Adjust Cutter Height
Refer to Figure 2-4:

2. Without relieving hydraulics, shut tractor down
properly before dismounting. Refer to “Tractor
Shutdown Procedure” on page 13.

WARNING
!
To avoid serious injury or death: Stay clear from underneath
the cutter and directly behind transport tires. The cutter could
fall suddenly causing the decks to lower and tires to roll back.
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 33 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. Without relieving hydraulics, shut tractor down
properly before dismounting. Refer to “Tractor
Shutdown Procedure” on page 13.
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.
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.

10. Without lowering the cutter, shut tractor down
properly before dismounting. Refer to “Tractor
Shutdown Procedure” on page 13.
11. With tractor shut off and switch key removed, install
selected stroke control spacers on the center
hydraulic lift cylinder rod.
12. Restart tractor and lower cutter against stroke control
spacers.
13. Recheck cutting height using steps 4-7 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.
LP Performance Hitch Hole Size
Refer to Figure 2-5:
The LP Performance hitch pin hole is designed to receive
a 1" diameter hitch pin. To convert the hitch to receive
1 1/4" diameter hitch pin, knock out upper and lower
bushings (#1) in clevis (#2).
