Introduction
Introduction
Great Plains welcomes you to its growing family of new
product owners. This implement has been designed with
care and built by skilled workers using quality materials.
Proper assembly, maintenance and safe operation will
help you get years of satisfactory machine use from your
machine.
Description of Unit
The NTA3010 and NTA3510, serial numbers Z1370 and
lower (“Z1370-”) are seeding implements designed to tow
behind a Great Plains ADC1150 or ADC2220 Air Drill
Cart. For drills serial numbered Z1371+, see Operator
Manual 160-219M-A.
Working width is 30 or 35 feet. The implements are designed for no-till field conditions. Coulters open a narrow
seedbed. Disk-type, parallel-linkage openers follow each
coulter, widening the seedbed and delivering seed to the
trench.
The cart uses air to move seed through primary seed hoses to distribution towers on the implement. From the towers, seed is blown through secondary seed hoses to each
opener. The openers are equipped with press wheels,
which then firm the seedbed.
The implement is equipped with two hydraulic circuits. The
lift hydraulics raise the implement for field turns and folding. The fold hydraulics raise the wing sections for transport. The fold hydraulics also power the cart fan and
transfer weight from the implement center section to the
wings during seeding.
Intended Usage
Use this machine for seeding small grains and legumes in
no-till or minimum-till applications.

This section covers implement preparation and setup. Before using the implement in the field, you must hitch the implement to your tractor, check that the hydraulics have
been bled of air, and check that the implement frame is level.
Hitching Cart to Implement
!
WARNING!
You may be severely injured or killed by being crushed between
the cart and implement. Always park and shut off the tractor before placing any body part between the cart and implement.
Refer to Figure 1-1.
1. Remove the pivot pins (1) from the lugs (2) on the center section of the implement frame.
2. With cart links tied up, slowly back cart toward the
center of the implement.
3. When ball swivels (3) are aligned with implement lugs,
drive pivot pins back in place. Secure with roll pins.
4. Connect the primary seed hoses to the cart meter
box. Connect the hoses left to right in the same order
towers are installed on the implement. Leave enough
slack in hoses so the drill can be fully raised, lowered,
folded and unfolded. Secure hoses to meter-box outlet
tubes using the 2 1/2-inch band clamps provided. Be
sure outer clamps do not interfere with meter-box door
latches. Refer to Figure 1-2.

Hydraulic Hose Hookup
!
WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs, see
a doctor immediately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene will result.

NOTE: SAE O-ring and JIC 37˚ flare-type hose connections do not require sealant or high torque for a good seal.
Carefully check all hoses to make sure none will be damaged by implement operation. Reroute hoses or use cable
ties to keep hoses in a safe place.
Bleed the Hydraulics
To function properly, the hydraulics must be free of air. If
the hydraulics have not been bled, the implement will fold
in jerky, uneven motions or some frame sections will run
higher than others. If the hydraulics were not bled during
initial implement setup or if you replace a part in the hydraulic system during the life of the drill, complete the following procedures.

WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs, see
a doctor immediately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene will result.
Bleeding Lift Hydraulics
The lift system is equipped with rephasing hydraulic cylinders that require a special procedure for bleeding air from
the system. Read and follow the procedure carefully.
!
WARNING!
You may be severely injured or killed by being crushed from a
falling implement. Always have transport locks in place and
frame sufficiently blocked up when working on implement.
1. Check hydraulic fluid level in tractor reservoir and fill to
proper level. Add fluid to system as needed while cycling new cylinders. You will need about 8 3/4 gallons
of oil to fill new cylinders.
2. Support implement frame sections with jack stands or
blocks.
3. With frame blocked and supported, unpin rod ends of
wheel cylinders. Pivot cylinders up and wire or otherwise safely support rod ends higher than base ends
as shown in Figure 1-6. You may need to remove the
gauge-wheel cylinders from the rockshaft so you can
orient them with rod ends higher than base ends.

