3.
With gloves on, carefully rotate each blade tip to the
position shown in Figure 3-2.
4.
Measure distance from cutting tip of blade to ground
surface. This distance is the cutting height.
5.
If desired cutting height cannot be obtained by
adjusting the lower 3-Point arms, then readjust
tailwheel height. See
6.
Repeat steps 1 to 5 until desired cutting height is
achieved.
7.
Set tractor’s 3-Point hydraulic control stop at this
height.
Tractor Center 3-Point Adjustment
Refer to Figure 3-3:
1.
Lower cutter deck to the nominal cutting height.

2.
Typically the tractor center 3-point link is adjusted so
that the upper 3-point clevis pin is straight above the
lower 3-point hitch pins. This arrangement allows for
optimum ground contour following performance.
3.
Lock tractor center link in this position once correct
length is achieved. Adjustment on center 3-point link
can be made depending on customer’s preference.
Tailwheel Height Adjustment
Refer to Figure 3-4:
If deck slope is slightly lower at the front than at the back
and cutting height is not at the desired height, then the
tailwheel must be adjusted up or down as follows:
1.
Use tractor’s 3-Point hydraulic control to lift cutter
until the tailwheel clears the ground.
2.
Remove 3/8" carriage bolt (#1) and 3/8" flange
nut (#2).
3.
Adjust tailwheel as follows:
•
To lower cutting height, adjust tailwheel up.
•
To increase cutting height, adjust tailwheel down.
4.
With tailwheel adjusted to the correct height, replace
3/8" x 1" long carriage bolt (#1) and 3/8" flange
nut (#2). Tighten flange nut to the correct torque.
5.
Readjust tractor’s lower 3-Point arm height as
needed. See section titled
NOTE:
Customer may adjust tractor center 3-point
link to his or her preference. Lengthening center
3-point link allows more movement going over raised
surfaces. Shortening the link allows more movement
crossing ditches and allows the cutter to be carried
higher while traveling. Never lengthen center link to
where the cutter is carried too low.
