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 Roll Bar - Up 79.2 inches (201.2 cm) 79.2 inches (201.2 cm) Roll Bar - Down 80.9 inches (205.5 cm) 80.9 inches (205.
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. Wear safety glasses Note: Engaging the blade control switch (PTO) with the throttle position at half or less will cause excessive wear to the drive belts. 2.
Operating the Throttle Important: Do not engage starter for more than 5 seconds at a time. If the engine fails to start allow a 15 second cool-down period between attempts. Failure to follow these instructions can burn out the starter motor. The throttle control can be moved between Fast and Slow positions (Figure 15). Always use the fast position when turning on the mower deck with the blade control switch (PTO).

Positioning the Flow Baffle 2 1 The following figures are only recommendations for use. Adjustments will vary by grass type, moisture content, and height of grass. Note: If the engine power draws down and the mower ground speed is the same, open up the baffle. 4 3 Position A This is the full rear position. The suggested use for this position is a follows. G008961 Figure 31 1. Unlock lever 2. Rotate the cam lock to increase or decrease locking pressure • Use for short, light grass mowing conditions.
Position C This is the full open position. The suggested use for this position is as follows. • Use in tall, dense grass mowing conditions. • Use in wet conditions. • Lowers the engine power consumption. • Allows increased ground speed in heavy conditions. • This position is similar to the benefits of the Toro SFS mower.
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. 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 37). To adjust, move the lever sideways to unlock seat (Figure 35).
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. Stop the engine, remove the key, and allow all moving parts to stop before accessing the drive wheel release valves. WARNING The engine and hydraulic drive units can become very hot. Touching a hot engine or hydraulic drive units can cause severe burns.
Using the Side Discharge Transporting Machines The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 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.
Loading Machines Use extreme caution when loading units on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the unit (Figure 40). The lower rear section of the machine frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward.
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.

Checking for Bent Blades Servicing the Cutting Blades 1. Disengage the blade control switch (PTO), move the motion control levers to the neutral locked position and set the parking brake. Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. 2.
Removing the Blades 2. Check the balance of the blade by putting it on a blade balancer (Figure 97). If the blade stays in a horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off the end of the sail area only (Figure 98). Repeat this procedure until the blade is balanced. Blades must be replaced if a solid object is hit, if the blade is out of balance or is bent.
Removing the Mower Deck Installing the Blades 1. Install the blade onto the spindle shaft (Figure 98). Before servicing or removing the mower deck, the spring loaded deck arms must be locked out. Important: The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting. WARNING 2. Install the spring disk and blade bolt. The spring disk cone must be installed toward the bolt head (Figure 98). Torque the blade bolt to 85-110 ft-lb (115-150 N-m).
