FILLING 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 the bucket 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 crowd 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 build-up of

material directly in front of the backhoe, crowd 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 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 dipstick 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 pin and

bushings.

TRENCHING BETWEEN A BUILDING & OPEN

EXCAVATORS

Start the trench at the building. Trench out halfway to the

excavation. Then, start trenching from the excavation to the

first trench. Dig toward the first trench until there is just

enough room to move the unit out from between the two

trenches.
