CONTINUOUS TRENCHING WITH SPACED BELL-
HOLES
Begin by digging the trench to the desired grade.
Progress along the trench to the bellhole locations and dig
as much of the bellhole as possible without moving the
backhoe from the trench line setting.
Move to the side as previously described and com-
plete the bellhole. Realign the backhoe with the trench,
and proceed trenching to the next bellhole.
When finishing straight walls or bellholes in sandy soil,
use a platform under the rear of tracks and the stabilizers.
The platform distributes the load over a larger area and
lessens the possibility of a cave-in. The platform also
tends to keep the unit from creeping rearward if hard dig-
ging is encountered.
DIGGING STRAIGHT WALL SHALLOW BASEMENTS
Begin at one corner, removing a much material as
possible to grade level. Then, reset the unit forward and
continue digging to grade. Progress around the edge of
the basement, finishing each corner as you come to it.
DIGGING UNDER A SIDEWALK OR CURB
To continue a trench or excavation under a sidewalk
or curb, position the backhoe as shown.
GRAVE DIGGING
For the best grave digging position, back the tractor
straight in toward the grave site.
