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 25.

Remove transport lock channels and store on the bars

above. Remove the wing transport pins Refer to Figure 26

and store in the spools on the wing rest bar. Open the

wing fold valve located under the depth stop bracket.

12. Unfold unit being sure that the fold cylinders are fully

extended. You may increase ﬂow rates during the folding

and unfolding procedure but be sure to slow the ﬂow rates

back down once the unit is unfolded.

13. When operating the Turbo Max with the blades running at

an angle, it is generally unnecessary to operate with

hydraulic down pressure to the wings. Only in very hard

ground will down pressure be needed. If down pressure is

needed, see “Hydraulic Down Pressure” on page 21 for

initial setup, If no down pressure is needed, set the fold

hydraulic system to the "FLOAT" position at this time.

14. When operating the blades in the straight position, down

pressure is necessary, usually between 200 and 400 psi.

Note: Never leave tractor valve centered when unfolded with

machine in motion. Machine damage may occur when

wings ﬂex. The hydraulic down pressure cylinders have

no wing ﬂex capability and oil ﬂow is required when the

wings ﬂex up or down. You must have the tractor fold hy-

draulic lever in continuous downward ﬂow or “FLOAT” po-

sition before the wings can ﬂex over terrain in the raised

or lower lift position.

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 27

15. 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.
