Cutting Height Adjustment
Depending on cutter set-up, there are three methods to
adjust cutting height. Determine which cutter set-up you
have and follow those instructions.
•
Cutting Height Without Gauge Wheel
•
Cutting Height With Side Gauge Wheel
•
Cutting Height With Rear Gauge Wheel
DANGER
!
To avoid serious injury or death:
A pinching and/or crushing hazard exist while operating
extension arm cylinder and/or deck pivot cylinder that can
result in serious bodily injury or death. Do not operating these
cylinders while someone is near the cutter.
Cutting Height Without Gauge Wheel
1.
Set 3-point control lever to self-cancel detent.
2.
Use 3-point control lever to adjust cutter to the
approximate desired cutting height.
3.
With tractor engine at an idle, engage blades. See
instructions for
4.
Travel forward approximately 20 to 50 feet.
5.
Stop tractor, disengage power take-off, 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 tractor.
6.
Measure height of cut grass/material. This distance
is the cutting height. If this height is acceptable, set 3-
point control lever to stop at this height.
7.
If this height is unacceptable, repeat steps 1 to 6 until
desired cutting height is achieved.
IMPORTANT:
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.
Side Gauge Wheel Adjustment
Figure 4-5
Cutting Height With Side Gauge Wheel
Refer to Figure 4-5:
1.
Park cutter on a flat, level, hard surface with
extension arm cylinder retracted.
2.
Extend deck pivot cylinder until deck is horizontal.
3.
Lower tractor 3-point arms until deck is several
inches higher than desired cutting height.
4.
Place tractor gear selector in park or set park brake,
shut engine off, and remove ignition key.
5.
Place support blocks or jack stands under the deck’s
skid shoes.
6.
Without starting the tractor, lower 3-point arms until
deck skid shoes are resting on the supports.
7.
Remove bolts (#2) and adjust side gauge wheel
frame (#1) up or down to one of the holes “A” that is
closest to the desired cutting height.
8.
Replace 1/2"-13 x 1 3/4" GR5 bolts (#2) and lock
nuts (#4). Tighten lock nuts to the correct torque.
9.
If additional adjustments are required, remove
spindle bolt (#3) and adjust gauge wheel up or down
to one of the other holes “B” that best meets desired
cutting height.
10. Replace 3/4"-10 x 7 1/2" GR5 spindle bolt (#3) and
secure with locknut (#5). Tighten locknut to the
correct torque.
11. Return to the tractor, raise 3-point arms up, travel
forward to clear support blocks.
12. At the worksite, lower cutter down to cutting height
and engage blade. See instructions for
13. Travel forward cutting grass for 20 to 50 feet and stop.
14. Disengage power take-off, place tractor gear selector
in park or set park brake, shut engine off, and remove
ignition key. Wait for all components to stop before
dismounting tractor.
15. Dismount tractor and check cutting height of grass.
16. If needed, repeat
“Cutting Height With Side Gauge
above until cutter is set at the correct height.
