Key Switch Product Overview The key switch, used to start and shut off the engine, has 3 positions: OFF, RUN, and START . Refer to Starting the Engine (page 22). Throttle Control The throttle controls the engine speed, and there are 3 speeds: Maximum, Efficient, and Low. Refer to the Software Guide for more information. Blade-Control Switch (Power Takeoff) The blade-control switch, represented by a power-takeoff (PTO) symbol, engages and disengages power to the mower blades (Figure 5).
Horizon Display Monitor Refer to the Software Guide for more information. Refer to the Software Guide for detailed information explaining the operator interface that allows you to access information, reset counters, modify system settings, and troubleshoot the equipment. Alarm If an error occurs, an error message displays, the LED turns red, and the alarm sounds audibly as follows: • A fast chirp sound indicates critical errors.
Specifications Operation Note: Specifications and design are subject to Note: Determine the left and right sides of the machine from the normal operating position. change without notice.
Adding Fuel Fuel Safety • Fuel is extremely flammable and highly explosive. • • • • • • • • • A fire or explosion from fuel can burn you and others and can damage property. – To prevent a static charge from igniting the fuel, place the container and/or machine directly on the ground before filling, not in a vehicle or on an object. – Fill the fuel tank outdoors on level ground, in an open area, and when the engine is cold. Wipe up any fuel that spills.
Breaking in a New Machine Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel to expand. 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 to prevent the engine from starting unless: • The parking brake is engaged.
1. 2. Sit on the seat, engage the parking brake, and move the blade-control switch (PTO) to the OFF position. Move either motion-control lever out of the NEUTRAL-LOCK position. Try starting the engine; the engine should not start. Repeat for the other control lever. 3. Sit on the seat, engage the parking brake, move the blade-control switch (PTO) to the OFF position, and move the motion-control levers to the NEUTRAL-LOCK position. Now start the engine.
Changing the Seat Suspension • Keep your hands and feet away from the cutting units. Keep clear of the discharge opening. • Do not mow with the discharge deflector raised, removed, or altered unless there is a grass-collection system or mulch kit in place and working properly. The seat is adjustable to provide a smooth and comfortable ride. Position the seat where you are most comfortable.
• Replace damaged ROPS components. Do not • • g229846 Figure 13 • • 1. Wear hearing protection. • Clean grass and debris from the cutting unit, • • • • • • • • • • drives, muffler, and engine to help prevent fires. Start the engine with your feet well away from the blades. Be aware of the mower discharge path and direct the discharge away from others. Avoid discharging material against a wall or obstruction because the material may ricochet back toward you.
Operating the Parking Brake • 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. Always engage the parking brake when you stop the machine or leave it unattended. • 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.
Operating the Mower Starting the Engine Blade-Control Switch (PTO) Important: Do not engage the starter for more than 5 seconds at a time. If the engine fails to start, wait 15 seconds between attempts. Failure to follow these instructions can burn out the starter motor. The blade-control switch (PTO) starts and stops the mower blades and any powered attachments.
Using the Motion-Control Levers Shutting Off the Engine 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. g004532 Figure 21 1. Motion-control levers—NEUTRAL-LOCK position 4. Reverse 2. Center, unlocked position 5. Front of the machine 3. Forward Driving the Machine The drive wheels turn independently, powered by hydraulic motors on each axle.
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. Driving Forward Note: The engine shuts off when you move the traction-control with the parking brake engaged. To stop the machine, pull the motion-control levers to the NEUTRAL position. 1. Disengage the parking brake. 2. Move the motion-control levers to the center, unlocked position. 3.
Using the Side Discharge Adjusting the Height of Cut The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Using the Transport Lock The transport lock has 2 positions, and is used with the deck-lift pedal. There is a LOCK position and an UNLOCK position for the transport position of the mower deck (Figure 24).
Adjusting the Height-of-Cut Pin Adjusting the Anti-Scalp Rollers The height-of-cut is adjusted from 25 to 140 mm (1 to 5-1/2 inches) in 6 mm (1/4 inch) increments by relocating the clevis pin into different hole locations. 1. Move the transport lock to the lock position. 2. Push on the deck-lift pedal with your foot, and raise the mower deck to the transport position (also the 140 mm (5-1/2 inch) cutting height position) as shown in Figure 25. 3.
Adjusting the Flow Baffle Knob This procedure applies only to machines with the flow baffle knob. Certain models have nuts and bolts instead of the flow baffle knob that you can adjust the same way. You can adjust the mower discharge flow for different types of mowing conditions. Position the knob and baffle to give the best quality of cut. g029957 Figure 28 1. Anti-scalp roller 4. Flange nut 2. Spacer 5. Bolt 1.
Positioning the Flow Baffle The following figures are recommendations only. Adjustments vary by grass type, moisture content, and the height of the grass. Note: If the engine power draws down and the mower ground speed is the same, open the baffle. Position A This is the fully-rear position.
Operating Tips 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. 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.
Using the Drive-Wheel-Release Valves After Operation After Operation Safety General Safety WARNING Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury. • Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operator’s position. Allow the machine to cool before servicing, adjusting, fueling, cleaning, or storing it.
Transporting the Machine Use a heavy-duty trailer or truck to transport the machine. Use a full-width ramp. 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 or bystanders avoid injury. Refer to your local ordinances for trailer and tie-down requirements.
1. If using a trailer, connect it to the towing vehicle and connect the safety chains. 2. If applicable, connect the trailer brakes and lights. 3. Lower the ramp, ensuring that the angle between the ramp and the ground does not exceed 15 degrees (Figure 34). 4. Back the machine up the ramp (Figure 35). g028043 Figure 35 1.
