15. Refer to Figure 17. Once the machine is level and set to
the desired depth, set the depth stop
at the front of the
machine to ensure that the unit will operate at a consis-
tent depth every pass. After setting the stop, if a change
of depth is desired, 1 full turn of the handle
either in or
out will change the depth approximately 1/4” up or down
respectively.
Note: Slight tire to ground pressure should be maintained to
prevent cylinder pin and clevis wear. If after setting the
depth stop, the detent on the tractor kicks out before the
stop contacts the button
on the depth stop, slow the
hydraulic flow speed down. If this problem exists, con-
tact the factory service representative 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.
16. Varying the angle on the gangs will also change the
results of your operation. It is recommended to operate
the Turbo Max with the gangs in the straight position
when this is your last pass ahead of the planter or grain
drill. This will leave the best possible seedbed for plant-
ing. It is not recommended to operate the tool at a depth
deeper than the intended planting depth.
17. 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 leveling 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.
18. The Turbo Max is a versatile tool that allows the operator
to make changes from the cab of the tractor.
