1 . The
combination hitch can be
used as either a single
strap or
clevis hitch as shown in figures 1
and
2. The bolt holes in the hitch
have been offset vertically so the
hitch can be turned over and
bolted·at two height locations on
the tongue.This makes it possible
to havefourhitch heights for both
the single strap and the clevis
hitch. HITCH HEIGHT SHOULD

WHEN DRILLING.
2 . The tonguejackmakes itpossible
to raise orlowerthe hitch as need-
ed for tractor hook-up. Always
return jackto itshorizontal storage
position on top
of tongue slide
beforefolding drill (see fig.3and 4).
3. Onceyou have the hitch pin in place(1" DIA. MINIMUM SIZE PIN) and the jack in storage position, you are ready to
hook up your hydraulic hoses. You need a dual hydraulic system. If this is the first time you have had fluid in the
systems, you should use the following procedure:
a. Hook Hydraulic hoses to tractor outlet.
b. Loosen both connections on one cylinder.
c. Slowly work hydraulic lever back and forth.
d. When fluid begins to come out of one hose, tighten that connection.
e. When fluid begins to come out of the other hose, tighten that connection.
f. Repeat above process
on each cylinder.
g. Check tractor hydraulic reservoir fluid level at this time. You will probably have to add some hydraulic flUid.
(See detailed drawings of hydraulic system in Parts Manual.)
4. If wing cylinders do not operate properly, clean out small orifice in fittings circled on wing cylinder illustration
(see fig.

6). open during transport.
3. Check to see if you have the required 60 Ibs. of pressure in the four transport tires (Gauge wheel tires should have
45lbs.~
4. Do you have the proper highway warning devices to satisfy all federal, state and local highway safety laws?
CAUTION: THIS DRILL SHOULD NEVER BE PULLED FASTER THAN 20 MILES PER HOUR.
UNFOLDING
1. Remove pin from pull·bar transport lock (see fig. 7). This must
always be used when moving the drill in folded position.
2. Unfold boxes using hydraulic cylinders. Do this very slowly and
carefully. Seriousdamagecouldoccurifdone fast and carelessly.
Folding and unfolding is best achieved
on level ground.
3. Apply hydraulic pressure to the raising and lowering system.
Raise the drill
to free up the transport lockpins for removal (see
fig.
6). Place pins into storage position (see fig. 8).
FOLDING
1. To fold the drill, reverse the order of the unfolding instructions.
Be sure all transport devices as shown in figures 6 and 7 are in
place before transporting.
2. When folding the boxes, the pull bar brackets should slide
smoothlytogetherintothestabilizerwing on thetongue (see fig. 10).
If they scrape the wing, the boxes can be raised or lowered by
adjusting the wing turnbuckle (see fig.
9).

Place the drill on a level seedbed typical to your planting soil and unfold the
boxes.
At the top ofboth vertical tubes on thetransportframe is athreaded studand
jam nut
(see fig. 11). Make sure both studs have approximately the same
length
of threads extending above the jam nut (5 inches) toinsure that the lift.

PUT THE TRANSPORT PINS IN STORAGE POSITION
(see fig. 8). Slowly lower the drill until it is firmly on the
ground and

Figure 12
Leveling the Drill Top Slide
Cylinder
The opener spring rods located along the back of the drill boxes are indicators of the level of the drill because they
show the amount of down-pressure exerted
on the disk openers. A level drill will have equal opener down-pressure
from end to end. Check the spring rod cross bolts to see that they are all extending about 1 to 2 inches above their
spring rod castings (see fig.
13). This is a general dimension and may vary with the spring down-pressure you require
for different soil conditions and planting depths (see Opener Depth
Adjustments).
If all the spring rods along the drill extend the same distance above their
castings, the drill is level and you should tighten down the threaded studsas
describedin''TransportWheel AdjustmentsforLeveling and Depth"onpage
5.
If the spring rod extensions vary in length, the drill can be leveled with
transportwheeland gaugewheel adjustments.Thesearedescribed
on page 5.
NOTE: Transport wheel and gauge wheel adjustments for leveling the drill
raise
or lowerthe drill box, causing openerand seed planting depth changes
atthe centerand ends
of thedrill.Forindividual diskopeneradjustmentssee

