RT ST A N RU Using the Safety-interlock System P ST O G008947 Figure 19 CAUTION If safety-interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury.
Using the Motion-control Levers Testing the Safety-interlock System Service Interval: Before each use or daily Test the safety-interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately. 1. Sitting on the seat, engage the parking brake and move the blade-control switch (PTO) to the On position. Try starting the engine; the engine should not crank. 2.
Stopping the Machine To stop the machine, move the traction-control levers to neutral, and then move them to the locked position, disengage the power take off (blade-control switch (PTO), and turn the ignition key to the Off position. Set the parking brake when you leave the machine; refer to Setting the Parking Brake (page 19). 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 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. 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 140 mm (5-1/2 inches) cutting height position) as shown in Figure 26. 3.
Adjusting the Flow Baffle Cam Locks 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. The mower-discharge flow can be adjusted for different types of mowing conditions. Position the cam locks and baffle to give the best quality of cut. 1. Disengage the blade-control switch (PTO), move the motion-control levers to the neutral-locked position, and set the parking brake. Figure 27 1.
Position A This is the full rear position. The suggested use for this position is a follows: • • • • Short, light grass mowing conditions Dry conditions Smaller grass clippings Propels grass clippings farther away from the mower Figure 33 Figure 31 Positioning the Seat Position B The seat moves forward and backward. Position the seat where you have the best control of the machine and are most comfortable. Use this position when bagging. Always align it with the blower opening.
Changing the Seat Suspension neutral-locked position, apply the parking brake, and remove the key. The seat adjusts to provide a smooth and comfortable ride. Position the seat where you are most comfortable. 2. Rotate the release-valve levers vertically to push the machine (Figure 37). To adjust, turn the knob in front either direction to provide the best comfort (Figure 36). Note: This allows hydraulic oil to bypass the pump enabling the wheels to turn. 3.
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 the 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 39). 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.
Cutting Long Grass Operating Tips 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. Cutting a Lawn for the First Time Cut grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground.
