DITCHING WORK

Ditching work can be performed efficiently by attaching a buck-
et which matches the ditching operation, and then setting the
wheels parallel to the line of the ditch to be excavated.
To excavate a wide ditch, first dig both sides and then finally re-
move the center portion.

SIDE DITCHING WORK

The operator can perform ditching work in a narrow space by
combining swing and boom swing operations.

LOADING WORK

In places where the swing angle is small, work efficiency can
be enhanced by locating the dump truck in a place easily visi-
ble to the operator.
Loading is easier and capacity becomes greater if you stop the
machine at the rear of the dump truck than if loading is done
from the side.

LEVELING WORK

Use the blade for back filling and leveling work after digging the
ground.
