Tailwheel Height (3-Point)
WARNING
!
To avoid serious injury or death:
Avoid direct contact with cutter blades by wearing a pair of
gloves. Cutter blades have sharp edges and burrs that can
cause injuries.
If front blade tip is set at the desired cutting height and
back blade tip is at the same height or lower or is higher
than the front blade tip by more than 1", then the
tailwheels must be adjusted up or down as follows:
Ratchet Jack
Refer to Figure 3-3:
Change rear blade height with ratchet jack as follows:
1. Setting ratchet jack lock and pumping ratchet jack
lever back and forth until rear blade height is slightly
higher than front blade tip but by not more than 1".
Hydraulic Cylinder
Refer to Figure 3-4:
Change rear blade height hydraulically as follows:
1. With tractor hydraulics, raise cutter fully up.
2. Remove all stroke control spacers (#3) from cylinder
rod (#1) by spreading spacers apart at the break line.
3. Using tractor control lever for the hydraulic cylinder,
lower Rotary Cutter until rear blade height is slightly
higher than front blade tip but not by more than 1".
4. Select required size and number of stroke control
spacers (#3) that will fill the exposed cylinder rod.
The following spacers are available:
Two 1" spacers, one 1 1/4" spacer, one 1 1/2" spacer,
and one 1 3/4" spacer
5. Return to the tractor and raise Rotary Cutter up.
Install selected size and number of stroke control
spacers on the cylinder rod.
6. Lower Rotary Cutter against stroke control spacers
and recheck cutting height. If needed, adjust size and
quantity of stroke control spacers until desired
cutting height is achieved.
Center 3-Point Link (3-Point)
Refer to Figure 3-5:
1. Lower cutter deck to preset cutting height.
2. For optimum ground contour following performance,
adjust length of center 3-point link until center hitch
pin is vertically above lower 3-point hitch pins.
3. Lock center 3-point link in this position.
NOTE: Removing spacers (#3) lowers the cutting
height and adding spacers raises the cutting height.
NOTE: The lower bolted-on-bushing in the center
hitch is used with a Quick Hitch attachment.
