3. When you have machine level and set to the desired
working depth, set the depth stop
on the depth stop
tube . This is located at the front of the machine. This
will maintain a constant depth each time after raising
and lowering machine.One full turn of the handle
will
change the depth approximately 0.64cm (0.25in).
Note: If after setting the depth stop, the detent on the trac-
tor kicks out before the stop contacts the button on
the depth stop, slow the hydraulic flow speed down. If
this problem exists, contact the factory service repre-
sentative for other possible adjustments. On tractors
with a timed detent setting, set the detent so when
you raise the machine, the pump will run for 1/2 to 1
full second after full raise. If it runs longer than this,
damage to the seals of the lift cylinders may result.
Refer to Figure 33
4. Once the machine is set, running level both fore and
aft, from side to side you are ready to run. The first
part of the machine that makes contact with the soil is
the turbo coulters. These can be adjusted hydraulically
from the seat of the tractor. These coulters are
designed to cut and size, they will also help with bury-
ing residue as the aggressive turbo blades will pick up
and roll the soil.
Note: These coulters should not be run at a depth deeper
than 5”. Also, in very hard ground, be careful to try
not to force the coulters too deep as it may try to raise
the front of the machine out of the ground as this will
affect the overall performance of the machine.
5. The machine can be equipped with several different
shank options. It is important to understand these
options and how they affect the soil. See a and b for
description.
a. Toggle Trip Shanks with 7” winged point. These can
run up to 11” deep and with winged points, they do an
excellent job of fracturing the soil. These shanks run 3”
deeper than the rear row of shanks. In certain condi-
tions, such as spring chiseling, shallower chiseling
depths are desired. The front shanks can be adjusted
up 3” so they are at the same operating depth as the
rear shanks. This will allow 6-8” chiseling depths with
all shanks operating at the same depth.