!
WARNING!
Before attempting to hydraulically lift the implement, the cart
must be attached to the implement and a tractor of sufficient
size. Failure to do so could result in severe equipment damage
and bodily injury or death.
1. Check the hydraulic fluid level in the tractor reservoir
and fill to the proper level. You will need about 6 gallons of oil to fill new cylinders.
2. Be sure implement is hitched to cart and tractor. See
Hitching Cart to Implement, page 10.
3. Hydraulically raise the implement and install rockshaft
and lift-assist transport locks. Refer to Lifting the Im-
plement,“Field Operations,” page 15.
4. Unpin rod end of fold cylinders. Block, wire or otherwise safely support the rod ends as shown in Figure 17 so they will not contact anything when extended.

Section 1 Preparation and Setup
Level Frame Side to Side
All frame sections must be level to maintain even seeding
depth. Before using the implement in the field, follow these
steps to make sure the implement is level side-to-side.
Periodic frame-leveling adjustments should not be necessary, but if you are having problems with uneven depth,
check drill levelness and follow these procedures.
1. Check that the lift hydraulics are free of air and full of
oil. See Bleeding the Lift Hydraulics, page 12.
2. Unfold and lower the implement. Make sure the lift cylinders are fully retracted, then block up or otherwise
support the frame.
3. Take a reference measurement by laying a straight
edge across the top of the two coulter mount tubes on
the center section. Measure from the bottom of the
straight edge to the center of one rockshaft-wheel axle
as shown in Figure 1-8. Because rockshaft gauge
wheels are not adjustable, all adjustments will be
made relative to this measurement.
5. If the wing measurement differs from the reference
measurement, remove the pin from the rod end of the
wing-gauge-wheel cylinder. Block or support the wing
gauge wheels so the distance from the bottom of the
straight edge to the center of the wing-gauge-wheel
axle is the same as the reference measurement taken
in step 3.
6. Loosen the nuts (1) on the cylinder eye bolt as shown
in Figure 1-10. Move the eye bolt in or out until the rod
end of the cylinder can be pinned to its lug. Secure the
eye bolt by tightening the nuts.

4. Move the straight edge to one of the wings. Measure
the distance from the bottom of the straight edge to
the center of wing-gauge-wheel axle as shown in Figure 1-9.
7. Repeat steps 4, 5 and 6 for other wing section.
Level Frame Front to Rear
The front-to-rear levelness of your drill will also affect
seeding depth. If the lift-assist wheels raise the rear of the
implement higher relative to the front, the openers may operate at the wrong angle. The opener bodies should run
parallel to the ground. If they do not, level the angle which
the implement runs by following these instructions.
1. Check that the lift hydraulics are bled of air and full of
oil. See Bleeding the Lift Hydraulics, page 12.
2. Turn the nuts (1) on the eye bolt on the lift-assist cylinder shown in Figure 1-11.
• To raise rear of implement, move eye bolt in toward
drill.
• To lower rear of implement, move eye bolt out.
3. Repeat for other lift-assist wheel.

Section 2 Operating Instructions
Great Plains Mfg., Inc.
This section covers general operating procedures. Experience, machine familiarity and the following information will
lead to efficient operation and good working habits. Carefully read the operator’s manual for the air drill cart you will
be using with the implement. Always operate farm machinery with safety in mind.
General Description
The implement has two hydraulic circuits. One circuit lifts
the implement. A second powers the cart fan, implement
folding and weight transfer.
An electric circuit powers a clutch on the cart metering
system and a solenoid valve on the implement weighttransfer system. The circuit has a master switch in the
tractor cab that powers the entire circuit. An automatic
switch on the implement rockshaft engages and disengages the clutch as the implement is lowered and raised. The
in-cab switch must be on during field use and off during
folding, unfolding and transport.
!
WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs, see
a doctor immediately. Any fluid injected into the skin must be
surgically removed within a few hours or gangrene will result.
Rephasing Lift System
Over 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 hydraulic remote lever on for several seconds until all cylinders are fully extended. Do this every time you raise
the implement out of the ground.
2. When all cylinders are fully extended, momentarily reverse the hydraulic remote lever to retract the system
1/2 inch to maintain levelness.
Lift System Transport Locks
The lift system has transport locks for the rockshaft and
lift-assist cylinders. Use these locks every time you raise
the drill for maintenance, lubrication, folding or transport.
To install the rockshaft locks, remove the locks from storage on the implement frame. Pin the locks in place on the
raised implement as shown in Figure 2-1.
Pre-start Checklist
1. Lubricate the implement as indicated under Lubrication,“Maintenance and Lubrication,” page 28.
2. Check all tires for proper inflation as indicated on Tire
Inflation Chart,“Appendix,” page 33.
3. Perform all beginning-of-season and daily service
items under General Maintenance,“Maintenance
and Lubrication,” page 28.
4. Check the implement for worn or damaged parts. Repair or replace them before going to the field.
5. Check all nuts, bolts and screws. Refer to Torque Val-
ues Chart,“Appendix,” page 33.
Lifting Implement
Your air drill implement is equipped with rephasing hydraulic cylinders in a master-slave configuration. For proper
operation the system must be free of air. Refer to Bleed
Hydraulics,“Preparation and Setup,” page 11.

