When digging with the back hoe, the loader arms
should be partially raised with the bucket pointed
outwards, away from the operator.
5.4.1 Digging With Boom
1.
Use the loader and bucket cylinder to set the
back hoe bucket at about a 30 degree angle into
the ground. Set the boom angle so that the teeth
are digging and the heel of the bucket is off the
ground.
2. Tilt the bucket cylinder to pull the back hoe through
the soil until it is full.
3. Curl the bucket up and raise the loader.
4. Rotate the skid steer to dump the load.

5.4.2 Digging With Bucket
1. Use the loader face plate to set the bucket angle
for digging at about 30 degrees to the ground.
2. Use the loader face plate / boom to force the
bucket into the ground and at the same time, curl
the bucket back to fill it.
3. Raise the boom and rotate the skid steer to dump
the bucket.
4. Continue to dig 3–6 in (75–150 mm) deeper each
pass.
WARNING!
Avoid risk of falling into the hole or collapsing
the sides of the hole. Back away from the hole
before rotating machine.

5.4.3 Trenching
1.
Mark out the excavation.
2. Use the boom or bucket method to dig.
3. Make the first cut shallow and accurate. This first
cut keeps the next cuts accurate and the trench
straight.
5.4.4 Filling Holes
1. Use the bucket to reach beyond the trench and
travel in reverse to PULL material into the trench or
hole.
2. Use the back of the bucket and travel forward to
PUSH the material into the trench or hole.
5.4.5 Excavating
1. Use either the arm or the bucket digging method to
excavate the hole.
2. Plan ahead and dump the bucket far enough away
from the excavation that the material does not fall
back into the hole.
