rephase the cylinders raise the implement completely up
and hold the lever on for several seconds until all cylinders
are fully extended. This should be done every time the im-
plement is raised out of the ground. Once all the cylinders
are fully extended the hydraulic control should be momen-
tarily reversed to allow the cylinders to retract about 1/2”.
This will help to maintain a level implement.
The implement uses a stroke control valve to control the lift
system hydraulics when lowered. This control is adjust-
able and works with the press wheel adjustments to con-
trol the seed depth, see Setting Seeding Depth and
Leveling Front-to-Rear in the “Adjustments” section on
page 60.
The lift system has transport lock channels for the inner
cylinders. These channels must be used every time the
drill is folded or in transport.
Folding the Drill
!
DANGER!
Overhead crushing hazard - to prevent serious injury or death:
•
Always use transport locks when implement is folded.
•
Fold implement only if fold cylinders and hoses are bled free
of air and fully charged with hydraulic oil.
•
Stay away from frame sections when they are being raised/
lowered or are in the raised position.
•
Stay off of walkboard while folding.
•
Keep others away.
!
DANGER!
Electrocution hazard -
to prevent serious injury or death from electrocution:
•
Keep clear of overhead power lines when transporting, fold-
ing, unfolding, or operating all air drill components.
•
Stay away from overhead power lines when positioning auger.
Machine is not grounded. Electrocution can occur without di-
rect contact.
1. Folding is to be done on level ground only. Be aware of
the clearance required to fold the drill. Do not fold drill
where it may come in contact with obstructions or near
overhead lines. Keep all persons clear of this area.
2. Raise the implement fully.
3. Install the lift cylinder transport lock channels.
4. Remove folding lock pins and store until folded.
5. Set tractor at low idle speed.
6. Engage the folding system hydraulics and slowly fold
the implement. On 45’ drills the outer wing sections
will fold before the inner wing sections.
7. When folding is complete insert the folding lock pins in
place to prevent the wings from falling, refer to Figure 3-
10.
8. Do not remove the lift wheel cylinder lock channels
from a folded drill.
Unfolding the Drill
!
DANGER!
Overhead crushing hazard - to prevent serious injury or death:
•
Always use transport locks when implement is folded.
•
Fold implement only if fold cylinders and hoses are bled free
of air and fully charged with hydraulic oil.
•
Stay away from frame sections when they are being raised/
lowered or are in the raised position.
•
Keep others away.

ing, unfolding, or operating all air drill components.

rect contact.
1. Unfolding the drill is to be done on level ground only.
Be aware of the clearance required to unfold the drill.
Do not unfold the drill where it may come into contact
with any obstructions or overhead lines. Keep all per-
sons clear.
2. Remove folding lock pins, refer to Figure 3-10, and
place them in the storage rings.
3. Set tractor at low idle speed.
NOTE: Never attempt to fold the drill without first rais-
ing it and installing the gauge wheel lock channels or
serious equipment damage will occur.