always use transport locks when folding or unfolding implement.
• Always use transport locks when implement is folded.
• Fold implement only if fold hydraulics are bled free of air and
fully charged with hydraulic oil.
• Stay away from frame sections when they are being raised or
lowered or are in the raised position.
• Keep away and keep others away when folding or unfolding
implement.
!
DANGER!
Electrocution hazard. To prevent serious injury or death from
electrocution, keep clear of overhead power lines when transporting, folding, unfolding or operating all air drill components. Your machine is not grounded. Electrocution can occur
without direct contact.
1. Park implement on level ground. Be aware of clear-
ance required to unfold implement.
2. Remove wing fold pins.
3. Check that hydraulic selector valve is in fold/unfold po-
sition.
4. Check that in-cab rocker switch is off.
5. Set tractor at low idle speed.
6. Energize tractor hydraulics for fold system and slowly
unfold implement.
7. Continue to unfold implement only until each wing
gauge wheel rests on ground.
8. When sections are unfolded, immediately turn selec-
tor valve to field position as shown in Figure 2-9.
Field Operations
To operate the seed-metering and weight-transfer systems, the in-cab rocker switch must be on. A height switch
on the implement rockshaft will automatically turn seed
metering and weight transfer off and on as you raise and
lower the drill for field turns.
!
WARNING!
Operate implement only when hitched to a Great Plains air drill
cart. Modifying the implement for use with other machines
could lead to field or road accidents, serious injury or death.
For normal seeding operations:
1. Check that the in-cab rocker switch is on.
2. Turn the hydraulic selector valve to the Field position
as shown in Figure 2-9.
3. Energize tractor hydraulics for fan. Lock hydraulic lever in place for continuous operation.
4. Run fan for at least 15 minutes before seeding. Hydraulic fluid must be warm before fan and wing down
pressure will operate properly.
5. Watch the monitor and adjust fan speed by increasing
or decreasing hydraulic flow from the tractor. Use the
following guidelines and the fan speed chart to properly adjust fan speed.
• Higher fan speeds improve seed distribution, but high
fan speeds also increase the chance of seed damage
and bounce.
• At first, adjust fan speed to the high end of the range
suggested in the fan speed chart. Watch for excessive
seed cracking and seed bounce from the furrow, then
reduce fan speed if necessary.
• Follow the chart below as a guide. Actual fan speeds
will vary with seeding rates, seed weights and seed
size. Increase fan speed for heavier seeding rates or
seed. Reduce fan speed for lighter seeding rates and
seed more prone to cracking.

