•
At first, adjust fan speed to the high end of the range
suggested in the chart below. Watch for excessive
seed cracking and seed bounce from the furrow, then
reduce fan speed if necessary.
•
Follow the fan speed chart on page 18 as a guide. Ac-
tual fan speeds will vary with seeding rates, implement
width, row spacing, seed weights and seed size. In-
crease fan speed for narrower row spacings and
heavier seeds and seeding rates. Reduce fan speed
for wider row spacings, lighter seeding rates and seed
more prone to cracking.

5. Pull forward, lower drill and begin seeding. If the me-
tering system does not turn off and on as the imple-
ment is raised and lowered, refer to Electric Clutch
Height Switch, “Adjustments,” page 22.
6. When finished seeding, turn the in-cab switch off be-
fore transporting.
Opener Operation
•
Never back up or turn sharply with openers in the
ground. Doing so may plug or damage equipment.
•
Be aware of a five- to 10-foot delay needed for the seed
to reach the openers. If you stop in the middle of the
field, lift the drill and back up 10 feet before proceeding.
•
Check periodically for plugged openers and hoses. With
the fan running, hand crank the metering system. Look
below each opener for seed or fertilizer. Do not crawl
among the openers unless transport locks are installed,
the implement is securely blocked, and the tractor key is
turned off and removed.
•
The floating-hoe openers give when they encounter ob-
structions. If spring-reset hoe does not fully return to po-
sition, lift the drill out of the ground and allow the spring
to pull opener back down.
To reset shear-bolt openers, replace broken bolts with 5/
16 x 3-inch, grade 5 bolts only (Great Plains part num-
ber 802-131C).
•
See Setting Seeding Depth, “Adjustments,” page 20,
for information on setting seed depth and making open-
er adjustments.
Transporting
!
DANGER!
Electrocution hazard. To prevent serious injury or death from
electric shock, keep clear of overhead power lines when trans-
porting, folding, unfolding or operating all air drill compo-
nents. Machine is not grounded. Electrocution can occur
without direct contact.
!
WARNING!
Towing the drill at high speeds or with a vehicle that is not
heavy enough can lead to loss of vehicle control. Loss of vehicle
control can lead to serious road accidents, injury and death. To
reduce the hazard:
• Do not exceed 20 mph.
• Do not tow a drill that, when fully loaded, weighs more than
1.5 times the weight of the towing vehicle.
!
WARNING!
The implement is designed to hitch to the air drill cart only.
