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. 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 Choke Use the choke to start a cold engine. 1. If the engine is cold, use the choke to start the engine. 2. Pull up on the choke knob to engage the choke before using the ignition switch (Figure 16). ST A RT N P RU ST 3. Push down on the choke to disengage the choke after the engine has started (Figure 16). O G008947 Figure 17 2. Turn the ignition key to stop to stop the engine. 1 Using the Fuel Shut-Off Valve The fuel shut-off valve is located under the seat.

Set the parking brake when you leave the machine; refer to Setting the Parking Brake in Operation. Remember to remove the key from the ignition switch. CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
Adjusting the Height-of-Cut Pin The height-of-cut is adjusted from 1 to 5-1/2 inches (25 to 140 mm) in 1/4 inch (6 mm) 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 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.
Unlatching the Seat • 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. g019755 Figure 36 1. Seat latch 2. Seat Changing the Seat Suspension The seat can be adjusted to provide a smooth and comfortable ride. Position the seat where you are most comfortable.
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.
