Cutting Height Adjustment
Refer to Figure 2-5:
1.
At the cutting site, unfold wings and raise center deck
fully up with tractor hydraulic control lever.
2.
Shut tractor down properly without lowering
implement before dismounting. Refer to
Cutting Height Adjustment Using Stroke Control Spacers
Figure 2-5
3.
Remove all stroke control spacers (#2) from center
hydraulic cylinder (#1) by spreading them apart at
the break line. Store spacers in a location they can be
retrieved.
4.
Start tractor and engage blades. See instructions for
5.
Using tractor control lever, adjust cutter to the desired
cutting height and then travel forward for
approximately 20 to 50 feet.
6.
Shut tractor down properly without changing cutting
height.
7.
Measure height of cut grass/material. This distance
is the cutting height. If this height is acceptable,
continue with step 8. If this height is unacceptable,
repeat steps 4-7 until desired cutting height is
achieved.
8.
Select required size and number of stroke control
spacers (#2) that will fit on the center hydraulic
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
NOTE:
Make all cutting height adjustments in the
field using height of cut grass/material as a guide.
Do not measure blade height above ground as the
non-operating blade height will be different than the
operating blade height.

9.
Return to the tractor and raise Rotary Cutter up
again.
10. Without lowering the cutter, shut tractor down
properly before dismounting.
11. With tractor shut off and switch key removed, install
selected stroke control spacers on the center
hydraulic lift cylinder rod.
12. Start tractor and lower cutter against stroke control
spacers.
13. Recheck cutting height in steps 4 to 7. If needed,
adjust size and quantity of stroke control spacers
until desired cutting height is achieved.
14. Keep remaining spacers with tractor for field
adjustments.
NOTE:
Removing spacers lowers cutting height and
adding spacers raises cutting height.
