Specifications Note: Specifications and design are subject to change without notice.
Fuel Safety Operation • Fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. Note: Determine the left and right sides of the machine from the normal operating position. – To prevent a static charge from igniting the fuel, remove the machine from the truck or trailer and refuel it on the ground, away from all vehicles.
Adding Fuel Note: Do not fill the fuel tank completely full. The empty space in the tank allows the fuel to expand. 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.
Using the Rollover-Protection System (ROPS) WARNING To avoid injury or death from rollover, keep the roll bar in the fully raised, locked position and use the seat belt. Ensure that the seat is secured to the machine. WARNING There is no rollover protection when the roll bar is in the down position. • Lower the roll bar only when absolutely necessary. • Do not wear the seat belt when the roll bar is in the down position. • Drive slowly and carefully. • Raise the roll bar as soon as clearance permits.
Using the Safety-Interlock System Test the safety-interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately. 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.
Positioning the Seat Changing the Seat Suspension The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable (Figure 10). The seat is adjustable to provide a smooth and comfortable ride. Position the seat where you are most comfortable. To adjust it, turn the knob in front either direction to provide the best comfort (Figure 12).
• 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. • Do not mow in reverse unless it is absolutely necessary. Always look down and behind you before moving the machine in reverse. g229846 Figure 13 • Use extreme care when approaching blind 1. Wear hearing protection. corners, shrubs, trees, or other objects that may block your view.

The machine can slide even if the drive wheels are stopped. repair or alter them. • There is no rollover protection when the roll bar • Remove or mark obstacles such as ditches, holes, is down. ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine. • Wheels dropping over edges, over steep banks, or into water can cause a rollover, which may result in serious injury or death.
Operating the Parking Brake Operating the Mower Blade-Control Switch (PTO) Always engage the parking brake when you stop the machine or leave it unattended. The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. Engaging the Parking Brake Engaging the Blade-Control Switch (PTO) Park the machine on a level surface. Note: Engaging the blade-control switch (PTO) with the throttle position at half or less causes excessive wear to the drive belts.
Operating the Choke Use the choke to start a cold engine. 1. Pull up the choke knob to engage the choke before using the key switch (Figure 20). 2. Push down the choke knob to disengage the choke after the engine has started (Figure 20). g032328 g008959 Figure 21 Figure 20 1. ON position 2. OFF position Starting the Engine 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.
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 23 1. Motion-control levers—NEUTRAL-LOCK position 4. Reverse 2. Center, unlocked position 5. Front of the machine 3.
Driving the Machine The drive wheels turn independently, powered by hydraulic motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require some time for you to adapt to how it moves. The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the FAST position for best performance.
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 26).
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 inches) cutting height position) as shown in Figure 27. 3.
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. The suggested use for this position is as follows: g029957 Figure 30 1. Anti-scalp roller 4. Flange nut 2. Spacer 5. Bolt • Short, light grass mowing conditions • Dry conditions • Smaller grass clippings 3.
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.
After Operation 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. After Operation Safety Keeping the Underside of the Mower Deck Clean General Safety 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.
Using the Drive-Wheel-Release Valves 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 allow all moving parts to stop before accessing the drive-wheel-release valves. g015123 Figure 35 1. Vertical to push the machine WARNING The engine and hydraulic-drive units can become very hot. Touching a hot engine or hydraulic-drive units can cause severe burns. 5.
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.
