Adjusting the Power Grader for Grading and Scarifying
1.
Rotate the Crank Knob counterclockwise until the Slider is at the bottom of
the scale to lower the machine and take all of the weight off the Wheels
(
Figure 33 ).
Note:
The Wheels must be set fully up off the ground when Grading or Scarifying.
2.
Remove the Snap Safety Pins ( Figure 34 ) and adjust the Pin Hitch
Assembly as described below:

Position the Tow Bar to the highest position for most aggressive grading
(
Figure 34 ).

Position the Tow Bar to the lowest position for most aggressive scarifying
(
Figure 35 ). See “Adjusting the Mold Board” for other Mold Board
settings.

Use the remaining Tow Bar Hitch mounting positions for varying degrees
of Grading and Scarifying.
Using the Mold Board
ADJUSTING THE ANGLE:
The Mold Board angle can be set at three different angles to determine how
aggressively it moves and molds the material.
Tools Needed:

Two 9/16" Wrenches
1.
Remove the top Bolt and Locknut on both ends of the Mold Board using
two 9/16" Wrenches (
Figure 36 ).
2.
Loosen the Bottom Bolt and Locknut using two 9/16" Wrenches so the
Mold Board can be rotated.
3.
Rotate the Mold Board to align with the holes at the desired setting.
4.
Reinstall the top Bolts and locknuts and tighten all hardware.
CONVERTING TO SMOOTH OR GROOVED EDGE:
The Mold Board can be mounted with the straight edge down for basic grading
or for creating smoother surfaces in finer materials. It can also be mounted
with the grooved edge down for more aggressive grading or for creating
grooved surfaces in finer materials.
Tools Needed:

Two 9/16" Wrenches
1.
Fully raise the Wheels ( Figure 33 ) and remove the Snap Safety Pin from the
Cable Spring Bracket to rotate the Axle Assembly out of the way ( Figure 37 ).
