Performing Daily Maintenance

Maintenance Service IntervalMaintenance Procedure
Before each use or daily
  • Inspect the seat belt(s) for wear, cuts, and other damage. Replace the seat belt(s) if any component does not operate properly.
  • Before starting the machine each day, perform the Each Use/Daily procedures listed in .

    Filling the Fuel Tank

    Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 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.

    The fuel tank capacity is approximately 28 L (7.5 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. 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 Ready

    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.

    • Painted surfaces may be damaged by biodiesel blends.

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

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

    • Fuel filter plugging may be expected for a time after converting to biodiesel blends.

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

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

    • 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 the cutting unit(s) and lower the attachments.

      • Engage the parking brake.

      • Shut off the engine and remove the key (if equipped).

      • Wait for all movement to stop.

    • 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

    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 ceased running due to lack of fuel.

    • Maintenance has been performed upon the fuel system components; e.g., filter replaced, etc.

    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 noticeable malfunctions.

      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.

    Shutting Off the Engine

    Move the throttle control to the IDLE position, move the reel drive switch to DISENGAGE, and rotate the starter key to OFF.

    Note: Remove the key from the switch to prevent accidental starting.

    Bleeding the Fuel System

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

    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 (Figure 37).

      g008891
    5. Turn the key in the ignition switch to the ON position. The electric fuel pump begins operation, thereby forcing air out around the air bleed screw.

      Note: Leave the key in the ON position until a solid stream of fuel flows out around the screw.

    6. Tighten the screw and turn the key to off.

    Note: Normally the engine should start after following the bleeding procedures above. However, if the engine does not start, air may be trapped between the injection pump and the injectors; refer to Bleeding Air from the Injectors.

    Checking the Interlock System

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the interlock system.
  • Caution

    If the safety interlock switches are disconnected or damaged, the machine could operate unexpectedly, causing personal injury.

    • Do not tamper with the interlock switches.

    • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine.

    1. Ensure that all bystanders are away from the area of operation, and keep hands and feet away from the cutting units.

    2. While sitting on the seat, the engine must not start with either the cutting unit switch engaged or the traction pedal engaged. Correct the problem if it is not operating properly.

    3. While sitting on the seat, put the traction pedal in neutral, disengage the parking brake, and set the cutting unit switch in the OFF position. The engine should start. Rise from the seat and slowly press the traction pedal, and the engine should shut off in 1 to 3 seconds. Correct the problem if it is not operating properly.

    Note: The machine is equipped with an interlock switch on the parking brake. The engine shuts off if you press the traction pedal with the parking brake engaged.

    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 below 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 LED’s 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.

    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. The cutting units can also be shifted to vary tire tracking.

    • The cutting units tend to throw grass to the front or the rear of the machine. Front throw should be used when cutting smaller amounts of grass; thus, leaving a 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.

    After Mowing

    After mowing, thoroughly wash the machine with a garden hose without a nozzle to prevent excessive water pressure from prevent contamination and damage to the seals and bearings. Ensure that the radiator and oil cooler are kept free of dirt or grass clippings. After cleaning, inspect the machine for possible hydraulic fluid leaks, damage, or wear to the hydraulic and mechanical components. Check the cutting unit blades to ensure that they are sharp and that the reel-to-bedknife contact is properly adjusted.

    Important: After washing the machine, move the Sidewinder mechanism from left to right several times to remove the water between the bearing blocks and the cross tube (Model 03171 only).

    Selecting the Clip Rate (Reel Speed)

    To achieve a consistent, high quality of cut and a uniform after-cut appearance, it is important that the reel speed be matched to the height of cut.

    Important: If the reel speed is too slow, you may notice visible clip marks. If the reel speed is too fast, the cut may have a fuzzy appearance.

    12.7 mm1/2 inch9*9*99*88
    9.5 mm3/8 inch9*9*99*99

    Adjust the clip rate (reel speed) as follows:

    1. Verify the height-of-cut setting on the cutting units. Use the column of the chart listing either 5 or 8 reels, and find the height-of-cut listing nearest the actual height-of-cut setting. Look across the chart to find the number that corresponds to that height of cut.