Transport Wheel Adjustments for Leveling and Depth
When leveling your drill, opener spring rods near the center of the drill that extend higher above their spring rod
castings than desiredcan
be adjusted byraising the transport frame. This isdone by raising thedrillwiththe hydraulic
lift cylinders. Spring rods nearthe centerthatdon'textend high enough are adjusted by lowering the transport frsme
(raising thetransportwheels
by retracting thecylinders). ONCE THESPRING RODS AREATTHE DESIREDSETIlNG,
screw the threaded studson top of thevertical tubes(see fig. 11) downasfaras possibleand securethemwiththejam
nut.
This adjustmentwill stop the liftcylindertravel at the same pointeach time theboxes are lowered fordrilling and
assures accurate seed depth control.

Gauge Wheel Adjustment for Leveling and Depth
The openers near the outside of the drill are adjusted by raising or lowering
the gauge wheels.
Raise the drill
out of the ground and loosen the jam nut located near the
bottom clevis of the gauge wheel adjustment arm (see fig. 14). This arm is
( threaded to allow easy opener seed depth adjustment.
By lengthening the
\ arm the gauge wheel is lowered, causing less penetration of the openers and
lessspring rod extension
for leveling. Byshortening the arm thegauge wheel
is raised, causing deeperpenetration
of the openers and the spring rods will
extend higher. Afteradjusting, be sure the arms on both gauge wheels have
the
same length of threads showing.

INDIVIDUAL OPENER ADJUSTMENTS
Press Wheel-Opener Unkage Depth Adjustment
When using the press wheels as rigid-mount depth con-
trol wheels, the depth of eachopeneriscontrolled by the
position
of the press wheel. There are several holes on
the press wheel spring rod for varying the height
of the
press wheel.
By removing the adjustment pin and raising
thE!" press wheel in relation to theopener, deeper penetra-
tion isprovided (see fig. 15). The press wheel islowered if
less penetration is desired.
Spring Tension Setting
Each opener spring can be adjusted
for tension.
This is useful when
penetrating hardsoil and for planting
in tractor tire tracks. To adjust the
tension, remove the 'W" clip at the
bottom
of the spring and place it in a
higher hole
for more tension and in a ''W''
Clip
lowerhole for less tension (see fig. 16
and 17). If too much penetration is
achieved at
the lowest tension set-
ting,
completely remove the "W"
clips. Figure 16

PRESS WHEEL ADJUSTMENTS
1. Press Wheel Spring Location

\ The press wheels are designed to perform two different functions: they can be set as either independent spring.
(
loaded firming wheels or as rigid-mount depth control firming wheels.
Toachieve the spring·loaded action, the press wheel spring must be set.below the mounting barandthe cotterpin
on
top of the bar (see fig. 18). The press wheel spring rod hasseveral holesin it for varying thespring pressureatthepress
.. wheel. When using rubber·tired depthcontrol wheels on the opener, the press wheels shouldalwaysbe set for spring.
. loaded firming action.
Toachieve the rigid-mount depthcontrol action, the cotterpin
must beset belowthe mounting barwith thespring on
top. This spring prevents the presswheel from dropping when the drill
is raised and providesa placetostore the press
wheel spring (see fig. 19).

2. Press Wheel Angle Adjustment (Double-V Press Wheels Only)
Adjustment Pin
Figure 20
Figure 21
7
The camber angle of the double-V press wheels may be
adjusted by removing the angle bar adjustment pin and
moving the angle bar. Moving the angle bar forward will
cause the press wheels
to pull more soil over the seed
(see fig. 2O). Moving the angle bar back will cause the
press wheel
to pull less soil over the seed (see fig. 21).

