To go backward, slowly pull the motion-control levers rearward (Figure 23). • Use caution when making turns. • Slow the machine down before making sharp turns. Driving Forward Note: The engine shuts off when you move the traction-control with the parking brake engaged.
Using the Side Discharge Adjusting the Height of Cut The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Using the Transport Lock The transport lock has 2 positions, and is used with the deck-lift pedal. There is a LOCK position and an UNLOCK position for the transport position of the mower deck (Figure 24).
Adjusting the Height-of-Cut Pin Adjusting the Anti-Scalp Rollers 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 25. 3.
Adjusting the Flow Baffle Cam Locks Positioning the Flow Baffle The following figures are only recommendations for use. Adjustments vary by grass type, moisture content, and the height of the grass. This procedure is applicable only to machines with the flow-baffle locks. Certain models 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.
Position C Alternating the Mowing Direction This is the full open position. The suggested use for this position is as follows: • Tall, dense grass mowing conditions • Wet conditions • Lowers the engine-power consumption • Allows increased ground speed in heavy conditions Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.
Using the Drive-Wheel-Release Valves After Operation After Operation Safety General Safety WARNING Hands may become entangled in the rotating drive components below the engine deck, which could result in serious injury. • Clean grass and debris from the cutting units, mufflers, and engine compartment to help prevent fires. Clean up oil or fuel spills.
