Operating Instructions
This section covers general operating procedures. Experi-
ence, machine familiarity and the following information will
lead to efficient operation and good working habits. Care-
fully read the operator’s manual for the air-drill cart you will
be using with the implement. Always operate farm machin-
ery with safety in mind.
General Description
The seed-metering mechanism of this drill is powered by
the cart tire and is driven at a rate proportional to distance
driven. This ensures the rate applied in pounds per acre
remains constant as ground speed varies. The metering
device is driven through an electro-magnetic clutch which
will not engage unless the fan motor is running at operat-
ing speed and the implement is lowered past an adjust-
able height switch. This prevents the primary seed hoses
from being plugged by seed being metered into them with-
out the fan running. It also allows the seed to be shut off
automatically when the drill is lifted on headlands. The
metered seed is carried by air through the five primary
hoses to the distribution towers on the implement. These
towers then divide the air and seed into individual rows.
Prestart Checklist
•
Lubricate the drill as indicated under Lubrication,
“Maintenance and Lubrication,” page 25.
•
Check the tires for proper inflation as listed on the Tire
Inflation Chart, “Appendix,” page 31.
•
Perform all beginning-of-season and daily service items
discussed under “Maintenance and Lubrication,”
page 25.
•
Check the drill for worn or damaged parts and repair or
replace them before going to the field.
•
Check all nuts, bolts and screws. Refer to the Torque
Values Chart, “Appendix,” page 31.
Lifting the Drill
The implement lifting system is equipped with rephasing
hydraulic cylinders in a master-slave configuration. They
must be bled free of air using the procedures listed under
Bleeding the Hydraulics, “Preparation and Setup,” page
12.
Rephasing Lift System
After a period of normal use, the cylinders may get out of
phase. This will cause some implement sections to run
higher than others. To rephase the cylinders:
1. Raise the implement completely and hold the hydrau-
lic remote lever on for several seconds until all cylin-
ders are fully extended. Do this every time you raise
the implement out of the ground.
2. When all cylinders are fully extended, momentarily re-
verse the hydraulic remote lever to retract the system
1/2 inch. This will help maintain levelness.
Lift Cylinder Channel Locks
The lift system has channel locks for the dual gauge
wheels on the center section. See Figure 2-1. Use these
locks every time you raise the drill for maintenance, lubri-
cation, folding or transport. To install the locks, place the
lock channels over the extended cylinder rods and pin in
place.

Folding the Drill
1. Fold the drill on level ground only. Be aware of the clear-
ance required to fold 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 and
lowered or are in the raised position.
•
Stay off of cart walkboard while folding.
•
Keep others away.
!
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.
Fully raise the implement.
