5.2.5 BACKFILLING
When backfilling, ensure there are no cavities remaining, tamp your backfill at regular intervals to avoid
settling issues.
Backfill using your
front loader:
• Position the tractor so the spoil pile is be-
tween the tractor and the dig
• Push the spoil pile into the dig.
Backfill by
dragging:
• Position the tractor so the spoil pile is on
the far side of the dig
• Reach over the dig with the boom and drag
the spoil pile into the dig.
Backfill with the bucket:
• Position the tractor so the spoil pile is the same distance as the dig
• lower the extended bucket into the spoil pile.
•
Curl the bucket to fill with dirt, and lift it clear of the spoil pile.
• Swing the bucket to the excavation and extend the bucket to drop the dirt into the dig .
• Return the bucket to the spoil pile and con-
tinue the cycle until the job is completed.
• IMPORTANT
: Do not backfill by using
the swing circuit and dragging the bucket
sideways. Doing so could cause damage
to the dipper, boom, and swing cylinders or
mainframe.
5.2.6 HARD GROUND
When digging in hard ground, it may be necessary to decrease the bucket angle of entry
to the point where the back of the bucket almost contacts the ground. It may also be necessary
to apply downward pressure with the boom.
5.2.7 LIFTING
The backhoe can be used to lift and place lines, pipes or other loads into trenches or excavations.
The boom lift capacity with the boom fully extended 1 meter (3’) from ground are:
GE605
113 kg (250 lb)
GX620
175 kg (385 lb)
GX720
420 kg (925 lb)
GX920
340 kg (750 lb)
GX920XT
322 kg (710 lb) / 263 kg (580 lb) extended
Do not exceed the lifting capacity of the backhoe. Inspect the item to be lifted and do not overload.
• Always position the tractor at right angles to the trench or excavation when moving loads.
• Do not swing loads over people when placing loads in trenches or excavations.
•
Use a
tag line if transporting the load to prevent the load from swinging.
• If transporting, plan your path and ensure it is clear, free of bystanders and debris.
NOTE:
Avoid constant jarring or hammering contact between
the spoil pile and the loaded bucket as this may cause prema-
ture wear to the backhoe pins and bushings.
