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 inch) cutting height position) (Figure 25). 3. To adjust, rotate the pin 90 degrees and remove the pin from the height-of-cut bracket (Figure 25). 4.
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 26 1.
Positioning the Flow Baffle • Use in tall, dense grass mowing conditions. The following figures are only recommendations for use. Adjustments will vary by grass type, moisture content, and height of grass. • Use in wet conditions. • Lowers the engine power consumption. • Allows increased ground speed in heavy conditions. Note: If the engine power draws down and the mower ground speed is the same, open up the baffle. • This position is similar to the benefits of the Toro SFS mower.
Using the Drive Wheel Release Valves 4. Rotate the release valve levers horizontally to run the machine (Figure 34). Using the Side Discharge WARNING The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf.
