21. Situations that may require the operator to angle the
gangs would be in a field that requires the unit to be
more aggressive as far as moving soil such as level-
ing ditches, filling in sprayer tracks, more aggressive
weed control, etc. In these instances, the gangs may
be angled as needed to level the ground and remove
problem weeds. In the fall, the gangs would be
angled to make the unit more aggressive to cover
more residue. This will tie the residue to the surface
and enhance the breakdown of the residue. Also in
very hard ground, the angled gangs will allow the unit
to penetrate better.
22. The Turbo Max is a versatile tool that allows the oper-
ator to make changes from the cab of the tractor. It is
important to remember the relationships between
gang angle, speed and wing down pressure. When
operating the gangs at an angle, slow down (6-8
mph) and set wing fold system to "FLOAT". When
operating gangs in the straight position, speed up (8-
10 mph) and set the wing fold system to active
hydraulic down pressure.
Gauge Wheel Adjustment
Refer to Figure 33
Note: Gauge wheels are not necessary on all machines.
Rolling terrain or terraced ground are conditions that
may require a gauge wheel. The gauge wheels
should never be in constant contact with the ground.
They should operate at a position 1/2” to 1 1/2”
above the ground.
23. Once the machine has been adjusted and set to the
desired working depth, you may now adjust the gauge
wheels.
24. Start by loosening set screws on each gauge
wheel. Turn jack handle , to adjust spindle receiver
. To lengthen the spindle receiver (turn counter-
clockwise), to run wheel closer to ground, to shorten
the spindle receiver (turn clock-wise) to run further
away from ground.
25. After adjusting gauge wheel to position needed, re-
tighten the set screws .
26. If the overall depth of the machine is adjusted, espe-
cially if it is set deeper, remember to readjust the
gauge wheels.
