    • 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.

  • Know how to stop the machine and shut off the engine quickly.

  • Do not operate the machine without all guards and other safety protective devices in place and functioning properly on the machine.

  • Before mowing, always inspect the machine to ensure that the cutting units are in good working condition.

  • Inspect the area where you will use the machine and remove all objects that the machine could throw.

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.

Fuel Specification

Use only clean, fresh diesel fuel with ultra low (<15 ppm) or low (<1000 ppm) sulfur content. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness.

Important: If you use high-sulfur diesel fuel (sulfur content 0.50 % (5000 ppm) to 1.0 % (10000 ppm), change the engine oil and oil filter every 75 hours.

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 a lower flash point and cold flow characteristics, which eases starting and reduces plugging of the fuel filter.

Using summer-grade fuel above -7°C (20°F) contributes toward longer fuel pump life and increased power compared to winter-grade fuel.

Biodiesel

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.

  • Biodiesel blends may damage painted surfaces.

  • Use B5 (biodiesel content of 5%) or lesser blends in cold weather.

  • Monitor seals, hoses, gaskets in contact with fuel as they may degrade over time.

  • The fuel filter may plug up for a period after converting to biodiesel blends.

  • Contact a distributor for more information on biodiesel blended fuel.

Filling the Fuel Tank

Fuel tank capacity: approximately 28 L (7.5 US gallons)

  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. Clean the area around the fuel-tank cap (Figure 46).

    • Wear appropriate clothing, including eye protection; long pants; substantial, slip-resistant footwear; and hearing protection. Tie back long hair and do not wear loose clothing or loose jewelry.

    • Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.

    • Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

    • Before you start the engine, ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position.

    • Do not carry passengers on the machine and keep bystanders and children out of the operating area.

    • Operate the machine only in good visibility to avoid holes or hidden hazards.

    • Avoid mowing on wet grass. Reduced traction could cause the machine to slide.

    • Keep your hands and feet away from the cutting units.

    • Look behind and down before backing up to be sure of a clear path.

    • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

    • Stop the cutting units whenever you are not mowing.

    • Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

    • Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is lethal if inhaled.

    • Do not leave a running machine unattended.

    • Before you leave the operator’s position, do the following:

      • 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.

    • Operate the machine only in good visibility and appropriate weather conditions. Do not operate the machine when there is the risk of lightning.

    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.

    Starting the Engine

    Note: You may need to bleed the fuel system if any of the following situations have occurred; refer to Bleeding the Fuel System:

    • It is the initial startup of a new engine.

    • The engine has shut off because lack of fuel.

    • You performed maintenance for the fuel system components, such as replacing the fuel filter.

    1. Ensure that the parking brake is engaged, and the reel drive switch is in the DISENGAGE position.

    2. Remove your foot from the traction pedal and ensure that the pedal is in the NEUTRAL position.

    3. Move the throttle lever to the 1/2 throttle position.

    4. Insert the key into the switch and rotate it to the ON/PREHEAT position until the glow plug indicator light goes out (approximately 7 seconds); then rotate the key to the START position to engage the starter motor. Release the key when the engine starts.

      Note: The key moves automatically to the ON/RUN position.

      Important: To prevent overheating of the starter motor, do not engage the starter longer than 15 seconds. After 10 seconds of continuous cranking, wait 60 seconds before engaging the starter motor again.

    5. When the engine is started for the first time or after an overhaul of the engine, operate the machine in forward and reverse for 1 to 2 minutes. Also operate the lift lever and cutting unit drive switch to ensure proper operation of all parts.

      Note: Turn the steering wheel to the left and right to check the steering response, then shut the engine off and check for oil leaks, loose parts, and any other wear or damage.

      Caution

      Checking for oil leaks, loose parts, and other malfunctions could result in injury.

      Shut off the engine and wait for all moving parts to stop before checking for oil leaks, loose parts, and other malfunctions.

    * Toro does not recommend this height of cut and/or mowing speed.

    Note: The higher the number, the higher the speed.

    Adjusting Reel Speed

    1. Verify the height-of-cut setting on the cutting units. Use the column of the Reel Speed Selection Chart listing either 5-blade, 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.

