Hour Meter Product Overview The hour meter records the number of hours the engine has operated. It operates when the engine is running. Use these times for scheduling regular maintenance (Figure 6). Fuel Gauge The fuel gauge is located with the hour meter and the bars light up when the ignition switch is on (Figure 6). The indicator light appears when the fuel level is low (approximately one gallon remaining in the fuel tank).
Blade Control Switch (PTO) Length: The blade control switch (PTO) is used to engage the electric clutch and drive the mower blades. Pull the switch up to engage the blades and release. To disengage the blades, push the blade control switch (PTO) down or move a motion control lever into the neutral lock position. Ignition Switch 48 inch Deck 52 inch Deck 60 inch Deck Roll Bar - Up 79.2 inches (201.2 cm) 79.2 inches (201.2 cm) 83.1 inches (211.1 cm) Roll Bar Down 80.9 inches (205.5 cm) 80.
Operation DANGER In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling.
Filling the Fuel Tank Breaking In a New Machine Note: Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the gasoline 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. 1. Park the machine on level ground. 2.
DANGER Operating on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. There is no rollover protection when the roll bar is down. Always keep the roll bar in the fully raised and locked position and use the seat belt. Read and follow the rollover protection instructions and warnings. To avoid loss of control and possibility of rollover: • Do not operate near drop-offs or near water.
Operating the Mower Blade Control Switch (PTO) The use of protective equipment for eyes, ears, feet and head is recommended. 1 2 The blade control switch (PTO) starts and stops the mower blades and any powered attachments. Engaging the Blade Control Switch (PTO) G009027 Figure 10 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 5-1/2 inch (140 mm) cutting height position) (Figure 27). 3. To adjust, rotate the pin 90 degrees and remove the pin from the height-of-cut bracket (Figure 27).
Adjusting the Flow Baffle Cam Locks Positioning the Flow Baffle The following figures are only recommendations for use. Adjustments will vary by grass type, moisture content, and height of grass. This procedure is applicable only to machines with the flow baffle locks. Certain models will have nuts and bolts in-place of the flow baffle locks and can be adjusted the same. Note: If the engine power draws down and the mower ground speed is the same, open up the baffle.
Using the Drive Wheel Release Valves Position C This is the full open position. The suggested use for this position is as follows. WARNING • Use in tall, dense grass mowing conditions. • Use in wet conditions. Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury. • Lowers the engine power consumption. • Allows increased ground speed in heavy conditions.
4. Rotate the release valve levers horizontally to run the machine (Figure 36). WARNING Using the Side Discharge Loading a unit onto a trailer or truck increases the possibility of backward tip-over and could cause serious injury or death. The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. • Use extreme caution when operating a unit on a ramp. • Ensure the ROPS is in the up position while using the seat belt when loading the machine.
Transporting Machines Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets or bystanders avoid injury. WARNING Driving on the street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury.
Operating Tips cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. Fast Throttle Setting When Stopping For best mowing and maximum air circulation, operate the engine at the fast throttle 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 by uncut grass.
