    Additional ROPS Safety for Machines with a Foldable Roll Bar

    • Keep a folding roll bar in the raised and locked position, and wear your seat belt when operating the machine with the roll bar in the raised position.

    • Lower a folding roll bar temporarily only when necessary. Do not wear the seat belt when the roll bar is folded down.

    • Be aware that there is no rollover protection when a folded roll bar is in the down position.

    • Check the area that you will be mowing and never fold down a folding roll bar in areas where there are slopes, drop-offs, or water.

    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 and 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. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.

    • 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 unit(s) lowered to the ground while operating on slopes. Raising the cutting unit(s) while operating on slopes can cause the machine to become unstable.

    • Use extreme caution with grass-collection systems or other attachments. These can change the stability of the machine and cause a loss of control.

    Operating the Parking Brake

    Always engage the parking brake when you stop the machine or leave it unattended.

    Engaging the Parking Brake

    Warning

    The parking brake may not hold the machine parked on a slope and could cause personal injury or property damage.

    Operating the Mower

    Using the Deck-Lift Switch

    The deck-lift switch raises and lowers the cutting unit (Figure 23). The engine must be running for you to use this lever.

    g020873
    • To lower the cutting unit, push the deck-lift switch down (Figure 23).

      Important: When you lower the cutting unit, it sets in a float/idle position.

    • To raise the mover deck, push the deck-lift switch up (Figure 23).

    Important: Do not continue to hold the switch up or down after the mower has fully raised or lowered. Doing so damages the hydraulic system.

    Engaging the Power Takeoff (PTO)

    The power-takeoff (PTO) switch starts and stops the mower blades and some powered attachments.

    Note: If the engine is cold, allow the engine to warm up 5 to 10 minutes before engaging the PTO.

    Adjusting the Height of Cut

    You can adjust the height of cut from 2.5 to 15.8 cm (1 to 6 inches) in 6 mm (1/4 inch) increments by relocating the stop pin into different hole locations.

    1. With the engine running, push the deck-lift switch up until the cutting unit is fully raised and release the switch immediately (Figure 23).

    2. Rotate the stop pin until the roll pin in it lines up with the slots in the holes in the height-of-cut bracket and remove it (Figure 26).

    3. Select a hole in the height-of-cut bracket corresponding to the height of cut desired, insert the pin, and rotate it down to lock it in place (Figure 26).

      Note: There are 4 rows of hole positions (Figure 26). The top row gives you the height of cut listed above the pin. The second row down gives you the height listed plus 6 mm (1/4 inch). The third row down gives you the height listed plus 12 mm (1/2 inch). The bottom row gives you the height listed plus 18 mm (3/4 inch). For the 15.8 cm (6 inch) position, there is only 1 hole, located in the second row. This does not add 6 mm (1/4 inch) to the 15.8 cm (6 inch) position.

      g020870
    4. Adjust the anti-scalp rollers and skids as required.

    Operating Tips

    Fast Throttle Setting/Ground Speed

    To maintain enough power for the machine and deck while mowing, operate the engine at the FAST throttle position and adjust your ground speed for conditions. Decrease the ground speed as the load on the cutting blades increase; increase the ground speed as the load on the blades decrease.

    Alternating the Mowing Direction

    Alternate your mowing direction to avoid making ruts in the turf, which can appear over time. This also helps to disperse clippings, which enhances decomposition and fertilization.

    Cutting Speed

    To improve cut quality, use a slower ground speed in certain conditions.

    Avoiding a Low Cut

    If the machine cutting width is wider than the machine that you previously used, raise the cutting height to ensure that uneven turf is not cut too short.

    Select the Proper Height-of-Cut Setting to Suit Conditions

    Remove approximately 25 mm (1 inch) or no more than 1/3 of the grass blade when cutting. In exceptionally lush and dense grass, you may need to slow down the forward speed and/or raise the height-of-cut to the next higher setting.

    Important: If you are cutting more than 1/3 of the grass blade, or are mowing in sparse long grass or dry conditions, use the flat sail of the blades to reduce air-borne chaff, debris, and strain on the deck-drive components.

    Cutting Long Grass

    If you allow the grass to grow slightly longer than normal, or if the grass contains a high degree of moisture, raise the cutting height to a higher setting and cut the grass at this setting. Then cut the grass again using the lower, normal setting.

    Keeping the Mower Clean

    Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality eventually becomes unsatisfactory.

    To reduce the risk of fire hazard, keep the engine, muffler, battery compartment, parking brake, cutting units, and fuel storage compartment free of grass, leaves, or excessive grease. Clean up any spilled oil or fuel.

    Maintaining the Blades

    • Maintain sharp blades throughout the cutting season. Sharp blades create a clean cut without tearing or shredding the grass blades. Tearing and shredding causes grass to turn brown at the edges, which slows growth and increases the chance of disease.

