Cutting Height Adjustment
Refer to Figure 2-5:
1. At the cutting site, unfold wings and raise center deck
fully up with lift cylinder.
2. Shut tractor down properly before dismounting. Refer
to “Tractor Shutdown Procedure” on page 13.
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 “Engage
Blades” on page 31 for detailed instructions.
5. Using tractor control lever, adjust cutter to the desired
cutting height and then travel forward for
approximately 20 to 50 feet.
6. Stop tractor, disengage PTO, place tractor gear
selector in park or set park brake, shut off tractor,
remove key, and wait for blades to come to a
complete stop before dismounting from tractor.
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 thru 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 tractor and raise Rotary Cutter up again.
10. Without lowering the cutter, shut tractor down
properly before dismounting. Refer to “Tractor
Shutdown Procedure” on page 13.
11. Install selected stroke control spacers on the center
cylinder rod.
12. Return to the tractor and lower cutter against stroke
control spacers.
13. Recheck cutting height using steps 4 thru 7 above. 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.

Refer to Figure 2-6:
The LP Performance hitch is designed to receive
1" diameter hitch pins. To convert the hitch to receive
