WARNING
Always disengage PTO, engage parking brake, shut off
tractor, remove ignition key, and wait for all moving parts to
come to a complete stop before dismounting from tractor.
!
CAUTION
Avoid direct contact with cutter blades by wearing a pair of
gloves. Cutter blades have sharp edges and burrs that can
cause injuries.
Hydraulic Cylinder Instructions
Refer to Figure 2-7:
At the front of the cutter, measure distance from cutting
tip of blade to ground. This distance is the cutting height.
Use tractor hydraulic cylinder control lever to change
cutting height.
1.
With tractor hydraulics, raise cutter fully up.
2.
Remove all stroke control spacers (#6) from cylinder
rod (#3) by spreading spacers apart at the break line.
3.
Using tractor hydraulic cylinder control lever, lower
Rotary Cutter to the desired cutting height. Measure
this distance to verify cutting height is correct.
4.
Select required size and number of stroke control
spacers (#6) 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
•
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.
Ratchet Jack Instructions
Refer to Figure 2-8:
At the front of the cutter, measure distance from tip of
front cutting blade to ground. This distance is the cutting
height. Use ratchet jack to change cutting height.
1.
Raise cutter blades by setting ratchet jack lock and
pumping the ratchet jack lever back and forth to
lengthen ratchet jack until desired cutting height is
achieved.
2.
Lower cutter blades by reposition ratchet lock and
pumping the ratchet jack lever back and forth to
shorten the ratchet jack until desired cutting height is
achieved.
NOTE: Removing spacers lowers the cutting height
and adding spacers raises the cutting height.