    • Check the blades daily for sharpness and for any wear or damage. Sharpen the blades as necessary.

    • If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade. Refer to the cutting unit Operator’s Manual for instructions to replace the blade.

    After Operation

    General Safety

    • Shut off the engine, remove the key, and wait for all movement to stop before you leave the operator’s position. Allow the machine to cool before adjusting, servicing, cleaning, or storing it.

    • Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills.

    • If the cutting units are in the transport position, use the positive mechanical lock (if available) before you leave the machine unattended.

    • Allow the engine to cool before storing the machine in any enclosure.

    • Remove the key and shut off the fuel (if equipped) before storing or hauling the machine.

    • Never 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.

    • Maintain and clean the seat belt(s) as necessary

    Pushing the Machine

    In an emergency, you can move the machine a very short distance by actuating the bypass valves in the hydraulic pump and pushing the machine.

    Important: Always push the machine by hand and never a long distance. Never tow the machine, because damage to the hydraulic system may occur.

    Important: The bypass valves must be open whenever you push or tow the machine. Close the valves once you have pushed or towed the machine to the desired location.

    1. Lift the seat; refer to Unlatching the Seat

    2. Locate the bypass valves (Figure 27) and rotate each bypass valve counterclockwise 1 turn.

      Note: This allows hydraulic fluid to bypass the pump, enabling the wheels to turn.

      Important: Do not rotate the bypass valves more than 1 turn. This prevents valves from coming out of the body and causing fluid to run out.

      g004644
    3. Ensure that the parking brake is disengaged and push the machine to the desired location.

    4. Close the valves by rotating each valve 1 clockwise turn (Figure 27).

      Note: Do not overtighten the valves.

    5. Torque the valves to approximately 8 N∙m (71 in-lb).

      Important: Ensure that the bypass valves are closed before you start the engine. Running the engine with open bypass valves causes the transmission to overheat.

    Hauling the Machine

    Use a heavy-duty trailer or truck to haul the machine. Ensure that the trailer or truck has all the necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.

    Warning

    Driving on the street or roadway without turn signals, lights, reflective markings, or a slow-moving-vehicle emblem is dangerous and can lead to accidents causing personal injury.

    Do not drive the machine on a public street or roadway.

    1. If you are using a trailer, connect it to the towing vehicle, and connect the safety chains.

    2. If applicable, connect the trailer brakes.

    3. Load the machine onto the trailer or truck; refer to Loading the Machine.

    4. Shut off the engine, remove the key, engage the parking brake, and close the fuel valve.

    5. Use the tie-down loops on the machine to securely fasten it to the trailer or truck with straps, chains, cable, or ropes (Figure 28).

      g191318

    Loading the Machine

    Use extreme caution when loading or unloading machines onto a trailer or a truck. Use a full-width ramp that is wider than the machine for this procedure. Drive the machine up ramps in reverse and drive it down ramps in a forward direction (Figure 29).

    g027995

    Important: Do not use narrow individual ramps for each side of the machine.

    Warning

    Loading the machine onto a trailer or truck increases the possibility of tipover and could cause serious injury or death.

    • Use extreme caution when operating a machine on a ramp.

    • When loading or unloading the machine, use the seat belt and ensure that the roll bar is in the raised position. Ensure that the roll bar can clear the top of an enclosed trailer.

    • Use only a full-width ramp; do not use individual ramps for each side of the machine.

    • Do not exceed a 15° angle between the ramp and the ground, or between the ramp and the trailer or truck.

    • Ensure that the ramp length is at least 4 times as long as the height of the trailer or truck bed to the ground. This ensures that the ramp angle does not exceed 15° on flat ground.

    • Drive the machine up ramps in reverse and drive it down ramps in a forward direction.

    • While driving the machine on a ramp, avoid sudden acceleration or deceleration, as this could cause a loss of control or a tipover situation.

    g027996

    Hydraulic System Maintenance

    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.

    Hydraulic Fluid Capacity

    The reservoir is approximately 4.7 liters (5 quarts).

    Hydraulic Fluid Specification

    The reservoir is filled at the factory with high-quality tractor transmission/hydraulic fluid. The recommended replacement fluid is as follows:

    Toro Premium Transmission/Hydraulic Tractor Fluid (Available in 19 L (5 gallon) pails or 208 L (55 gallon) drums. See the Parts Catalog or your Toro Distributor for part numbers).

    Alternate fluids: If the Toro fluid is not available, Mobil® 424 hydraulic fluid may be used.

    Note: Toro will not assume responsibility for damage caused by improper substitutions.

    Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 20 ml (2/3 fl oz) bottles. One 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.
