Moving the Trencher
1. One method for moving the Trencher around
the work area is by using the Boom to
push the Trencher across the ground.
WARNING! This technique can be difficult to control
and should only be attempted by an experienced
operator. The stability of the Trencher is dependent
on the stability of the ground; if you choose to move
the Trencher in this way, do so at your own risk. Do
not use the Trencher near ditches or drop-offs.

of ground and press down hard enough
to raise the front legs off the ground.
3. Carefully operate the controls to move the Boom
and slowly roll yourself in the desired direction. Be
certain that the Tires and the new resting places
for the Legs all remain on solid, stable ground.
Maintenance
4. After you have repositioned the Trencher, raise the
Boom to lower the Outriggers back onto the ground.
The procedure can be repeated to move farther.
Operation
