4. Loosen u-bolts (#4) and move hitch frame (#3):
•
If plow needs to be moved to the right, move hitch
frame (#3) to the left the measured distance
recorded in step 1.
•
If plow needs to be move to the left, move hitch
frame (#3) to the right the measured distance
recorded in step 1.
5. Re-tighten nuts on the 5/8"-11 u-bolts (#4) to the
correct torque.
6. Hook-up plow to tractor. Refer to
7.
Recheck alignment of the wing tip to furrow.
Align Plow to Trail Straight
Refer to Figure 2-1 on page 12:
The plow should pull straight. If it is not, make sure the
lower 3-point arms have been stabilized. If stabilizers
have too much slack, the lower 3-point arms may still
want to sway to one side. Review your tractor Operator’s
Manual to see if there is a way to hold the lower arms
from swaying, especially on the side that needs to hold
against the plow’s side forces.
If the lower 3-point arms cannot be properly stabilized,
reposition the right-hand lower 3-point hitch pin (#15) in
the lower hitch frame as follows:
1.
Raise plow out of the ground and park tractor with
plow on level, hard ground.
2. Unhook plow from tractor. See
3. Remove hex nut (#26), lock washer (#25), and hitch
pin (#15).
4. Hitch pin (#15) is shipped from the factory mounted in
hole “B”. Move hitch pin forward or rearward one hole:
•
If back of plow is angling to the left, move hitch
pin (#15) back to hole “A”.
•
If back of plow is angling to the right, move hitch
pin (#15) forward to hole “C”.
5. Secure hitch pin (#15) with lock washer (#25) and
hex nut (#26). Do not tighten hex nut at this time.
6. Insert a drive punch in linchpin hole and rotate hitch
pin with drive punch until linchpin hole is vertical.
7.
Refer to Hitch Pin Detail:
Verify center of linchpin
hole is 1 13/16" from face of jam nut (#24).
8. Tighten 7/8"-14 hex nut (#25) to the correct torque for
a GR5 bolt.
Coulter Alignment (Option)
Refer to Figure 2-1 on page 12:
CAUTION
!
To avoid minor or moderate injury:
Coulter blades are sharp and can cause deep cuts. To prevent
serious bodily injury, wear gloves when working with coulters
and keep bodily extremities out from under the coulters.
Coulters cut through surface trash and plant roots to help
form a clean, smooth furrow wall. They also help the plow
cover trash and reduce pulling forces.
1.
Lower plow until it is resting on the ground.
2. Shut tractor down properly. Refer to
3.
Align Coulter Left to Right:
The coulter shank
should be rotated until the blade is in line with the
share point. This arrangement requires the least
horsepower to pull the plow and helps keep excess
trash from building-up on the plow shank (#19).
a. Loosen hex nuts securing bolts (#7) and rotate
offset shank (#8) until coulter (#12) is in line with
the share point.
b. Tighten 3/4"-10 hex nuts for GR5 bolts (#7) to the
proper torque.
c. Loosen set screw (#10) and rotate stop (#9) until
colter has equal swinging arc on both sides of
normal operating position (straight back).
d. Tighten set screw (#10) to the correct torque.
e. Recheck coulter swing to make sure it does not
contact tractor, tractor tires, or plow components.
If needed readjust coulter stop (#9).
f.
MP20 Model only:
Repeat steps a-e above for
the rear coulter (rear coulter not shown).
4.
Align Coulter Vertically:
The coulter (#12) should
be set 3" to 4" deep into the ground to cut through
trash and plant roots. If it is set too deep, it will push
trash. Never set the coulter so deep as to cause the
hub (#13) to run in the dirt.
a. Loosen hex nuts securing clamp bolts (#7) and
raise or lower front coulter (#12) until the coulter
blade is set 3" to 4" deep into the ground. (ie. If
you are plowing 6" deep, the bottom of the coulter
should be set 2" to 3" above ground with plow
shares resting on the ground surface.
b. Make sure coulter(#12) is in line with the share
point and tighten 3/4"-10 hex nuts to the proper
torque for GR5 bolts (#7).
c.
MP20 Model only:
Repeat steps a-b above for
the rear coulter (rear coulter not shown).
