OPERATING THE DIGGER
DIGGING A HOLE
Position the tractor with the implement alongside the digging
area, and lower the lift links completely.
Fig. 1
With the spade carriage in the retracted position, set the
spades at the maximum angle of inclination (fully out, see
"starting position"). Set the spades in rotation to begin
excavating the hole, and operate the sideshift to extend the
carriage (the spades will push the soil away from the starting
position).
Fig. 2
Retract the spade carriage without stopping the rotary motion.
Reduce the inclination (A) of the spades (as far as the
consistency of the soil will allow), and as the next stroke
begins, operate the sideshift again to extend the carriage, then
return the spades to the maximum angle (B).
Fig. 3
Retract the spade mechanism as before (again without
stopping the rotary motion). Reduce the inclination (A) of the
spades partly or totally for the next stroke (as far as the
consistency of the soil will allow).
Operate the sideshift again to extend the carriage, and at the
end of the stroke, return the spades to the maximum angle
(B).
NOTE: If the intention is not to empty the hole completely but
to leave a certain amount of soil in place, do not return the
spades to the maximum angle (B), instead, stop the rotary
motion and raise the implement with the lift links before
retracting the carriage.
