Operation
Note: Determine the left and right sides of the machine from the normal operating position.
Before Operation
Before Operation Safety
General Safety
· Never allow children or untrained people to operate or service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.
· Become familiar with the safe operation of the equipment, operator controls, and safety signs.
· Know how to stop the machine and shut off the engine quickly.
· Check that operator-presence controls, safety switches, and shields are attached and functioning properly. Do not operate the machine unless they are functioning properly.
· Before mowing, always inspect the machine to ensure that the blades, blade bolts, and cutting assemblies are in good working condition. Replace worn or damaged blades and bolts in sets to preserve balance.
· Inspect the area where you will use the machine and remove all objects that the machine could throw.
· Evaluate the terrain to determine the appropriate equipment and any attachments or accessories required to operate the machine properly and safely.
Fuel Safety
· To avoid personal injury or property damage, use extreme care in handling fuel. Fuel vapors are flammable and explosive.
· Extinguish all cigarettes, cigars, pipes, and other sources of ignition.
· Use only an approved fuel container. · Do not remove the fuel cap or add fuel to the fuel
tank while the engine is running or while hot. · Do not refuel the machine indoors. · 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 on other appliances. · Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place

containers on the ground, away from your vehicle before filling.
· Remove the equipment from the truck or trailer and refuel it while it is on the ground. If this is not possible, then refuel from a portable container rather than a fuel-dispenser nozzle.
· Do not operate the machine without the entire exhaust system in place and in proper working condition.
· Keep the fuel-dispenser nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
· If you spill fuel on your clothing, change your clothing immediately. Wipe up any fuel that spills.
· Never overfill the fuel tank. Replace the fuel cap and tighten it securely.
· Store fuel in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of fuel.
· Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows fuel to expand.
­ Avoid prolonged breathing of vapors.
­ Keep your face away from the nozzle and fuel tank opening.
­ Avoid contact with skin; wash off spills with soap and water.
Adding Fuel
Recommended Fuel
· For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
· Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.
· Do not use gasoline containing methanol.

13

Search

· Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.
· Do not add oil to gasoline.

Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide the following benefits: · Keeps fuel fresh during storage of 90 days or less
(drain the fuel tank when storing the machine for more than 90 days) · Cleans the engine while it runs · Eliminates gum-like varnish buildup in the fuel system, which causes hard starting
Important: Do not use fuel additives containing methanol or ethanol. Add the correct amount of fuel stabilizer/conditioner to the fuel.
Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.
Filling the Fuel Tank
1. Park the machine on a level surface.
2. Engage the parking brake.
3. Shut off the engine and remove the key.
4. Clean around the fuel-tank cap.
5. Fill the fuel tank to the bottom of the filler neck (Figure 8).
Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel to expand.

Figure 8

g027243

Performing Daily Maintenance
Before starting the machine each day, perform the Each Use/Daily procedures listed in Maintenance (page 26).
Breaking in a New Machine
New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance.

Using the Safety-Interlock System
WARNING
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.
Understanding the Safety-Interlock System
The safety-interlock system is designed for the following: · To prevent the engine from starting unless the
traction pedal is in the NEUTRAL position. · To automatically ensure that the parking brake
is engaged and the PTO is off when starting the machine. · To shut off the engine whenever the traction pedal is not in the NEUTRAL position and you rise from the seat. · To automatically engage the parking brake and disengage the PTO, when you rise out of the seat with the traction pedal in the NEUTRAL position. · To shut off the engine whenever the parking brake is not engaged and you rise from the seat.
Testing the Safety-Interlock System
1. Sit in the seat with the engine off and ensure that the PTO switch is in the OFF position.
2. Turn the key switch to the START position; the starter should crank. Do not start or shut off the engine prior to step 3.
3. Turn the key switch to the ON position and push the Smart Park switch to the OFF position. The brake should disengage and the brake light should turn off.
4. With the brake disengaged and traction pedal in the NEUTRAL position, turn the key to the START position. The brake should automatically engage, the engine should crank, and the brake light should turn on.
5. With the engine off and the key in the ON position, engage the PTO by pulling up the

blade-control switch; you should hear the clutch engage.
6. Ensure that the traction pedal is in neutral and turn the key to the START position. The PTO should disengage and the engine should crank and start without the blades moving.

Slope Safety
· 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, do the following:
­ Review and understand the slope instructions in the manual and on the machine.
­ Use an angle indicator to determine the approximate slope angle of the area.
­ Never operate on slopes greater than 15 degrees.
­ 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.

· 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 trimmer to mow the grass 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, such as grass-collection systems. These can change the stability of the machine and cause a loss of control. Follow directions for counterweights.
· If possible, keep the deck lowered to the ground while operating on slopes. Raising the deck while operating on slopes can cause the machine to become unstable.

Towing Safety
· Do not attach towed equipment except at the hitch point.
· Follow the attachment manufacturer’s recommendation for weight limits for towed equipment and towing on slopes. Towed weight must not exceed the weight of the machine, operator, and ballast. Use counterweights or wheel weights as described in the attachment, or in towing the machine Operator’s Manual.
· Never allow children or others in or on the towed equipment.
· On slopes, the weight of the towed equipment may cause loss of traction, increased risk of rollover, and loss of control. Reduce the towed weight and slow down.
· The stopping distance increases with the weight of a towed load. Travel slowly and allow extra distance to stop.
· Make wide turns to keep the attachment clear of the machine.

