Moldboards
Refer to Figure 4-2 on page 18:
Moldboards (#7) should be inspected annually for wear.
Replace moldboards and mounting hardware as needed.
1.
Remove hex nuts (#10), lock washers (#9), plow
bolts (#8) and
moldboard
(#7).
2. Using holes “C” in frog (#13), reattach new
moldboard (#7) with plow bolts (#8), lock
washers (#9), and hex nuts (#10).
3. Tighten hex nuts (#10) to the correct torque.
Coulter Blades
Refer to Figure 4-2 on page 18:
Inspect coulter blades (#11) for horizontal alignment and
cutting depth. If necessary, readjust coulters. Refer to
Check coulter blades (#11) to make sure they run
vertical. If a blade does not run vertical, the bent parts
must be replaced or the coulter will not operate properly.
Keep coulter bearings greased. Refer to
Replace coulter blades (#11) and mounting
hardware (#12, #4, & #5) as needed:
1.
Remove hex nuts (#5), lock washers (#4), carriage
bolts (#12) and coulter blade (#11).
2. Reattach new coulter blade (#11) with carriage
bolts (#12), lock washers (#4), and hex nuts (#5).
3. Tighten hex nuts (#5) to the correct torque.
Landslides
The landslides (#1 & #2) and heel (#3) should be
inspected for wear frequently. Replace landslides and
mounting hardware as needed.
1.
Remove nuts (#7A & #9), lock washers (#8A & #10),
hex head bolts (#4 & #5), and landslide (#1 or #2).
2. Position new landslide (#1or #2) with holes “A” 2 1/2"
up from bottom and hole “B” on landslide (#2) below
holes “A” as shown.
3. Attach new landslide (#1or #2) to frog (#11) with 3/4"
hex head bolt (#4), lock washer (#10), and hex
nut (#9).
4. Insert 1/2" shear bolt (#5) in landslide (#1 or #2),
frog (#11), and secure with lock washer (#8A) and
hex nut (#7A).
5. Tighten hex nuts (#7A & #9) to the correct torque.
6. Attach heel (#3) to landslide (#2) with
1/2" hex bolt (#6), lock washer (#8B) and hex
nut (#7B).
7.
Rotate bottom of heel angle brace (#3) to be parallel
with bottom of landslide (#2) and tighten nut (#7B) to
the correct torque.
