Adjust Cutter Height
Refer to Figure 2-5:
1. At the cutting site, unfold wings and raise center deck
fully up with the lift cylinder.
2. Without relieving hydraulics, shut tractor down before
dismounting according to
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. Open all flip spacers (#2) on lift cylinder (#1).
4. Start tractor and engage blades. See
on page 42 for detailed instructions.
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.
IMPORTANT:
Whether engaging or disengaging
stroke control flip spacers, take time to ensure they
are in the fully open or fully closed position. Flip
spacers not in the fully closed or fully open position
can cause damage to the lift cylinder and/or flip
5. Using tractor control lever, adjust cutter to the desired
cutting height and then travel forward for
approximately 20 to 50 feet (6 to 15 meters).
6. Without relieving hydraulics, shut tractor down before
7.
Measure height of cut grass/material. This
measurement is the cutting height. If this height is
acceptable, continue with step 8. If this height is
unacceptable, repeat steps 1-7 until desired cutting
height is achieved.
8. Count the required number of flip spacers (#2) to
meet desired cutting height.
9. Return to tractor and raise Rotary Cutter up again.
10. Without lowering the cutter, shut tractor down before
11. With tractor shut off and ignition key removed, close
the amount of flip spacers (#2) determined in step 8.
12. Restart tractor and lower cutter against flip
spacers (#2).
13. Recheck cutting height using steps 4-7. If needed,
adjust number of flip spacers (#2) until desired
cutting height is achieved.
14. Keep remaining flip spacers (#2) in the fully open
position.
NOTE:
Opening flip spacers lowers cutting height
and closing flip spacers raises cutting height.
