Adjusting Mold Board Angle
The mold board can be adjusted to three different angles
to provide for varying degrees of aggressiveness.
See Figure 3-5. Set the mold board at rearmost hole (A)
for aggressive grading. Use forward positions (B) for a
smoother surface.
Figure 3-5. Adjusting Mold Board Angle
To adjust mold board angle:
1. See Figure 3-5. Remove top bolt and locknut (A)
on both mold board ends using two 9/16"
wrenches.
2. Loosen bottom bolt and locknut (C) using two 9/16"
wrenches so mold board can be rotated.
3. Align mold board hole (A) with hole at desired
angle setting (B).
4. Reinstall top bolts and locknuts and tighten all
hardware.
Converting Mold Board to Smooth or Grooved
Edge
•
The mold board can be mounted with straight edge
down for basic grading or for creating smoother
surfaces in finer materials.
• The mold board can be mounted with grooved
edge down for aggressive grading or for creating
grooved surfaces in finer material.
Proceed as follows to convert molding board from one
edge to the other.
1. See Figure 3-6. Remove bolts and locknuts (A)
securing both mold board ends to power grader
frame using two 9/16" wrenches.

2. See Figure 3-7. Remove mold board and position
with desired edge down and welded angle (B) fac-
ing the rear of the machine.

Operating Tips
NOTE: Frequently verify the tightness of bolts fastening
tooth bar and mold bar to the frame.
• Avoid large rocks, embedded ledge, cattle guards
or similar obstructions. After each pass remove
rocks pulled to the surface.
• Verify tooth bar is in the raised position before turn-
ing around or leaving work area.
• Avoid pot holes filled with water.
• Work the edges of pot holes more than 4 ft
(1.22 m) wide to loosen sides before filling them.
• Expect to make several passes when repairing a
roadway.
• Once a road surface has been adequately scari-
fied, raise the teeth plate to allow rear scraper
blade to create a smooth surface.
