Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the working activity. Never assume that children will remain where you last saw them.
Keep children out of the working area and under the watchful care of another responsible adult, not the operator.
Be alert and turn the machine off if children enter the area.
Before and while backing or changing direction, look behind, down, and side-to-side for small children.
Never allow children to operate the machine.
Do Not carry children, even with the blades shut off. Children could fall off and be seriously injured or interfere with the safe operation of the machine. Children that have been given rides in the past could suddenly appear in the working area for another ride and be run over or backed over by the machine.
Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. The operator is responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, the operator must:
Review and understand the slope instructions in the manual and on the machine.
Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.
Operate across slopes, never up and down. Avoid operation on excessively steep or wet slopes.
Identify hazards at the base of the slope. Do not operate the machine near drop offs, ditches, embankments, water or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard. Use a walk behind machine or a hand held tool to operate in these areas.
Avoid starting, stopping or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.
Do not operate a machine under any conditions where traction, steering or stability is in question. 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. The machine can slide even if the drive wheels are stopped.
Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.
Use extra care while operating with accessories or attachments. These can change the stability of the machine and cause a loss of control. Follow directions for counter weights.
If you lose control of the machine, step off and away from the direction of travel of the machine.

Clean the machine as stated in the Maintenance section. Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas. These materials can become combustible and may result in a fire.
Frequently check for worn or deteriorating components that could create a hazard. Tighten loose hardware.
Machine weight: 460 kg (1,015 lb)
This machine does not have proper turn signals, lights, reflective markings, or a slow moving vehicle emblem. Driving on a street or roadway without such equipment is dangerous and can lead to accidents, causing personal injury. Driving on a street or roadway without such equipment may also be a violation of state laws, and you may be subject to traffic tickets and/or fines.
Do not drive the machine on a public street or roadway.
Loading the machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death.
Use extreme caution when operating a machine on a ramp.
Use only a single, full-width ramp; do not use individual ramps for each side of the machine.
If you must use individual ramps, use enough ramps to create an unbroken ramp surface wider than the machine.
Do not exceed a 15-degree angle between ramp and ground, or between a ramp, a trailer, or a truck.
Avoid sudden acceleration while driving machine up a ramp to avoid tipping backward.
Avoid sudden deceleration while backing machine down a ramp to avoid tipping backward.
Important: Do not attempt to turn the machine while on the ramp; you may lose control and drive off the side.
Use extreme caution when loading units onto trailers or trucks.
Use 1 full-width ramp that is wide enough to extend beyond the rear tires instead of individual ramps for each side of the machine (Figure 29). The platform, when down and locked into position, must extend back between the rear wheels and serves as a stop for tipping backward. Having a full-width ramp provides a surface for the platform to contact if the machine starts to tip backward. With the platform up, a full-width ramp provides a surface to walk on behind the machine.
The ramp should be long enough so that the angles do not exceed 15 degrees (Figure 29). A steeper angle may cause tine components to get caught, as the machine moves from ramp to trailer or truck. A steeper angle may also cause the machine to tip backward. If loading on or near a slope, position the trailer or truck so it is on the down side of the slope and the ramp extends up the slope. This minimizes the ramp angle. The trailer or truck should be as level as possible.
You should determine if it is best to have the platform up or down when loading, depending on conditions. If it is not possible to use 1 full-width ramp, use enough individual ramps to simulate a full-width, continuous ramp.
Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the machine to tip backward.
Use a heavy-duty trailer or truck to transport 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.
Raise the tines of the machine before driving onto the trailer or truck.
If using a trailer, connect it to the towing vehicle and connect the safety chains.
If applicable, connect the trailer brakes.
Load the machine onto the trailer or truck.
Shut off the engine, remove the key, engage the parking brake, and close the fuel valve.
Engage the parking brake and block the tires.
Use the tie-down points on the machine to securely bind the machine to the trailer or truck with straps, chains, cable, or ropes (Figure 30).
Note: Refer to your local ordinances for specific trailer and tie-down regulations.
While maintenance or adjustments are being made, someone could start the engine. Accidental starting of the engine could seriously injure you or other bystanders.
Remove the key from the ignition switch, engage parking brake, and pull the wire(s) off the spark plug(s) before you do any maintenance. Also push the wire(s) aside so it does not accidentally contact the spark plug(s).
Park machine on level ground, raise the tines, set parking brake, stop engine, remove key or disconnect spark plug wire. Wait for all movement to stop and allow the machine to cool before adjusting, cleaning or repairing. Never allow untrained personnel to service machine.
The engine can become very hot. Touching a hot engine can cause severe burns.
Allow the engine to cool completely before service or making repairs around the engine area.
Disconnect battery or remove spark plug wire before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last.
Keep the machine, guards, shields and all safety devices in place and in safe working condition. Frequently check for worn or deteriorating components and replace them with the manufacturer’s recommended parts when necessary.
Removal or modification of original equipment, parts and/or accessories may alter the warranty, controllability, and safety of the machine. Unauthorized modifications to the original equipment or failure to use original Toro parts could lead to serious injury or death. Unauthorized changes to the machine, engine, fuel or venting system, may violate applicable safety standards such as: ANSI, OSHA and NFPA and/or government regulations such as EPA and CARB.
Use care when checking and servicing tines. Wrap the tine(s) or wear gloves, and use caution when servicing them. Only replace damaged tines. Never straighten or weld them.
Use jack stands to support the machine and/or components when required.
Raising the machine for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the machine to fall, which could cause injury.
Do not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.
Carefully release pressure from components with stored energy.
Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.
If equipped, make sure all hydraulic fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to hydraulic system.
Keep body and hands away from pinhole leaks or nozzles that eject high pressure hydraulic fluid.
Use cardboard or paper, not your hands, to find hydraulic leaks.
Before performing any work on the hydraulic system:
– Safely relieve all pressure in the ground drive hydraulic system by placing the motion control levers in neutral and shutting off the engine.
– Safely relieve all pressure in the auxiliary hydraulic system by shutting off the engine, turning the ignition switch to the “ON” position, and pressing the tine ground engagement switch. Once the tines have lowered to the ground, release the tine ground engagement switch and turn the ignition switch to the “OFF” position.
Keep hands and feet away from moving parts. If possible, Do Not make adjustments with the engine running. If the maintenance or adjustment procedure require the engine to be running and components moving, use extreme caution.
Contact with moving parts or hot surfaces may cause personal injury.
Keep your fingers, hands, and clothing clear of rotating components and hot surfaces.
Check all bolts frequently to maintain proper tightness.
