Front to Rear Leveling (Hydraulic Option):

1) Completely unfold the machine while observing the

unit for any hydraulic leaks or loose fittings.

2) Once unfolded, raise the unit to re-phase the lift cir-

cuit. Hold the lift circuit open for 30 seconds to ensure

all air is purged from the hydraulic system.

3) Lower the machine so the front coulter gangs are

1-2" off of a level surface.

4) Using the (yellow) hydraulic hoses, adjust the

hydraulic cylinder so that the front coulter gangs are

the same distance off the ground as the rear coulter

gangs.

Level Bar Spring Adjustment:

1) To adjust the level bar spring assembly to the fac-

tory setting of 26 5/8", loosen the jam nut (3).

2) Adjust the nut (4) until the 26 5/8" dimension is

reached between the backside of the spring guide

and front side of the level bar spring rod plate.

3) Once 26 5/8" is achieved, re-tighten the jam nut (3).

Wing Adjustment Turnbuckle:

Note: Prior to leveling the wings, ensure that the

machine is level front to rear.

1) Lower the machine until the coulter gangs are 1-2"

off of the ground.

2) Loosen the jam nuts (5), and adjust the wing turn-

buckles (6) (shortening the turnbuckles raise the

wings and extending the turnbuckles lowers the

wings) to match the center frame.

3) Once the machine is leveled side to side, any fur-

ther adjustment in the field should be down with the

hydraulic down pressure.
