BULLDOZING
DOZER EXCAVATION
When dozing out a pit with a blade or bucket, make
cross cuts working from South to North in overlapping
swaths. When the bucket or blade fills, lift and push
contents over the undug ground which will later be dozed
to the opposite side and then out.
You have to work down from ramps on either side of
opening until the desired depth and area are achieved.
You should leave one ramp intact so that trucks can
deliver foundation materials where they will be used. If
soil is excessively hard, loosen it with a ripper or plow.
The remaining ramp can be cut out with either a backhoe
or by hand.
When regular loading tools are not available it is possible
to utilize bulldozers for filling tracks and trailer. Inclined
ramps, built of earth, steel or wood, are a means to assist
loading economically when level terrain predominates.
DOZER DITCHING
A dozer and blade can dig wide, shallow ditches
effectively as shown in the following illustrations. When
the limits for side excavation are reached (A)...
...the unit can work in the trench pushing the material
forward into mounds (B), that can then be pushed to the
side (C).
