Road Building - "V" Ditch Method
0006
N OT E
The steps in this procedure are for one side of the road. Repeat these steps for the
opposite side.
1. Position the grader outside the working area of the project to configure the grader for "V" ditching.
2. Place the grader into ditching position as follows;
a. Raise the moldboard 4-6 in. (100-150 mm) off the surface to allow unrestricted movement.
b. Pitch the blade halfway.
c.
Center the blade on the circle by side shifting if needed.
d. Center shift until the heel cylinder is straight up and down.
e. Rotate the moldboard so the toe is just behind the outside edge of the right front tire.
f.
Raise the heel cylinder all the way up.
g. Lean the front wheels toward the heel.
3. Perform a marking cut followed by a ditching (heavy) cut.
