2. Install the lift cylinder channel locks. Refer to Lift Cyl-
inder Channel Locks, page 16.
3. Remove folding lock pins and store until folded.
4. Set tractor at low idle speed.
5. Engage the fold hydraulics and slowly fold the imple-
ment.
NOTE: On 45-foot drills, the outer wing sections will fold
before the inner wing sections.
6. When folding is complete, insert the folding lock pins pre-
vent the wings from falling. See Figure 2-2.
7. Do not remove the channel locks from a folded drill.
Unfolding the Drill
Unfold the drill on level ground only. Be aware of the clear-
ance required to unfold 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.
IMPORTANT: Never attempt to fold the drill without
first raising it and installing the channel locks or seri-
ous equipment damage will occur.

DANGER!
Electrocution hazard. Machine is not grounded. Electrocution
can occur without direct contact. 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.
1. Remove folding lock pins shown in Figure 2-2. Place
them in the storage rings.
2. Set tractor at low idle speed.
3. Slowly unfold the implement.
4. When the sections are unfolded, hold the lever until
the cylinders extend fully.
Field Operations
To operate seed metering, the in-cab rocker switch must
be on. You do not need to turn the switch on and off while
seeding. A height switch on the implement rockshaft will
automatically turn seed metering off and on as you raise
and lower the drill for field turns.
For normal seeding operations:
1. Check that the in-cab rocker switch is on. The switch
should be lit.
2. Energize tractor hydraulics for fan. Lock hydraulic le-
ver in place for continuous operation. Refer to your
tractor operator’s manual for instructions on operating
hydraulic motor.
3. Run fan for at least 15 minutes before seeding. Hy-
draulic fluid must be warm before fan will operate
properly.
4. Watch the air drill monitor and adjust fan speed by in-
creasing or decreasing hydraulic flow from the tractor.
Use the following guidelines and the fan-speed chart
to properly adjust fan speed.
•
Higher fan speeds improve seed distribution, but high
fan speeds also increase the chance of seed damage
and bounce.
IMPORTANT: 45-foot drills are equipped with a se-
quence valve so one wing will unfold before the other.
When both sections of one wing have completely un-
folded, release and momentarily reverse the lever.
Then re-engage lever to unfold other wing.
IMPORTANT: Always engage the fan with the tractor
at a low engine speed. Engaging the fan when the
tractor is at high speed may cause fan damage.
