3.03 - Cutting Height Adjustment
WARNING: Keep hands and feet away from moving blades.
Be sure tractor engine is off, parking brake is locked, and key is removed before
making any adjustments.
Never rely on the tractor lift system. Install blocks or stands under the shredder
deck to prevent it from falling.
The cutting height is the distance from the blades to the ground. It is changed by
adjusting the position of the rear roller
(see fig. 4) . All shredders are equipped with a
roller scraper that helps keep the roller clean and the cutting height consistent.
The machine has 9 different cutting height positions. The cutting height is
adjustable from ¾” to 5” in approximately ½” increments.
Cutting lower than 2”
under most circumstances should be avoided. Make sure blades do not touch the
ground. Blades that contact the ground will wear out faster and may cause excessive
vibration to the rotor.
To change the cutting height do the following (see fig. 4) :
1. Unbolt and remove the 4 bolts, 2 on each side, (see #1, fig. 4) that secure the roller
height position.
2. Move the roller into its desired position and insert the bolts into two of the available
holes. Tighten all 4 bolts. Assembling the roller to the lower holes will increase
cutting height while assembling the roller to the higher holes will reduce cutting
height.
