attached and that you can release it quickly in an emergency.
  • Always wear your seat belt.
  • Check carefully for overhead obstructions and do not contact them.
  • Keep the ROPS in safe operating condition by thoroughly inspecting it periodically for damage and keeping all the mounting fasteners tight.
  • Replace all damaged ROPS components. Do not repair or alter them.
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

Maintenance Safety

Engine Safety
  • Shut off the engine before checking the oil or adding oil to the crankcase.
  • Do not change the governor speed or overspeed the engine.
Electrical System Safety
  • Disconnect the battery before repairing the machine. Disconnect the negative terminal first and the positive last. Connect the positive terminal first and the negative last.
  • Charge the battery in an open, well-ventilated area, away from sparks and flames. Unplug the charger before connecting or disconnecting the battery. Wear protective clothing and use insulated tools.
Cooling System Safety
  • Swallowing engine coolant can cause poisoning; keep out of reach from children and pets.
  • Discharge of hot, pressurized coolant or touching a hot radiator and surrounding parts can cause severe burns.
    • Always allow the engine to cool at least 15 minutes before removing the radiator cap.
    • Use a rag when opening the radiator cap, and open the cap slowly to allow steam to escape.
Hydraulic System Safety
  • Seek immediate medical attention if fluid is injected into skin. Injected fluid must be surgically removed within a few hours by a doctor.
  • Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.
  • Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.
  • Use cardboard or paper to find hydraulic leaks.
  • Safely relieve all pressure in the hydraulic system before performing any work on the hydraulic system.
Blade Safety
  • A worn or damaged blade or bedknife can break, and a piece could be thrown toward you or bystanders, resulting in serious personal injury or death.
  • Inspect the blades and bedknives periodically for excessive wear or damage.
  • Use care when checking the blades. Wear gloves and use caution when servicing them. Only replace or backlap the blades and bedknives; never straighten or weld them.
  • On machines with multiple cutting units, take care when rotating a cutting unit; it can cause the reels in the other cutting units to rotate.

  6. 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
    Graphic
    G411275
  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. Ensure that the fuel tank is at least half full.
  3. Unlatch and raise the hood.
  4. Open the air-bleed screw on the fuel-injection pump.
  5. Turn the ignition key to the On position.
    Note: The electric fuel pump runs, forcing air out around the air-bleed screw.
  6. 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

  1. Wash the machine and grease it.

Lubrication

Greasing the Bearings and Bushings
The machine has grease fittings that must be lubricated regularly. Dusty and dirty operating conditions could cause dirt to get into the bearings and bushings, resulting in accelerated wear. Lubricate the grease fittings immediately after every washing, regardless of the interval specified.
  1. Prepare the machine for maintenance.
  2. Grease all machine fittings with No. 2 lithium grease.

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.

Engine Maintenance

Engine Oil Specifications
Oil Type
Use high-quality, low-ash engine oil that meets or exceeds API service category CH-4 or higher.
Use the following engine oil viscosity grade:
  • Preferred oil: SAE 15W-40 [-17°C (above 0°F)]
  • Alternate oil: SAE 10W-30 or 5W-30 (all temperatures)
Toro Premium Engine Oil is available from your authorized Toro distributor in either 15W-40 or 10W-30 viscosity grades.
Crankcase Capacity
Approximately 3.8 L (4.0 US qt) with the filter
Checking the Engine-Oil Level
Note: Check the oil when the engine is cool. If the engine is warm, wait 10 minutes before checking.
If the oil level is below the lower limit mark on the dipstick, add oil gradually until the level reaches the upper limit mark on the dipstick.
Important  
Keep the engine-oil level between the upper and lower limits on the dipstick. Overfilling or underfilling the engine oil may cause severe engine damage.
 
  1. Prepare the machine for maintenance.
  2. Graphic
    G453109
  3. Open the hood.
  4. Check the level of the engine oil.
  5. Close and latch the hood.
Changing the Engine Oil and Filter
  1. Prepare the machine for maintenance.
  2. Unlatch and open the hood.
  3. Perform the following steps to change the engine oil:
    1. Remove either drain plug and allow all of the existing oil to drain out of the engine.
    2. Install the drain plug.

  6. Close and latch the hood.
Servicing the Air Cleaner
  • Check the whole intake system for leaks, damage, or loose hose clamps. Do not use a damaged air filter.
  • Service the air-cleaner filter at the recommended service interval or earlier if engine performance declines due to extremely dusty, dirty conditions. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed.
Important  
Ensure that the cover is seated correctly, seals with the air-cleaner body, and the rubber outlet valve is in a downward positionbetween the 5 oclock and 7 oclock positions when viewed from the end.

Fuel System Maintenance

This Operators Manual contains more detailed fuel and fuel system maintenance information than the engine Owners 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 todays 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
  1. Prepare the machine for maintenance.
  2. Drain and clean the tank if the fuel system becomes contaminated or if the machine will be stored for an extended period. Use clean fuel to flush out the tank.
Inspecting the Fuel Lines and Connections
  1. Prepare the machine for maintenance.
  2. Unlatch and open the hood.
  3. Inspect the fuel lines and fittings for deterioration, damage, or loose connections.
    Note: Repair or replace any damaged or worn the fuel lines or fittings.
  4. Close and latch the hood.
Servicing the Fuel/Water Separator
Draining the Fuel/Water Separator
  1. Prepare the machine for maintenance.
  2. Drain the water separator as shown.