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

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

    2. Turn the reel speed control knob (Figure 39) to the number setting determined in Step 1.

    3. 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 position indicated on the chart to account for differences in grass condition, grass length removed, and personal preference.

    The hood may be easily removed to ease maintenance procedures in the engine area of the machine.

    1. Unlatch and raise the hood.

    2. Remove the cotter pin that secures the hood pivot to the mounting brackets (Figure 42).

      g008908
    3. Slide the hood to the right side, lift the other side, and pull it out of the brackets.

    Note: Reverse the procedure to install the hood.

    Lubrication

    Greasing the Bearings And Bushings

    Maintenance Service IntervalMaintenance Procedure
    Every 50 hours
  • Lubricate all bearings and bushings(lubricate all bearings and bushings daily when conditions are dusty and dirty).
  • Every 500 hours
  • Grease the bearings in the rear axle.
  • The machine has grease fittings that must be lubricated regularly with No. 2 lithium grease. Lubricate the bearings and bushings daily when the operating conditions are extremely dusty and dirty. 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.

    The grease fitting locations and quantities are as follows:

    • Rear cutting unit pivot (Figure 43)

      g008894
    • Front cutting unit pivot (Figure 44)

      g008895

      g190872

    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 periodic inspections of bearing condition and seal integrity should be conducted to avoid downtime. These bearings should be inspected seasonally and replaced 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

    • Shut off the engine before checking the oil or adding oil to the crankcase.

    • Do not change the governor speed or overspeed the engine.

    Servicing the Air Cleaner

    Maintenance Service IntervalMaintenance Procedure
    Every 200 hours
  • Service the air cleaner(more frequently in extreme dusty or dirty conditions).
    • Check the air cleaner body for damage which could cause an air leak. Replace it if it is damaged. Check the whole intake system for leaks, damage, or loose hose clamps.

    • Service the air cleaner at the recommended service interval or earlier if engine performance suffers 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.

    • Ensure that the cover is seated correctly and seals with the air-cleaner body.

    1. Release the latches that secure the air-cleaner cover to the air-cleaner body (Figure 55).

      g027707
    2. Remove the cover from the air-cleaner body.

    3. Before removing the filter, use low-pressure air—276 kPa (40 psi), clean and dry—to help remove large accumulations of debris packed between the outside of primary filter and the canister. Avoid using high-pressure air which could force dirt through the filter into the intake tract. This cleaning process prevents debris from migrating into the intake when you remove the primary filter.

    4. Remove and replace the primary filter (Figure 56).

      Note: Cleaning the used element may damage the filter media.

      g008910
    5. Inspect the new filter for shipping damage and check the sealing end of the filter and the body. Do not use a damaged element.

    6. Insert the new filter by applying pressure to the outer rim of the element to seat it in the canister. Do not apply pressure to the flexible center of the filter.

    7. Clean the dirt ejection port located in the removable cover.

    8. Remove the rubber outlet valve from the cover, clean the cavity, and replace the outlet valve.

    9. Install the cover orienting the rubber outlet valve in a downward position—between approximately 5 o'clock to 7 o'clock when viewed from the end.

    10. Secure the cover latches.

    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, the oil level must be checked before and after the engine is first started.

    The crankcase capacity is approximately 3.8 L (4.0 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 -17ºC (0ºF))

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

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

    2. Remove the dipstick (Figure 57) and wipe it with a clean rag.

      g008881
    3. Push the dipstick down into the dipstick tube and ensure that it is seated fully, then pull the dipstick out and check the oil level.

    4. If the oil level is low, remove the oil-fill cap (Figure 58) and gradually add small quantities of oil, checking the level frequently, until the level reaches the Full mark on the dipstick.

      g008882
    5. Install the oil-fill cap and close the hood.

      Important: Keep the engine-oil level between the upper and lower limits on the oil gauge. Engine failure may occur as a result of overfilling or underfilling the engine oil.

    Changing the Engine Oil and the Filter

    Maintenance Service IntervalMaintenance Procedure
    After the first 50 hours
  • Change the oil and the oil filter.
  • Every 150 hours
  • Change the oil and the oil filter.
    1. Remove either drain plug (Figure 59) and let the oil flow into a drain pan; when the oil stops flowing, install the drain plug.

      g008911
    2. Remove the oil filter (Figure 60).

      g008912