7. When finished seeding, turn the in-cab switch off and
the selector valve to Fold/Unfold before transporting.
Opener Operation
• Raise implement before turning. Never back up or turn
sharply with openers in the ground. Doing so will plug
openers and may damage equipment.
• Be aware of a 5- 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.
!
WARNING!
Crushing hazard. You could be seriously injured or killed if the
raised implement falls. 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.
• Check periodically for plugged openers and hoses. With
the fan running and the drill raised, hand crank the metering system. Look below each opener for seed or fertilizer.
• For information on opener adjustments, see Opener Ad-
justment,“Adjustments,” page 22, and Level Frame
Front to Rear,“Preparation and Setup,” page 13. For
more information on troubleshooting opener problems,
see “Troubleshooting,” page 25.
Marker Operation
If you have purchased markers, the following will help you
integrate the markers with the air drill hydraulic system.
Carefully read the marker manufacturer’s instructions for
safe installation, operation and adjustment.
Marker attachments are controlled by the same hydraulic
circuit as the cart auger. To operate the markers, move the
hydraulic diverter valve on the cart tongue up to the marker position as shown in Figure 2-10.

dimensions.
Transporting
!
DANGER!
Electrocution hazard. To prevent serious injury or death from
electric shock, keep clear of overhead power lines when transporting, folding, unfolding or operating all air drill components. 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 fullyloaded, 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.
Hitching the implement to any vehicle other than a Great Plains
air drill cart will create an unstable towing load and can lead
to road accidents, injury and death. To avoid the hazard, transport the implement only when hitched to an Great Plains air
drill cart.
Before transporting the implement, check and practice the
following items.
Minimum Towing Vehicle Weight
Hitched to ADC2220: 25,550 pounds

Seeding Depth
To correctly adjust seeding depth, you need a good understanding of how the coulters, openers and press wheels
work. The following is an introduction to how the no-till
coulter and double-disk openers are designed to control
planting depth.
Coulters
A no-till coulter is mounted independent and directly
ahead of each opener. Each coulter cuts through heavy
trash to make a groove in the soil for the openers. The
coulters are mounted on the frame, so coulter cutting
depth changes as the drill is raised and lowered. Coulter
down force can be changed by adjusting coulter spring
length, adding weights, moving the hydraulic depth stop,
or changing the height of individual coulter mounts. Refer
to Coulter Adjustments, this page, for information on how
to make these adjustments.
Openers
The openers are mounted on the implement frame with
parallel links. This allows the opener arms to move up and
down while keeping the openers in-line with the coulters.
This parallel-action mounting also maintains the contact
point throughout the opener’s depth range. Opener double
disks widen the coulter groove to make a seed bed. A seed
tube mounted between the disks delivers seed to the
trench. The down force needed by each opener to cut and
widen the coulter groove is supplied by two springs nested
in the parallel linkage. Adjusting these springs changes
opener down-force. Refer to Opener Adjustment, page 22,
for information on how to make this adjustment. When
making seeding depth adjustments, keep in mind that
openers will not run any deeper than coulters till the soil.
Press Wheels
Attached to the rear of each opener is one of several optional press wheels. The press wheel provides two important functions.
First, the press wheels close the furrow, gently pressing
the soil over the seed. To provide consistent seed firming,
the press wheels are free to move downward from the normal operating position. This system maintains pressing
action even if the opener arm is lifted when the disks encounter obstructions.
Second, the press wheels provide opener depth control.
The higher the press wheels run relative to the double
disks, the deeper seed will be placed. To maintain a consistent depth, upward press wheel movement is restricted
by an independently adjustable stop on each opener. Refer to Press Wheel Adjustment, page 21, for information on
how to make this adjustment.
Coulter Adjustments
The air drill is factory assembled so that when the coulters
are set to run 2 inches deep, the seeding depth is approximately 1 inch. This is a good baseline setting for most
seeding conditions. You have the option of changing settings on the entire implement or individual coulters as field
conditions warrant.
!
WARNING!
Crushing hazard. You may be severely injured or killed if the implement falls on or runs over you during maintenance. Always
turn off tractor and remove the key before making any adjustments or performing maintenance. Securely block and install
transport locks on raised implement before working under or
around it.
Hydraulic Depth Control
The lift cylinders on the implement control coulter depth. A
valve in the hydraulic line on the left-wing, gauge-wheel
cylinder regulates depth. Figure 3-1 shows the valve and
knob used to adjust coulter depth.
Raise Coulters
Lower Coulters

Turn the knob clockwise to lower the coulters. Each clockwise rotation will lower the coulters about 3/16 inch. Make
depth adjustments withthe implement slightly raised.After
adjusting the valve, raise and lower the implement several
times and recheck coulter depth.