    2. Lift the cover from the control arm (Figure 48).

      g336520
    3. Turn the reel speed control knob (Figure 49) to the reel-speed number determined in Step 1.

      g011168
    4. Assemble the cover onto the control arm.

    5. 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

    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.

    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

    To prevent personal injury or damage to the machine, do not open or close the cutting unit shields while the engine is running.

    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.

    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 Safety

    Service Category

    ACEA—E6

    API—CH-4 or higher

    JASO—DH-2

    Preferred oil viscosity: SAE 15W-40 [-17ºC (above 0°F)]

    Alternate oil viscosity: 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.

    Checking the Engine-Oil Level

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the engine-oil level.
  • The engine is shipped with oil in the crankcase; however, check the oil level before and after you first start the engine.

    Note: Toro Premium Engine oil is available from a distributor in either 15W-40 or 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, you do not need to add oil.

    1. Prepare the machine for maintenance; refer to Preparing for Maintenance.

    2. Unlatch and open the hood.

To prevent the battery from freezing, ensure that it is fully charged. The specific gravity of a fully charged battery is 1.265 to 1.299.

    Troubleshooting

    Using the Standard Control Module (SCM)

    The Standard Control Module is a potted electronic device produced in a one-size-fits-all configuration. The module uses solid state and mechanical components to monitor and control standard electrical features required for safe product operation.

    The module monitors inputs including neutral, parking brake, PTO, start, backlap, and high temperature. The module energizes outputs including PTO, Starter, and ETR (energize to run) solenoid.

    The module is divided into inputs and outputs. Inputs and outputs are identified by green LED indicators mounted on the printed circuit board.

    The start circuit input is energized by 12 VDC. All other inputs are energized when the circuit is closed to ground. Each input has a LED that is illuminated when the specific circuit is energized. Use the input LEDs for switch and input circuit troubleshooting.

    Output circuits are energized by an appropriate set of input conditions. The 3 outputs include PTO, ETR, and START. Output LEDs monitor relay condition indicating the presence of voltage at 1 of 3 specific output terminals.

    Output circuits do not determine output device integrity, so electrical troubleshooting includes output LED inspection and conventional device and wire harness integrity testing. Measure the disconnected component impedance, the impedance through wire harness (disconnect at SCM), or by temporarily ”test energizing” the specific component.

    The SCM does not connect to an external computer or handheld device, cannot be re-programmed, and does not record intermittent fault troubleshooting data.

    The decal on the SCM only includes symbols. Three LED output symbols are shown in the output box. All other LEDs are inputs. The chart below identifies the symbols.

    g190826

    Here are the logical troubleshooting steps for the SCM device.

    1. Determine the output fault you are trying to resolve (PTO, START, or ETR).

    2. Move the key switch to the ON position and ensure that the red power LED is illuminated.

    3. Move all the input switches to ensure that all LEDs change state.

    4. Position the input devices at the appropriate position to achieve the appropriate output. Use the following logic chart to determine the appropriate input condition.

    5. If the specific output LED is illuminated without the appropriate output function, check the output harness, connections, and component. Repair as needed.

    6. If the specific output LED is not illuminated, check both fuses.

    7. If the specific output LED is not illuminated and the inputs are in the appropriate condition, install a new SCM and determine if the fault disappears.

    Each row (across) in the logic chart that follows identifies input and output requirements for each specific product function. The product functions are listed in the left column. The symbols identify the specific circuit condition including energized to voltage, closed to ground, and open to ground.

    • (–) Indicates a circuit closed to ground—LED ON.

    • (O) Indicates a circuit open to ground or de-energized—LED OFF.

    • (+) Indicates an energized circuit (clutch coil, solenoid, or start input)—LED ON.

    • A blank indicates a circuit that is not involved with the logic.

    To troubleshoot, turn on the key without starting the engine. Identify the specific function that does not work and work across the logic chart. Inspect the condition of each input LEDs to ensure that it matches the logic chart.

    If the input LEDs are correct, check the output LED. If the output LED is illuminated but the device is not energized, measure the available voltage at the output device, the continuity of the disconnected device, and the potential voltage on the ground circuit (floating ground). Repairs will vary depending on your findings.