SEEDING ADJUSTMENTS
1. Rotate each gauge wheel to see that feed cups and drive are working properly and are free from foreign matter.
2. To adjust your seeding rate, first you must decide which sprocket arrangement you need (see seeding chart). 'In (
order to change sprockets, remove nut in center of double speed change sprocket and tum sprocket over. Loosen
the idler arm bolt, put chains on and tighten both bolts. (The chains need to be reversed to make this change.)
3. There are many factors which will affect seeding rates: seed treatment, weight of seed,size of seed, surfacecondi-
tion of seed, and tire configuration, pressure and slippage. Minor adjustments will probablybe needed to compen-
sate for the above factors.
4. The pounds-per-acre in the seed charts are based on drills having 9.5L x 15 inch rib implement gauge wheel tires
with 45 Ibs. of air pressure.
5. The large differences in seed size and treatment can cause a wide variation in actual seeding rates. The seed rate
charts on the following pages are based on average size seed.This may differ from the seed you are using. Use the
seed rate
charts as a guide. Set the pounds-per-acredesired at theindicator number for your row spacingand com-
plete the following procedure to calibrate the drill for your specific seed.
a. Place several pounds of seed over three of the feeder cups at the outboard end of the drill box.
b. Pull the seed tubes
out of these three disk openers.
c. Raise the drill off theground. Besure to insert transport lock pinsinslide tubes to preventinjuryshould hydraulic
system
allow drill to lower while working around it.
d. Place a container underthe three seed tubes to gather the seed as it is metered.
e. Rotate thedrivegaugewheel until one acre hasbeen tallied on theacremeter. This will beapproximately 250 rota-
tions on a 24'drill and approximately 200 rotations on a 30'drill. Be sure to check the three feedercups to make
sure each cup has
plenty of grain coming into it
f. Weigh the seed which hasbeen metered. Divide by three.This will give you the ounces/pounds metered by each
feeder cup. Multiply by the number
of openers on your drill to arrive at the total pounds-per-acre yourdrill would
meter
at that setting. If this figure is different than desired, set your feed cup adjustment lever accordingly.
Repeat procedures a
through! on each drill section.
6. You may
want to repeatthe calibration procedure if the results of your calibration vary greatly from the suggested
settings contained in
this manual.
Remember: Tire size and field
conditions will also affect seeding rates. Be certain that yourgauge wheel tires are
9.5Lx
15 and that they are inflated to 45lbs. When drilling, check the amount of seed you are using by noting acres
drilled,
amount of seed added to drill, and level of seed in drill box. Ifyou suspect that you are drilling more or less
seedthan desired, and you have accuratelycalibrated
the drill to your seed, you may need to adjust the seedingrate
slightly to compensate for your field conditions.

AELD OPERATIONS
1 . 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 before loading.
2 . This machine can be transported with a full
box of grain. It is best NOT to do this unless necessary because the
increased
weight does incresse the chances for problems on the road. DO NOT exceed 20 miles per hour.
., 3. Never back up with openers in ground. Ifyou do, check all openers to be sure none are clogged.
4. Never allow anyone to ride on the machine.
5. Maximum drilling speed varies upon soil conditions.
6. If yourdrill comes equippedwith an acremeter it should be mounted to theleftgaugewheel. It will accumulate the
total acres drilled with the machine. In order to find out the acres covered, write down the beginning reading and
subtract
it from the ending reading for the total acres planted.
7. You can adjust the tension oneach diskspring. This is especiallyuseful in applying morepressure in tractortracks.
MAINTENANCE SERVICE
PROPER SERVICING AND ADJUSTMENT IS THE KEY TO THE LONG UFE OF ANY FARM IMPLEMENT. WITH
CAREFUL AND SYSTEMATIC INSPECTION OF OUR GRAIN DRILL, YOU CAN AVOID COSTLY MAINTENANCE,
TIME AND REPAIR.
1. After using your drill for several hours, check all bolts to be sure they are tight.
2. Lubrication-listed below are the items you need to lubricate every 12-15 hours of operation:
a. Gauge wheel bearings.
b. Jack shaft bearings.
c. Feeder cup drive sprocket bearings.
d. Oil all roller chains. This is important to do before putting the machine in storage.
e. Feeder cup drive sprocket should be oiled in its square bore. Move feeder cup adjustment lever away from the
sprocket as faras possiblein order
to gettheoil back into thesquare.This is most important to dobeforeputting
the machine in storage.
f. Post top roller shaft.
g. Box post lower spindle and cross tube on main frame_
h. Telescoping axle tube lower roller between transport tires.
i. Telescoping axletoprollerslocated inside at top of vertical tubeon trsnsport frame(drill must be lowered to reach
lube fitting).
3. Disk scrapers should be kept properly adjusted.
4. Always maintain 45 Ibs. of air pressure in gauge wheel tires and 60 Ibs. in the transport tires.

