DRILL PREPARATION
GENERAL NOTES FOR FIELD OPERATIONS
Most of the procedures described in this section require
the use of a tractor with three sets of hydraulic remotes.
Before proceeding with the firs time setup, or before mak-
ing any adjustments mentioned in this section, make ev-
ery effort to obtain and hitch a tractor to the drill.
36’ DRILL
minimum of 180 horsepower.
45’ DRILL
minimum of 225 horsepower.
1. Be certain that the drill’s transport wheels and gauge
wheels have the proper inflation as listed on
"Tire Infla-
tion Chart"
2. Load seed box with seed. You should use cleaned
seed to get the best results. You should always have the
drill hitched securely to a tractor, with safety chain con-
nected. Lower the drill before loading.
3. This drill can be transported with a full box of grain. It
is best
NOT
to do this unless necessary because the in-
creased weight does increase the chances for problems
on the road.
DO NOT exceed 20 miles per hour.
4. Calibrate each seed box for a proper rate based on the
seed that you are drilling. Calibration information is locat-
ed on the inside of your box lid or in
"Seeding Adjust-
ments"
on page 5-1. Make sure the seed rate is adjusted
the same across the entire drill.
5. If your drill comes equipped with an acremeter, it
should be mounted on the left gauge wheel axle on the
outboard side. It will accumulate the total acres drilled
with the drill. In order to find out the acres covered, write
down the beginning reading and subtract it from the end-
ing reading for the total acres planted.
6. This Drill is offered in different row spacing widths;
therefore, some of the drill boxes do not have the same
number of seed cups between each internal box divider.
The section with the largest number of cups will tend to
empty sooner.
7. Make sure that the feed cup door adjustment handle
on each cup is set the same across the drill.
8. If you notice excessive cracking on large grain seeds,
adjust all feed cup door handles to a wider setting.
9.
NEVER
back up with openers in ground. If you do,
check all openers to be sure none are clogged.
10. After lowering the drill into planting position, observe
the drill from the side. Check to see that the tongue is lev-
el to the ground. If it is not, a Hitch Height Adjustment is
needed. See "
Tractor Draw Bar Hook-Up
", page 2-3. It
is especially important to check for this if the drill has been
hitched to a different tractor.
11. This drill is not designed to be turned sharply in the
field.
ALWAYS
lift the drill
COMPLETELY
out of the
ground when turning at ends of field rows and other short-
radius turns. If the drill is not completely raised, the lift hy-
draulics will be out of sequence. Refer to "
Tractor Hy-
draulic Hook-Up
12.
NEVER
allow anyone to ride on the drill.
13. Maximum seeding speed will vary according to soil
conditions.
14. Check to see if the drive clutch activators are adjusted
properly. See drive system clutch on page 4-1.
15. You can adjust the tension on each disk opener
spring. This is especially useful in applying more pressure
in tractor tire tracks.
16.
NEVER
unhook drill from tractor with boxes un-
folded and raised off the ground.
NEGATIVE TONGUE
is
present in this position.
!
CAUTION!
ESCAPING FLUID UNDER PRESSURE CAN HAVE SUFFICIENT FORCE
TO PENETRATE THE SKIN.
CHECK ALL HYDRAULIC LINES AND HOSES BEFORE
APPLYING PRESSURE. FLUID ESCAPING FROM A VERY SMALL HOLE CAN BE ALMOST
INVISIBLE. USE PAPER OR CARDBOARD, NOT BODY PARTS, TO CHECK FOR SUSPECTED
LEAKS. IF INJURED, SEEK MEDICAL ASSISTANCE FROM A DOCTOR THAT IS FAMILIAR
WITH THIS KIND OF INJURY. FOREIGN FLUIDS IN THE TISSUE MUST BE SURGICALLY
REMOVED WITHIN A FEW HOURS OR GANGRENE WILL RESULT.

BEFORE OPERATING YOUR DRILL FOR THE FIRST
TIME, MAKE SURE YOU HAVE CHECKED THE FOL-
