Refer to Figure 3-10:
3. Adjust cutting height with either the ratchet jack (#1)
or hydraulic cylinder (#2) as follows:
Ratchet Jack Instructions
a. Raise or lower cutter with the ratchet jack (#1) by
setting the mechanism in the jack handle.
b. Pump jack handle to raise or lower cutter until set
to the desired traveling height or cutting height.
c. If ratchet jack is working opposite of what is
needed, reset mechanism in jack handle and
return to pumping the jack handle.
Hydraulic Cylinder Instructions
a. Stroke control spacers (#3) are included with
hydraulic cylinder (#2). They consist of cast
aluminum halves with spring clips to hold the two
halves together.
b. With tractor hydraulics, extend hydraulic cylinder
to free up space on the cylinder rod.
c. Remove all stroke control spacers (#3) from
cylinder rod by spreading spacers apart at the
break line.
d. Using tractor hydraulic cylinder control lever,
lower Rotary Cutter to the desired cutting height.
Measure this distance to verify cutting height is
correct.
e. 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
• One 1 3/4" spacer
f. Return to the tractor and raise Rotary Cutter up.
Install selected size and number of stroke control
spacers on the cylinder rod.
g. Retract hydraulic cylinder until stroke control
spacers are supporting the cutter weight.
h. Recheck deck profile. If needed, adjust size and
quantity of stroke control spacers until correct
deck profile is achieved.
i. Unused stroke control spacers may be stored on
hydraulic hose (#4) near the hydraulic cylinder.
