Blade Offsetting
Refer to Figure 3-4:
The blade may be offset 12" right or left by unbolting
moldboard (#1) from moldboard mount (#2) and rebolting
it using alternate holes “A” or “B” depending on which
direction the blade is being offset.
1.
Remove two carriage bolts (#3) and three 1 3/4" long
plow bolts (#4) from center of moldboard (#1) and
moldboard mount (#2).
2. On side to be shortened, remove 1 1/2" long plow
bolt (#4) 12" from removed 1 3/4" long plow bolts.
3. Shift moldboard (#1) 12" to the right or left & reattach
it to moldboard mount (#2) with 1/2"-13 x 1 1/2" GR5
carriage bolts (#3), hex flange locknuts (#5),
5/8"-11 x 1 3/4" plow bolts (#4), and hex flange
locknuts (#6). Tighten locknuts to the correct torque.
4. Install 5/8"-13 x 1 1/2" plow bolt (#4) in the remaining
hole and secure with hex flange locknut (#6). Tighten
locknut to the correct torque.
