Level Bar Spring Adjustment
Refer to Figure 12
12. To adjust the level bar spring assembly to the preset
position of 26 5/8”, loosen 1 1/2 jam nut with turn-
buckle wrench (stored on rear pegs of hitch).
13. Adjust the 1 1/2 nut until the 26 5/8” dimension is
reached between backside of spring guide and front
side of level bar spring rod plate .
14. Re-tighten the 1 1/2 jam nut to secure.
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,
