9. Reduce speed of the tractor when transporting over uneven or rough terrain. Avoid all chuck
holes and washboard areas in roads.

10. Reduce speed of the tractor when transporting over hills or steep slopes.

11. When in transport, use accessory lights and devices for adequate warning to operators of other
vehicles and use safety hitch chain. Comply with all Federal, State and Local laws when trav­eling on public roads.

12. Use "Slow Moving Vehicle" emblem for warning vehicles approaching from the rear.

13. When transporting, remember the drill is wider than your tractor and extreme care must be tak­en to allow for safe clearance.

14. NEVER back up when openers are in the ground.

15. ALWAYS set the drill in field position BEFORE lubrication, making adjustments, or servicing.

16. DO NOT lubricate, adjust or repair the drill while it is in operation.

17. DO NOT permit smoking, sparks, or an open flame where combustible lubricants or liquids are
being used.

18. When using treated seed, avoid direct contact with the seed.

19. When using compressed air to clean the drill, wear safety glasses.

20. NEVER unhook drill from tractor when negative tongue weight is present.

!

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 type of injury. Foreign fluids in the tissue must be surgically removed within a few
hours or gangrene will result.

TRACTOR REQUIREMENTS

2-3

A minimum 65 H.P. tractor is required to operate your 13’
End Wheel Drill in most field conditions.

1. One remote outlet is required to operate the drill.

TRACTOR DRAW BAR HOOKUP

When hitching the drill to the tractor drawbar, it is impor­tant to level the drill by adjusting the tongue jack so that
the drill box is parallel with the ground.

The hitch clevis straps can now be adjusted to match the
tractor drawbar height, Fig. 3.

Your drill comes equipped with a hitch safety chain. The
safety chain should be securely attached to the drill hitch
and the tractor drawbar whenever towing or planting.
Pin the drill hitch to tractor drawbar and lower the tongue

using the screw jack. Unpin the tongue jack and move it
to its horizontal transport position on top of tongue.

NOTE: Make sure the hitch is securely bolted to the drill
tongue.

ALWAYS use a pin that contains a safety locking device
to prevent it from falling out.

ALWAYS Attach safety chain from the drill hitch to the
tractorand lock the hook securely onthe chain. Adjust the
chainlength to allow just enough slackto permit turning of
the drill and tractor.

2. Two remote outlets are required if your drill is
equipped with markers.

HYDRAULIC HOOK-UP

Attach the female swivel end of the hydraulic hoses to the
fittings on the cylinder.

You are now ready to hook-up your hydraulic hoses. Ap­ply pipe sealant to the male pipe end of the hydraulic fit­ting and screw the two hydraulic fittings into your cylinder
ports. Then insert hydraulic hoses throughthe spring type
hose loop on the tongue and attach hydraulic male cou­pler tip to hoses. Plug the male coupler into tractor outlets
as instructed in your tractor operators manual.

When using sealant on pipe threads the friction between

the threads is reduced, therefore be certain not to over
tighten causing damage to the cylinder port or fitting.

NOTE: JIC fittings DO NOT require high torque. JIC
and O-Ring fitting do not require sealant. ALWAYS use
liquid pipe sealant when adding or replacing pipe thread
fittings. To avoid possible danger of cracking hydraulic
fittings from over tightening, DO NOT use plastic seal­ant tape.

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 type of injury. Foreign fluids in the tissue must be surgically removed within a few
hours or gangrene will result.

BLEEDING OPENER LIFT HYDRAULICS

4/3/95

This End Wheel Drill requires the use of a 3 1/2" bore x 8"
stroke cylinder with a 20 1/4" {pin to pin} retracted length.

NOTE: Check the hydraulic fluid level in the tractor reser­voirandfilltotheproperlevel. If the bleeding isperformed
with a low tractor reservoir supply, there is a chance of
drawing air into the system. The system capacity is ap­proximately 1/2 gallon and requires 1 pair of remote out­lets.

1. With the transport lock in thetransportposition,referto
"Operating Transport Lock" on page 3-1. Loosen the
connection between the hose end and the cylinder base
end fitting.

2. With the tractor at idle, slowly retract the lift cylinder.
When the air is expelled and oil starts flowing out, tight­en the base end hose connection.

3. Repeat this procedure with the rod end hose con­nection while extending the cylinder.

4. Recheck the tractor reservoir level and add cleanflu­id as necessary.

5. It is advisable to extend and retract the lift cylinder
several times. The majority of air should now be ex­pelled from the system. Any remaining airwill gradually
be pushed to the tractor during day to day operations.

NOTE: If your drill is equipped with markers the marker
bodymust be pinned up for transport. SeeMarker Manual
located in Optional Equipment Section.

HYDRAULIC DEPTH CONTROL

The optional cylinder package purchased with your drill
contains a hydraulic cylinder with depth control stop, Fig.

6. This cylinder allows for a variable adjustment from zero

to maximum stroke which controls the down pressure ap­plied to your disk openers. In order to adjust the stroke of
the cylinder, retract cylinder until the openers are set at
the desired down pressure required. Next, loosen the bolt
on the depth control actuator plate and slide it down the
cylinder until it stops against the plunger of the control
valve on the head of the cylinder. You will now need to ex­tend the cylinder slightly and move the depth control actu­ator plate down to compensate for the control valve
plunger length.

