gloves. Cutter blades have sharp edges and burrs that can
1.
Follow
when dismounting from tractor.
2. With gloves on, carefully rotate blade tips on one side
of the cutter to the position shown.
3. Measure distance from cutting tip of front blade to
ground surface. This distance is the cutting height.
4. Restart tractor to use tractor’s 3-point hydraulic
control lever to raise or lower 3-point lift arms until the
front blade tip is at the desired cutting height.
5. The top center 3-point link should be loose when
deck rear is supported by the tailwheel. If not, shut
tractor down and lengthen center 3-point link until
loose. Final adjustment will be made later.
6. With tractor shut down, measure distance from
cutting tip of rear blade to ground. This distance
should be slightly higher than the front blade but not
more than 1" higher.
IMPORTANT:
The front blade tip should be lower than
7.
If rear blade is lower than the front blade or is more
than 1" higher than the front blade, then the tailwheel
heights must be adjusted. If needed, see
8. Repeat steps 2-7 until tailwheel and 3-point arms are
adjusted to the desired cutting height.
9. Set tractor’s 3-point hydraulic control stop once the
tailwheel and 3-point arms are adjusted properly.
Adjust Tailwheel Height
With Rotary Cutter lowered to approximate cutting height,
measure distance from end of front blade cutting tip to
ground and from end of rear blade cutting tip to ground.
The tailwheel must be adjusted up or down if the rear
blade tip is one of the following:
•
Same distance off the ground as the front blade.
•
Lower than the front blade.
•
More than 1" higher off the ground than the front blade.
Adjust tailwheel to lower the cutter or raise the cutter as
follows:
Lower Deck Cutting Height
Refer to Figure 3-3 on page 27:
1.
Raise cutter up until tailwheels are a little higher than
the distance the tailwheels are to be lowered.
2. Follow
before dismounting tractor.
NOTE:
The unit cuts most efficiently if front of cutter
is slightly lower than back of cutter.