Section 3 Adjustments
Coulter Springs
Coulter springs are preset at 10 inches, giving the coulters
an initial operating force of 400 pounds. This setting is adequate for many difficult no-till conditions. For lighter no-till
conditions where rocks or other obstructions are a problem, you can lengthen the springs to protect the coulters
from impact. Refer to the chart below for spring length and
corresponding coulter down force.
Spring Length Coulter Down Force
10 1/4 in 300 lb
10 in 400 lb
9 3/4 in 525 lb
NOTE: Any attempt to reset the coulter spring length
shorter than 9 3/4 inches may contribute to premature failure of parts and warranty shall be voided. If additional
force is needed, add weights to the implement.
Weights
!
WARNING!
Crushing hazard. Weights that are not properly secured or positioned could fall off the implement during folding, field operation or transport and cause severe injury or death to
bystanders. Adding weight to the wings could cause a wing to
drop suddenly during folding and severely injure or kill bystanders. Do not add more than eight weights (four pairs) to the
implement. Use only Great Plains weights, part number 163233A, as additional weight on the implement. Do not add
weights to the wing sections.
Many no-till conditions will require additional weight for
sufficient coulter depth. Additional weights are available
from your Great Plains dealer. Up to eight 700-pound
weights can be evenly distributed over the center section
of the implement. Refer to the weight chart below to see
the results of adding weights.
Individual Coulters
Individual coulters that run in tire tracks can be lowered if
desired. To raise or lower individual coulters:
1. Loosen the mounting clamps and adjust the coulter to
the desired height.
2. To retighten clamps, refer to Figure 3-2. Snug the hexhead clamp bolts (1) just until the u-bolts are tight on
each side of the spring bar.
3. Tighten nuts (2) on u-bolts.
4. Finish tightening hex-head clamp bolts.
10300
Figure 3-2
Individual Coulter Mounting
NOTE: Ground clearance on lowered coulters will be reduced when the implement is in the raised position.
Press Wheel Adjustment
To change the height of the press wheel, lift and slide the
“T” handle on top of the opener arm as shown in the Figure
3-3.
• To lower the press wheel for a more shallow seeding,
slide the handle toward the implement.
• To raise the press wheel for deeper seeding, slide the
handle away from the implement.

Wing Down Pressure Adjustment
The implement isequipped with weight-transfer hydraulics
to evenly distribute weight between the frame sections.
While seeding, hydraulic down pressure is placed on the
wings so all frame sections run at the same depth. If there
is not enough weight on the wings, they will run higher
than the center section.
To adjust wing down pressure,
1. Check that in-cab rocker switch is on and selector
valve is turned to field position. Refer to Figure 2-9,
page 17.
2. Lower implement so openers are on ground.
3. Engage fan hydraulics.
4. Turn pressure-control valve shown in Figure 3-4.
When facing valve,
• increase weight on wing sections by turning clock-
wise.
• decrease weight on wings by turning counterclock-
wise.
Typical pressures on gauge shown in Figure 3-4
should be 200 to 600 psi.
IMPORTANT: Do not exceed 800 psi. Exceeding 800
psi could cause equipment damage.
Opener Adjustment
Seed cannot be placed any deeper than coulter cutting
depth. Before adjusting openers, check that coulters are
running deep enough and that the frame is level from front
to rear. Refer to Coulter Adjustments, page 20, and Level
Frame Front to Rear, “Preparation and Setup,” page 13.
Adjust the parallel-linkage openers with the tool stored on
the rear tube of the center frame section.
To increase or decrease opener down-force, position the
tool in the holes on the left and right mounting plates
shown in Figure 3-5 and pull down on the adjuster. This
will reposition the springs and change opener down force.

