Digging
Proper Bucket Position
Move the flat side of the bucket so it is parallel to the
ground (Figure 3-37).
Figure 3-37 Proper Bucket Position
Proper Digging Technique
1. Lower the bucket into the ground (4, Figure 3-38).
2. After the bucket penetrates the ground, adjust it so
its flat side is parallel to the ground (5, Figure 3-
38).
3. Pull the bucket towards the excavator by:
a. Moving the dipper arm toward the excavator,
and
b. Lowering the boom.
4. After the bucket is sufficiently filled:
a. Continue moving the dipper arm toward the
excavator,
b. Extend the dipper arm cylinder so the bucket is
tilted upward (6, Figure 3-38).
c. Raise the boom.

Trench Excavating
Trench excavating is most efficient when the machine
tracks are parallel to the line of the trench (Figure 3-
39). For larger trenches, excavate each side first and
then the center.
Figure 3-39 Efficient Trench Excavating
IMPORTANT
Positions 2 and 3 in Figure 3-37 show
improper positions for using the bucket.
Position 2 forces the bucket downward into
the ground, slowing down work and
subjecting the engine and hydraulic pump
to overloading.
Position 3 forces the bucket upward toward
the ground surface, reducing productivity
because of smaller loads being dug.