Settingthe seeding rate requires four steps: arranging the
drive sprockets, setting the seed-rate adjustment handle,
positioningtheseed-cup doors, and checking the seeding
rate.

Refer to the seed-rate charts starting on page 5-3. These
chartslist the proper sprocket sizesand seed-rate-handle
settings for various seeds and seeding rates. The seed­rate charts are based on cleaned, untreated seed of aver­age size and test weight. The rates are based on 7.5 x 20
rib implement tires. Many factors will affect seeding rates

CHANGING DRIVE SPROCKETS

Refer to the seed-rate charts for the correct drive type–1,
1A, 2 or 2A. Fig. 9 shows the sprocket arrangement for
each drive type.

includingforeignmaterial, seed treatment, seed size, field
conditions, tire pressure and test weight. Minor adjust­ments likely will be needed. Set and check the seeding
rate using the procedures below, then re-adjust the rate
as necessary.

NOTE: Your drill can beequipped with a special peadrive
(Great Plains part number 152-204A). This drive will in­clude different seed-rate charts.

b. Slidesprockets as necessary and place plastic di-

viders back on shaft between sprockets as neces­sary.

3. Slide idlers on idler arms so they are aligned with cor­rect sprockets. Reinstall chain.

4. Turn idler arm as indicated by drive type to remove
slack from chain. Retighten nut that holds idler arm.

SETTING SEED RATE HANDLE

Position the handle shown in Fig. 12 to the setting indicat­ed on the seed-rate chart. To adjust the handle, loosen
the wing nut under the handle and slide until the indicator
lines up with the correct setting.

POSITIONING SEED-CUP DOORS

For wheat and other small seeds, move the seed-cup­door handles to the highest position. For soybeans and
other large seeds, lower the handles to the second posi­tion. If excessive seed cracking occurs, lower thehandles
to the third position. Move the handles to the fourth, wide­open position for seed-cup clean out. Make sure all han­dles are in the same position before drilling.

CHECKING SEEDING RATE

1. Hydraulically lower the drill to planting position to acti­vate clutch.

2. Check that your tires are 7.5 x 20 rib implement and
properly inflated. Refer to

3. Weigh an empty container large enough to hold the
seed metered for one acre.

4. Jack the drive (left) end wheel off the ground. Rotate
the wheel to see that the drive system is working properly
and seed cups are free from foreign material.

5. Place several pounds of seed over three seed cups on
an outside end of the drill box. Pull the seed tubes off of
these three openers.

6. Turn thedrivewheelseveraltimestofilltheseedcups.
Turn the wheel until seed drops to the ground from all
three cups.

7. Place a container under the three tubes to gather me­tered seed.

Seed-Cup-Door Handle

Fig. 13

8. Rotate the drive wheel until one acre has been tallied
on the acremeter. This will be about 348 rotations. Check
that the three seed cups have plenty of seed coming into
them.

9. Weigh the metered seed. Subtract the initial weight of
the container. Divide by three. Multiply by the number of
openers on your drill to determine total pounds-per-acre
seeded. If this figure is different than desired, reset
sprockets accordingly.

NOTE: You may want to repeat the calibration procedure
if your results vary greatly from the seed-rate chart.

10. When drilling, check the rate by noting acres drilled,
amount of seed added to drill and seed level in drill box.
If you are seeding more or less than desired, adjust the
rate slightly to compensate for field conditions.

GRANULAR FERTILIZER OPERATING INSTRUCTIONS

6-1

Great Plains fertilizer drills have a center seed/fertilizer
partition.This allows approximately the same seedcapac­ity as fertilizer, Fig. 14. The partitions are removable pan­els to allow the drill to be used with all seed, Fig. 15.

If fertilizer is not being used with grain, remove the chain
from fertilizer drive sprocket to eliminate unnecessary
wear on the fertilizer drive system. If total box capacity is
desired for grain, remove seed/fertilizer doors, Fig. 15.
Setfertilizerrateadjustmentleverat“0”to avoid seed loss
through the fertilizer outlets.

The fertilizer rate is set by the adjustment handle located
on the fertilizer tray. The setting that the handle is set on
corresponds to the fertilizer application chart setting num­ber.

The application rate of dry granular fertilizer is affected by
many factors: type, density, relative humidity, and the
moisture content of the material itself. Due to these vari­ables, the chart below should be used only to closely ap­proximate the amount of fertilizer being applied.

If you are applying fertilizer that has a density other than this, use the following table:

Density 45 50 55 60 65 70 75 80

Conversion Factor 1.45 1.30 1.20 1.10 1.00 0.93 0.87 0.81

EXAMPLE: You’re using fertilizer with a 75 lb/cubic foot density and you desire a rate of 100 lbs/acre. Multiply 100 x

0.87 = 87 lbs. Therefore, use the setting closest to 87 lbs.

FERTILIZER DRIVE

4/8/99

The fertilizer feed speed is directly related to your ground
speed so there are no chains or sprockets to adjust in or­der to change your rate. The rate is controlled by fertilizer

outlet opening size. For fertilizer rates see that section of
your manual.

