Moldboard and Implement Operation
Digging
NOTE:
Always keep cutting edges in good condition. Dull and worn edges increase power
demands on the motor grader.
When starting a ditch, position moldboard so end (right or left) is directly behind and 76 mm (3 in)
below the front wheel. Position the other end of the moldboard as high as possible.
The first cut should be slow enough to maintain control of the grader and cut a straight ditch line.
Only dig deep enough to create a shallow ditch and line to follow for subsequent passes. Lean the
front wheels in the direction of the discharge to counteract the load.
For the second pass, position the wheels inside the ditch and, with a slightly higher speed than the
first pass, maintain a 3:1 ratio between width and depth.
Discharge the material under the rear module between
the rear wheels. If the material accumulates under the
machine, it should be cast aside with a "cleaning" pass
before taking another cut. For the cleaning pass, the
moldboard should be tilted forward slightly to handle
more material.
A deeper ditch requires more cleaning passes and side
casting of material.
If a "V" ditch is required, each side of the ditch must be
cut alternately to permit the front and rear wheels to
travel in the center of the ditch.
Filling Trenches or Ditches
When required to cast material over the edge of a ditch,
fully shift the moldboard toward the ditch so the grader
wheels are away from the edge
(1)
. The weight of the
motor grader could cause the edge to collapse. Offset the
rear module
(2)
away from the ditch using the
articulation capability to move the weight of the machine
farther away from an edge.
All material should be discharged from the end of the
moldboard and into the ditch.
Electricity or gas explosion can kill. Laser light in cut cable can result in eye
damage.
Locate utilities before digging. Call 811 (U.S. only) or 1-888-258-0808 (U.S. or
Canada) or local utility companies or national regulating authority.
