18. Trenching:
a. The backhoe works well for trech-
ing. Use the arm or bucket method
to dig.
b. Extend the trench between the sta-
bilizers as far as it will go. Be sure
not to undercut the stabilizers and
create a cave-in. Be familiar with
the reach and curl of the bucket.
19. Moving When Trenching:
Follow this procedure when moving to
the next digging position:
a. Swing and dump the bucket. Be
sure it is empty.
b. Retract the boom and bucket and
tuck them up against the rear frame.
c. Raise both stabilizers.
d. Dismount and raise the seat.
e. Transfer to the tractor seat.
f. Slow the engine speed to idle.
g. Turn the hydraulic circuit off or
disengage the PTO clutch and raise
loader (if so equipped).
h. Engage the transmission and drive ahead
a short distance.
i. Lower loader to the ground, set park brake
and place hydraulic control in detent or
engage PTO.
j. Increase speed mid-range PTO RPM.
NOTE
Do not move too far ahead each
time. Moving too far will exceed
the reach of the bucket and the
operator will not be able to form an
even bottom.