PRESS WHEEL DEPTH ADJUSTMENT

The depth of each opener can be adjusted by the position
of the press wheel, Fig. 16. You can adjust your press
wheels up or down to achieve the correct seeding depth.

With the drill level and openers lowered to planting posi­tion, adjust the knob and adjustment trunnion located
above each press wheel. This will vary the height of the
press wheel which automatically changes the seeding
depth of the opener. Simply rotate the knob until the seed­ing depth is correct.

PRESS WHEEL ANGLE ADJUSTMENT {2 x 13 DOUBLE “V” PRESS WHEELS ONLY}

The camber angle of the 2" x13" double "V" press wheels
may be adjusted by removing the angle bar adjustment
pin and moving the angle bar. Moving the angle bar for-

wardwill cause the press wheelstopull more soil over the
seed, Fig. 17. Moving the angle bar back will cause the
press wheel to pull less soil over the seed, Fig. 18.

INDIVIDUAL OPENER SPRING PRESSURE SETTING

4/8/99

Each openerspring can be individually adjusted for down
pressure. This is useful when penetrating hard soil and
for seeding in tractor tire tracks. To adjust the pressure,

11199

"W" Clip In Lower Position - Less Down Pressure

SEEDING IN TRACTOR TIRE TRACKS

When openers follow in tractor tire tracks and adjusting
the spring pressure on the openers does notgive satisfac­tory depth, Fig. 21, the opener lift arms at the top of the
spring rods can be turned over and bolted on the under­side of the square lift shaft, Fig. 22. Be sure to adjust
spring pressure after making this change.

1. Be certain that your drill tires are 7.50 x 20 and that they are inflated to 28 PSI.

2. Load seed box with seed. Cleaned seed is recommended to get the best results.

3. This machine can be transported with a full box of seed. It is best NOT to do this unless necessary because the
increased weight does increase the chances for problems on the road. DO NOT EXCEED 20 MILES PER HOUR.

4. Your drill comes equipped with an acremeter and it should be mounted on the left end of the jackshaft. 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 end reading for the total acres planted.

5. Make sure that the seed-cup-door handle on each cup is set the same across the drill.

6. If you notice excessive cracking on large grain seeds, adjust all seed-cup-door handles to a more open setting.

7. NEVER back up with the openers in the ground. If you do, check all openers to be sure none are plugged.

8. ALWAYS raise the openers at the end of field rows and other sharp turns.

MAINTENANCE AND LUBRICATION

PROPER SERVICING AND ADJUSTMENT IS THE KEY TO THE LONG LIFE OF ANY FARM IMPLEMENT. WITH
CAREFUL AND SYSTEMATIC INSPECTION, 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.

4. Disk scrapers should be kept properly adjusted.

9-1

2. Lubrication -- listed below are the items you need to lu­bricate every 8 - 10 hours of operation:

a. Each opener lift tube, half clamp.
b. Clutch assembly.

3. Lubrication -- listed below is the item you need to lubri­cate once a season:

a. End wheel hub bearings.

5. Always maintain the proper air pressure in the rib im­plement tires.

STORAGE

1. Clean the drill as necessary. BE SURE that the seed
box, fertilizer box and all feed systems are completely
cleaned before storing.

2. Oil and adjust all roller chains.

3. Feed cup drive sprocket hub should be oiled in its
square bore. Squirt oil on to the square feed cup shaft
and move feed cup adjustment lever back and forth in or­der to get the oil back into the square. This is most impor­tant before putting the drill in storage.

4. Lubricate all fittings as indicated in “Maintenance and
Lubrication” on page 21.

5. When in storage, lower the drill with openers on a
board or hard surface. Apply a light coat of oil to exposed

movement.
c. Check disk bearings.
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.
f. Check press wheel adjustment for seeding depth.

10-1

3. Actual seeding rate is different a. Check tire pressure. Proper inflation is listed on page 1-4
than desired in "Tire Inflation Chart".

b. Check tire size. Proper size is 7.50" x 20".
c. Seed treatment will affect seeding rate if the chemicals build up in

seed cup. Unless cleaned regularly, this build up can cause break-

age of the feed shaft.
d. Check sprocket drive type.
e. See Operator’s Manual for instructions on calculating seed

rate.

4. Excessive seed cracking a. Use slower drive type and open flutes in feed cup to a wider posi­tion.

b. Position feed cup handles to a lower notch.

5. Acremeter doesn’t measure a. Check tire pressure. Proper inflation is listed on page 1-4 in

accurately "Tire Inflation Chart".

b. Check tire size. Proper size is 7.50" x 20".
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, see page 5-1 on "Seeding Ad-

justments".

f. Check to be sure your acremeter is for your width of drill.

6. Uneven seeding depth a. See section on depth adjustments.

7. Press Wheel not compacting the a. Reset press wheel height, see seeding and press wheel

soil as desired adjustments sections.

b. 2" x 13" Double "V" press wheel angles may need to be adjusted.
c. Downpressureon disk openers is not enough(Refer to section on
