transport wheel is off the ground, back up to provide slack in cable.

LIFT ARM ADJUSTMENT

jam nut. Turn adjustment bolt until lift arm is correctly positioned. Retighten nuts.
Machine must not be adjusted to exceed a maximum S-tine tillage depth of 5” in loose soil
conditions. In hard soil conditions, S-tines must not exceed 3” tillage depth.
HYDRAULIC DEPTH ADJUSTMENT (HDA) OPTION
To set depth, install stroke control collars (purchase locally) on 3-1/2” X 8” stroke (HDA) cylinders lo-
cated on hitch. Collars of identical thickness must be installed on both cylinders. Rephasing cylinders
are used for hydraulic depth adjustment. Do not operate HDA cylinders fully extended. Immediately
after fully raising hydraulic depth adjustment cylinders, quickly lower 1/2”. If hydraulic depth adjust-
ment cylinders are left in fully raised position, they will settle. If machine has settled unevenly, fully
extend hydraulic depth adjustment cylinders and hold hydraulic lever until machine levels. After it
levels, quickly lower 1/2”.
CABLE PULL BRACKETS
Under severe conditions (heavy machine draft due to deep penetration or high eld speed)
cable pull brackets may slide on drawbar wing tube resulting in improper cable adjustment.
The solution to this problem is to relocate cable pull brackets at desired position and then
weld a stop on drawbar next to cable pull brackets.
Never rotate S-tines forward or backward with machine in transport position.
FIELD TO TRANSPORT POSITION
1. Stop in a level area and back tractor up to provide slack in pull cables.
2. Open manual lock valve on auto-fold lock cylinder. Fully extend auto-fold lock cylinder.
3. Fully retract hydraulic depth adjustment cylinders (if so equipped).
4. Hinged wing machines only: Install 1-1/4” hinge lock pins.
5. Fully retract lift cylinders to raise sections.
6. While machine is resting on its transport wheels, drive tractor forward. Wings should fold to
transport position. NOTE: Transport wheels must rotate against “toe-in” adjustment bolts and
follow directly behind knuckles. Transport wheel “toe-in” can be adjusted by moving outside 3/4”
adjustment set screws (8X0665, page 5-5). “Toe-in” and proper lubrication of pivot will make it
easiertounfoldmachineintoeldposition.
7. IMPORTANT: Install transport locks.
Always be sure transport locks are engaged when making adjustments on machine in
raised or transport position.