Disk Scraper Adjustment
To keep the opener disks turning freely, dirt scrapers are
mounted between the disks to clean as the disks rotate.
As field conditions vary, the scrapers may need to be adjusted. In damp conditions, the scrapers may need to be
lowered. If openers are not turning freely, the scrapers
may need to be raised. To adjust the scrapers, loosen the
3/8-inch bolt as shown in Figure 3-10 and move scraper as
needed.

Harrow Adjustment
Figure 3-11 shows a successful harrow position for no-till
conditions. Because of different soil moisture, trash levels
and trash types, you may need to reposition the tube
frame or tines. Initially position the frame and tines as
shown in Figure 3-11, then re-adjust as necessary.

Figure 3-11
Tine Angle For No-Till Drilling
To adjust the frame, refer to Figure 3-12. Loosen the four
hex nuts (1) on the u-bolts and rotate the frame tube (2) as
necessary.
To adjust the tines, refer to Figure 3-12. Loosen the four
1/2-inch hex nuts (3) on the 1/2-inch u-bolts (4) on the support bar (5). Rotate tine tubes (6) so the tines (7) are
against the stop bushings (8) and are angled back as necessary. Retighten hex nuts on u-bolts.
Seed-Lok
The optional Seed-Lok firming wheels provide additional
seed-to-soil contact. The wheels are spring loaded and do
not require adjusting. In some wet and sticky conditions
the wheels may accumulate soil.
To lock up the firming wheels, hook one end of the chain in
the opener-body hole just above the wheel arm (1). Pull
the firming- wheel arm (2) up as high as possible and wrap
the chain around the arm. Hook the other end of the chain
in a link. Leave no slack in the chain; secure the wheel arm
in its highest position

Section 5 Maintenance and Lubrication
Great Plains Mfg., Inc.
General Maintenance
Proper servicing and adjustment is the key to the long life
of any farm implement. With systematic inspection and lubrication, you can avoid many costly repairs and downtime.
Always turn off and remove the tractor key before making
any adjustments or performing maintenance.
!
WARNING!
You may be severely injured or killed by being crushed from a
falling implement. Always have transport locks in place and
frame sufficiently blocked up when working on implement.
!
WARNING!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Check all hydraulic lines and fittings before
applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, and
wear heavy gloves 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.
!
CAUTION!
Disk edges and harrow tine teeth are very sharp. You may injure
yourself. Use caution when working in this area.
1. After initially running the implement for several hours,
check all bolts to be sure they are tightened as specified on the Torque Values Chart,“Appendix,” page
33. Do not over tighten the bolts holding the distribution tower assembly together.
2. Lubricate the implement as noted under Lubrication,
this page.
3. Always maintain correct pressure in tires. See Tire In-
flation Chart,“Appendix,” page 33.
4. Replace any worn, damaged or illegible safety labels
at once. Refer to Safety Labels,“Important Safely In-
formation,” page 4, for correct label placement. Obtain new labels from your Great Plains dealer.
5. Clean or replace any fittings that will not take grease.
6. Periodically check and secure all bolts, pins, and fasteners. Tighten as specified on the Torque Values
Chart,“Appendix,” page 33.
7. Occasionally inspect hydraulic hoses for cuts, cracks
and aging. Check fittings and cylinders for evidence of
leaks.
8. Inspect cart link pins often for wear or loosening.
Storage
Store the drill in an area where children do not play. Store
the implement inside if possible for longer implement life.
1. If you store the drill in the unfolded position, unpin the
rod ends of the fold cylinders and retract cylinders fully
to prevent rust.
2. If the cart is disconnected from the implement for storage, plug all 2 1/2-inch openings to prevent birds from
nesting in them.
3. Lubricate the drill at all points indicated under Lubrica-
tion, this page.
4. Check all bolts, pins, fitting and hoses. Tighten, repair
or replace parts as needed.
5. Check all moving and soil-contact parts for wear or
damage. Make notes of any parts needing repair before the next drilling season.
6. Use Great Plains touch-up paint to cover scratches,
chips and worn areas to prevent rust.
