Product Overview 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). Safety Interlock Indicators There are symbols on the hour meter and the indicate with a black triangle that the interlock component is in the correct position (Figure 6).
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.
Breaking In a New Machine Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. 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.
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 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.
CAUTION 1 This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. 2 Wear hearing protection when operating this machine. The use of protective equipment for eyes, ears, feet and head is recommended. 1 3 2 G008944 G009027 Figure 12 Figure 10 1. Wear safety glasses 2.

G012120 Figure 32 Position B G012122 Figure 34 Use this position when bagging. Positioning the Seat The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable. To adjust, move the lever sideways to unlock seat (Figure 35). G012121 Figure 33 Position C G008962 Figure 35 This is the full open position. The suggested use for this position is as follows. • Use in tall, dense grass mowing conditions.
WARNING DANGER The engine and hydraulic drive units can become very hot. Touching a hot engine or hydraulic drive units can cause severe burns. Without a grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. Allow the engine and hydraulic drive units to cool completely before accessing the drive wheel release valves.
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 38). The lower rear section of the tractor 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 WARNING Loading a unit onto a trailer or truck increases the possibility of backward tip-over and could cause serious injury or death. Fast Throttle Setting 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.
Long Grass If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. When Stopping If the machine's forward motion must be stopped 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.
