Specifications Note: Specifications and design are subject to change without notice.
Operation • 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. Note: Determine the left and right sides of the machine from the normal operating position. • 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.
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.
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.
Testing the Safety-Interlock System Using the Safety-Interlock System Service Interval: Before each use or daily WARNING Test the safety-interlock system before you use the machine each time.

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.
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.
Starting the Engine Shutting Off the Engine Important: Do not engage 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. CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended. Note: You may need multiple attempts to start the engine the first time after adding fuel to an empty fuel system.
Using the Motion-Control Levers 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.
Driving Backward Using the Side Discharge 1. Move the levers to the center, unlocked position. 2. To go backward, slowly pull the motion-control levers rearward (Figure 28). Machines with Side Discharge Only 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.
Adjusting the Height of Cut Adjusting the Height-of-Cut Pin Using the Transport Lock 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. 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 29). 1. Move the transport lock to the lock position. 2.
Adjusting the Anti-Scalp Rollers For Machines with Side Discharge Whenever you change the height-of-cut, adjust the height of the anti-scalp rollers. 1. Park the machine on a level surface, disengage the blade-control switch, and engage the parking brake. 2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. g029957 Figure 33 Adjust the anti-scalp rollers as shown in Figure 31, Figure 32, and Figure 33. 1. Anti-scalp roller 4.
Adjusting the Skid(s) For Machines with Rear Discharge Mount the skids in the lower position when operating in height of cuts higher than 64 mm (2-1/2 inches) and in the higher position when operating in height of cuts lower than 64 mm (2-1/2 inches). Note: When the skids become worn, switch the skid to the opposite sides of the mower, flipping them over. This allows you to use the skids longer before replacing them. g024242 1.
Adjusting the Flow Baffle Cam Locks Positioning the Flow Baffle For Machines with Side Discharge For Machines with Side Discharge The following figures are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass. This procedure is applicable only to machines with the flow-baffle locks. Certain models have nuts and bolts in place of the flow-baffle locks and can be adjusted the same.
Position B Operating Tips Use this position when bagging. Always align it with the blower opening. 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.
Stopping the Machine Using the Fuel-Shutoff Valve If you must stop the forward motion of the machine while mowing, a clump of grass clippings may 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. The fuel-shutoff valve is located under the seat. Move the seat forward to access it. Close the fuel-shutoff valve for transport, maintenance, and storage.
Transporting the Machine The drive-wheel-release valves are located in the back of each hydraulic-drive unit, under the seat. 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 43). 4. Back the machine up the ramp (Figure 44). g028043 Figure 44 1. Back the machine up the ramp. 2. Drive the machine forward down the ramp. 5. Shut off the engine, remove the key, and engage the parking brake. 6.