PROBLEM
1. Uneven seed spacing or uneven
stand
TROUBLE·SHOOTING
SOLUTION
a. Check for trash in seed cup.
b. Check to see if seed tubes are plugged.
c. Reduce ground speed.
d. Check opener disks
to see that turn freely.
e. Use faster drive speed (See page 8, No.2) and close feed cup flutes to a
more narrow position.
2. Opener disks not turning freely. a. Check for trash or mud build-up on disk scraper. Readjust scraper.
3. Actual seeding rate is different
than desired.
4. Excessive seed cracking
5. Acremeter doesn't measure
accurately
6. Uneven seeding depth
7. Press wheel not compacting
the soil
as desired.
8. Grain box not emptying evenly
b. Check to see if scraper is adjusted too tight and isrestricting disk
movement.
c. Check disk bearings and flanges.
d. Check opener frame for possible damage.
e. If opener disks turn freely by hand but not in field, lessen down pressure
on disk opener.
See Operator's Manual, page 6.
a. Check tire pressure. Proper inflation is 45 Ibs. in gauge wheels and
60 Ibs. in transport tires.
b. Check tire size. Proper size is 9.5L x 15.
c. Uquid seed treatment will affect seeding rate if the chemicals build up
in seed cup. Unless cleaned regularly, this build up can cause breakage
of the feed shaft.
d. Check drive range. See Operator's Manual, page
12.
e. See Operator's Manual, page 8 for instructions on calculating seed rate.
a. Slow drive speed and open flutes in feed cup to a wider position. See
page 8, NO.2.
a. Check tire pressure. Proper inflation is 45 Ibs. in gauge wheel tires and
60 Ibs. in transport tires.
b. Check tire size. Proper size is 9.5L x 15.
c. Check planting operation for excessive overlap or gaps between passes.
d. Loose soil conditions and slippage will cause variations in acres
registered.
e. To check accuracy of acremeter, raise drill out of ground. Note acreage
figure on acremeter; rotate
the gauge wheel approximately 200 times for
a: 30'drill or approximately 250 times for a 24' drill. This should register
one acre.
a. Check box leveling adjustments; Operator's Manual, page 4 and
5.
b. See depth setting instructions, page 5 and 6.
a Reset press wheel height, page 6 and 7.
b. Convert press wheel spring setting to bottom position which gives in·
dependent press wheel action if desired. See Operator's Manual, page 7.
a Certain model drills do not have the same number of seed cups
between each divider
or bulkhead. The section with the larger number of
cups will
empty sooner.
b. Check adjustment levers on each box to see that they are set on same
indicator number.

wheels becoming packed
with mud
12. Improper folding of drills
TROUBLE·SHOOTING (Con't)
SOLUTION
a. Drilling in damp or wet conditions may increase this problem.
b. Openers may be moved from a staggered to an in·line position to
reduce trash thrown from front openers into rear openers.
c. Reduce down pressure on
o;:>eners.
a. Check all hose fittings and connections for air and oil leaks.
b. Check tractor hydraulic oil level. If conditions persists, have your dealer
service department check sequencing valve.
a Install scrapers.
b. Reduce spring tension on openers.
c. Be sure press wheel springs are in independent position. See Operator's
Manual, page
7.
a Adjust wing adjusting link as shown on page 3 of Operator's Manual.
b. Check hydraulic system for air and oil leaks.
c. Clean
out small orifice fittings in wing cylinders. See page 2 of
Operator's Manual.
d. Make sure
that the wing boxes unfOld to a straight line. Check to see
that both pull bars are attached to the boxes at exactly the same
