Filling the Bucket
Control the bucket attitude
throughout the digging cycle to
keep teeth at the proper angle
for best penetration. This will
minimize dragging and scraping
through the ground.
When digging in hard-packed soil,
bucket penetration can be increased
by applying down pressure with the
boom while crowding in and curling
the bucket. If the crowed action
“stalls” it may be necessary to apply
lift occasionally during the digging
cycle to correct the bucket depth.
To obtain a cleaner trench and
avoid the buildup of material
directly in front of the backhoe,
crowed out and completely curl
the bucket while starting to lift it
from the excavation. In this way,
excess material will fall back into
the excavation.
Dumping the Bucket
• To dump the bucket at the end of the digging cycle, lift the
bucket clear of the trench while crowding it out and swinging
it to the spoil pile.
• As the pile is approached, dump the bucket. When the bucket
is empty, the dipper stick and bucket are in position to resume
digging upon return to the trench.
IMPORTANT: Avoid constant jarring or hammering type contact
between the spoil pile and the loaded bucket, as this may cause
premature wear to the backhoe pins and bushings.
Trenching Between A Building and Open Excavations
Start the trench at the building.
Trench out halfway to the excavation.
Then start trenching from the
excavation to the rst trench. Dig
toward the rst trench until there is
just enough room to move the unit
out between the two trenches.
GENERAL OPERATIONGENERAL OPERATION
Position the unit so the backhoe
swing post is over the centerline of
the trench connection. Dig with the
backhoe at extreme swing positions,
and in as close to the stabilizers
as possible. Pile the spoil on the
opposite side of the trenches.
Position the unit forward with the
lift and crowed levers so the two
trenches can be connected. Pile
the spoil on the opposite side of
the trench.
