MOVING BOULDERS AND STONE
Dozers can move large rocks on firm ground perhaps
several times its own weight. If the stone is too large for
direct pushing, it can be pushed first on one side and then
on the other.
ROCKS
When a large rock is imbedded in a group of smaller
ones, loosen and remove the smaller ones before attack-
ing the big one. Operators should remember that if a rock
doesn't move, something is holding it. Before proceeding,
find cause and remedy it to prevent machine damage.
Many rocks such as shale and sandstone are found in
tipped position. Always dig under the outcrop, lift, and
break it out rather than try to penetrate from the opposite
side. Sometimes driving a tractor on top will crush such
rocks making removal easy.
STUMPS
Small dozers can tackle big stumps if you dig first.
Make consecutive cuts around the stump until it is loose
enough to pull out by a chain or blade.
Notch the stump and leverage it out using a log or railroad
tie.
