position of 26 5/8”, loosen 1 1/2 jam nut with turn-

buckle wrench (stored on rear pegs of hitch).

reached between backside of spring guide and front

Wing Adjustment

Refer to Figure 13

15. Once the machine is level fore to aft, the wings may be

leveled. Start by unfolding the wings. Lower the lift cylin-

ders down until coulter gangs are 1-2” off of ground,

both center and wings.

16. Set the wings to match the depth of the center. Start by

loosening jam nut with turnbuckle wrench (stored on

rear pegs of hitch). Turn the turnbuckle to adjust.

(Shorten turnbuckle to run shallower, lengthen to run

deeper), see Refer to Figure 14 for pre-setting the turn-

buckles.

Wing Turnbuckle 586-295S

Refer to Figure 14

17. The wing turnbuckle should be pre-set at 45 3/4” as

shown.

18. Once machine is leveled side to side, any further adjust-

ment in the ﬁeld should be done with the hydraulic down

pressure.

19. If running gangs at an angle and the wings are going too

deep, then you should not run down pressure at all.

Switch hydraulic to the ﬂoat position.

Note: If wings are running too high, increase hydraulic down

pressure setting, too low, decrease down pressure set-

ting. See “Hydraulic Down Pressure” on page 21,
