General Operation and In-Field Adjust-
ments
Prior to Operating the Turbo Max
11. Raise the machine fully so the lift cylinders no longer rest
on the transport lock channels , Refer to Figure 15.
Remove transport lock channels and store on the bars
above.
Hitch Turnbuckle
Note: If possible have someone observe the machine during
the initial operation for levelness - both front to rear and
center to wings. Adjust each as needed.
Refer to Figure 16
12. For front to rear, either extend or shorten the front turn-
buckle on the leveling system by loosening jam nut
with turnbuckle wrench (stored on rear pegs of hitch).
Adjust turnbuckle until level front to back. Re-tighten
jam nut after machine is level. Never run the machine
lower (deeper) in the rear than in the front.
13. The Turbo Max may be operated with the gangs run-
ning from 0-6 degrees. Changing this angle does affect
the operation of the unit in a couple of ways. As indi-
cated above, if the blades are operated at an angle,
down pressure is generally unnecessary. Also, operat-
ing speeds will need to be less when operating with the
blades angled 3-6 degrees. Operating speeds should
be from 6-8 mph when operating gangs in the angled
position and from 8-10 mph when operating in the
straight position.
14. In a first time operation, it is generally best to operate
the unit at a slight angle to the rows. If the unit is used
as a secondary pass it is recommended to operate the
unit at a slight angle to the previous tillage pass. This
will improve trash flow and increase the leveling capa-
bility.
