Section 2: Adjustments
NOTE: Customer may adjust center 3-point link to
his or her preference. Lengthening center 3-point link
allows more movement while going over raised
surfaces. Shortening the link allows more movement
while crossing over ditches. Also, shortening center
link allows the cutter to be carried higher while
traveling. Never lengthen center link to where the
cutter is carried too low.
3. Lock center link in this position once correct length is
achieved. Adjustment on center 3-point link can be
made depending on customer's preference.
Single Tail Wheel Height Adjustment
Refer to Figure 2-3:
The single tailwheel must be adjusted if cutting height is
too high or too low.
1.
Use tractor's 3-point hydraulic control to lift the
tailwheel off the ground.
2. Remove 1/2" -13 x 1 1/2" GR5 carriage head bolt (#5)
and 1/2" hex flange locknut (#6).
3. Adjust tailwheel (#2) up or down to desired cutting
height by repositioning adjusting plate (#1) and
replace attaching hardware.
Dual Tail Wheel Height Adjustment
Refer to Figure 2-4:
The dual tailwheels must be adjusted if cutting height is
too high or too low.
1.
Use tractor's 3-point hydraulic control to lift the
tailwheels off the ground.
2. Remove 1/2" -13 x 3 1/2" GR5 bolts (#2).
3. Adjust tailwheel (#1) up or down to desired cutting
height and reinsert 1/2" -13 x 3 1/2" GR5 bolts (#2).
4. Secure 1/2" bolts with 1/2" flange lock nuts (#3).
Tighten lock nuts to correct torque.
For best cutting efficiency, adjust the lower
3-point arm height such that the front
cutter blade is approximately 1" lower than
the rear cutter blade.
