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
23. Once the machine has been adjusted and set to the
desired working depth, you may now adjust the gauge
wheels.
Note: The gauge wheels (if equipped) should be set in field
position to be 1/2” to 1 1/1/2” off the ground.
24. Start by loosening set screws on each gauge wheel.
Turn jack handle , to adjust spindle receiver . To
lengthen the spindle receiver (turn counter-clock-
wise), to run wheel closer to ground, to shorten the spin-
dle receiver (turn clock-wise) to run further away from
ground.
25. After adjusting gauge wheel to position needed, re-
tighten the set screws .
