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.
Operating the Choke Starting the Engine Use the choke to start a cold 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. 1. Pull up the choke knob to engage the choke before using the key switch (Figure 24). 2. Push down the choke knob to disengage the choke after the engine has started (Figure 24).
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 27 1. Motion-control lever—NEUTRAL-LOCK position 4. Backward 2. Center, unlocked position 5. Front of 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.
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 29). 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 30). 1. Move the transport lock to the lock position. 2.
Adjusting the Anti-Scalp Rollers 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 34 Adjust the anti-scalp rollers as shown in Figure 32, Figure 33, and Figure 34. 1. Anti-scalp roller 4. Flange nut 2. Spacer 5. Bolt 3.
Position B Use this position when bagging. Always align it with the blower opening. g027727 Figure 35 Positioning the Flow Baffle The following figures are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass. g005833 Figure 37 Note: If the engine power draws down and the mower ground speed is the same, open up the baffle. Position C Position A This is the full open 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. • Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills.
Selecting a Trailer WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death (Figure 41). • Use only a full-width ramp; do not use individual ramps for each side of the machine. • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck. g015123 • Ensure that the length of ramp is at least 4 times as long as the height of the trailer or truck bed to the ground.
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 41). 4. Back the machine up the ramp (Figure 42). g028043 Figure 42 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.