Starting the Engine
Important: Do not engage the starter for more than 5 seconds at a time. Engaging the starter motor for more than 5 seconds can damage the starter motor. If the engine fails to start, wait 10 seconds before operating the engine starter again.
Note: It may be necessary to hold the lever against the stop, in the choke position, while trying to start the engine (Figure 17).

CAUTION
Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
Always remove the key and engage the parking brake when leaving the machine unattended.
Driving the Machine
This machine has the characteristics of both a garden tractor and a zero-turn machine. Like a garden tractor, the machine has a foot pedal that controls the forward and reverse motion along with the speed, and it has a steering wheel that controls the direction and the turning radius. Like a zero-turn machine, the rear drive wheels operate independently of each other, enabling you to make sharp turns and to turn in different directions quickly. These characteristics vastly improve the maneuverability of the machine, but they may also require you to practice driving if you are unfamiliar with this type of machine.

WARNING
The machine can spin very rapidly. You may lose control of the machine and cause personal injury or damage to the machine. · Use caution when making turns. · Slow the machine down before making
sharp turns.

Figure 17

g027899

Shutting Off the Engine
1. Disengage the blades by moving the blade-control switch to the OFF position (Figure 17).
2. Engage the parking brake; refer to Operating the Smart ParkTM Parking Brake (page 19).
3. Move the throttle control to the FAST position.
4. Turn the key to the OFF position and remove the key.

The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Placing the throttle control in the FAST position can be best for performance. For most applications, operating in the FULL- THROTTLE position is desirable.
Driving Forward or Backward
1. Move the throttle to the FAST position.
2. Release the parking brake.
3. Place your foot onto the traction-control pedal and slowly press the top of the pedal to go forward, or press on the bottom of the pedal to move backward (Figure 18).
Note: The farther you move the pedal in either direction, the faster the machine moves in that direction.

Mowing in Reverse
The machine has an interlock feature that prevents the mower deck from mowing while the machine is traveling in reverse. If you shift into reverse with the PTO engaged, the PTO stops. If you need to mow while in reverse gear, you can temporarily deactivate this interlock.
Note: Do not mow while backing up unless it is necessary.
DANGER
A child or bystander could be backed over by a riding mower with blades engaged and cause serious personal injury or death.
· Do not mow in reverse unless absolutely necessary.
· Always look backward and down before backing up.
· Use the Key Choice switch only if you are certain no children or other bystanders will appear in the mowing area.
· Always remove both the ignition and Key Choice keys and put them in a safe place out of the reach of children or unauthorized users when leaving the machine unattended.
If you are certain that you can safely mow or operate an attachment in reverse, complete the following procedure:
1. Insert the Key Choice key into the Key Choice switch (Figure 7).
2. Engage the PTO.

3. Turn the Key Choice key clockwise until it stops and release it.
Note: A red light illuminating on the console indicates that the interlock has been deactivated.
4. Perform the mowing.
5. When finished mowing, remove the Key Choice key (Figure 7).
Note: Once you deactivate the interlock, it stays in this mode–with your mower blade or PTO powered attachment operating whenever you back up–and the console light stays on until you either disengage the PTO or shut off the engine.
Using the Side Discharge
The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.
DANGER
Without a grass deflector, discharge cover, or a complete grass-catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. · Never remove the grass deflector from the
mower deck because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately. · Never put your hands or feet under the mower deck. · Never try to clear the discharge area or mower blades unless you move the blade-control switch (PTO) to the OFF position, rotate the key switch to the OFF position, and remove the key from the key switch. · Make sure that the grass deflector is in the down position.

Adjusting the Height of Cut
Note: The transport position is the highest height-of-cut position or cutting height at 115 mm (4-1/2 inches) as shown in Figure 19.
Height of cut is controlled by the lever located to the right of the operating position (Figure 19).

Operating Tips
Using the Fast Throttle Setting
For best mowing and maximum air circulation, operate the engine at the FAST position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower deck in uncut grass. Always try to have 1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower deck.

Cutting a Lawn for the First Time
Cut grass slightly longer than normal to ensure that the cutting height of the mower deck does not scalp any uneven ground. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than 15 cm (6 inches) tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.

Cutting a Third of the Grass Blade
It is best to cut only about a third of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.

Alternating the Mowing Direction
Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.

Figure 19

Mowing at Correct Intervals
g028025 Grass grows at different rates at different times of the year. To maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height, then mow again 2 days later at a lower height setting.

Using a Slower Cutting Speed
To improve cut quality, use a slower ground speed in certain conditions.

Avoiding Cutting Too Low
When mowing uneven turf, raise the cutting height to avoid scalping the turf.

Stopping the Machine
If you must stop the forward motion of the machine while mowing, a clump of grass clippings may

22

Search

drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or you can disengage the mower deck while moving forward.
Keeping the Underside of the Mower Deck Clean
Clean clippings and dirt from the underside of the mower deck after each use. If grass and dirt build up inside the mower deck, cutting quality will eventually become unsatisfactory.
Maintaining the Blade(s)
Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the mower blades after each use for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade.

After Operation
After Operation Safety
