LS10 and LS12 Table of Contents Index Safety Information
High Pressure Fluids
1. Escaping fluid from holes in hydraulic lines is difficult
to spot. Do not use your hands or bare skin to search
for suspected leaks; instead, use a piece of
cardboard or wood. If injured by escaping hydraulic
fluid, see a medical professional immediately.
Exposure can result in gangrene or severe allergic
reaction.
2. Check that hydraulic fittings are tight and all hydraulic
hoses and lines are in good condition before
applying pressure to the system.
3. Wear protective gloves and safety glasses or
goggles when working with hydraulic systems.
Transporting
1. As with transporting any piece of heavy machinery,
comply with all local laws and regulations before and
during transport process.
2. Transport only at recommended transport speed for
implement. Some rough terrains require a slower
speed. Sudden braking can cause a towed load to
swerve and upset.
3. Before towing implement on roads, make sure to
empty out all material from the hoppers or boxes.
4. Know transport height and width of implement.
5. Do not tow an implement that, when fully loaded,
weighs more than 1.5 times the weight of towing
vehicle.
6. Keep clear of overhead power lines and other
obstructions when transporting.
7. Reduce speed when turning, and make as wide a
turn as possible. Turning tractor too tight can cause
implement to tip over.
8. When towing on a trailer, secure implement with tie
downs and chains.
9. When towing on a trailer, sudden braking can cause
a trailer to swerve and upset. Reduce speed if trailer
is not equipped with brakes.
Safety Chain
1. Use a chain with a strength rating equal to or greater
than the gross weight of towed machinery.
2. Replace chain if any links or end fittings are broken,
stretched or damaged.
3. Do not use safety chain for towing.
Safety Lights and Devices
1. Always use safety lighting. Slow-moving tractors and
towed machinery can create a hazard when driven
on public roads. They are difficult to see, especially
at night.
2. If equipped, use flashing warning lights and turn
signals whenever driving on public roads.
3. Use safety devices provided with implement.
4. Keep safety lights and signs clean and visible from
front and rear of machine.
5. Keep lights in operating condition.
Shutdown and Storage
1. Park the tractor and implement on a solid, level
surface where children normally do not play.
2. Put tractor in park or set the parking brake. Turn off
engine and remove switch key to prevent
unauthorized starting.
3. Wait for all components to come to a complete stop
before leaving the operator’s seat.
4. Detach the tractor. Secure the implement using
blocks.
Proper Waste Disposal
1. Dispose of waste properly to avoid threatening the
environment and ecology. Potential harmful waste
includes oil, fuel, filters, and batteries.
2. Use a leak-proof container for draining fluids. Do not
use a food or beverage container that may be
mistaken for a consumable product.
3. Do not drain or pour waste onto the ground, down a
drain, or into any water source.
4. Contact your local environmental or recycling center
for the proper way to recycle or dispose of waste.

Seeding Rate Adjustment
To calibrate the seeding rate, the seeder and plow must
be hooked to the tractor that will be used in the field and
the hydraulic drive must be hooked to the tractor
remotes.
Calibrate the seeding rate with a full box of seed.
1. Find your desired seeding rate and ground speed on
the seeding rate chart, page 14. Determine how
many shaft rpms are needed for your seeding rate
and ground speed.
2. With the tractor parked and idling in neutral, adjust
the tractor throttle up to field rpm.
3. Engage the hydraulic drive. Count the number of
seed-cup-shaft revolutions per minute by using a
tachometer.
4. Stop the hydraulic drive.
5. If the shaft is turning too slowly or quickly, loosen the
black knob (1)and adjust flow control on the hydraulic
drive.
6. Use the lever (2) to change rpms.
a. Move down to increase rpms.
b. Move up to reduce rpms.
7. When satisfied with the flow-control setting, lock the
black knob.
Seed Cup Doors
For rice and other small grains, move the seed-cup-door
handles to the highest position.
For larger seeds, lower the handles to the second or third
position to reduce seed cracking.
For seed-cup clean out, move the handles to the fourth,
wide-open position.

Distribution Panels
Seed is metered onto one of three distribution panels.
The panels distribute seed behind the levee plow. The
angle of these panels are adjustable.
To adjust the distribution panels:
1. Loosen the bolts in the rear panel slots.
2. Adjust the panel to the desired position and tighten
the bolts.

Troubleshooting
Problem Solution
Actual metering rate is different
than desired
Excessive seed cracking
Drill box not emptying evenly
Check seed-rate chart for proper seed-cup-shaft rpms for your seeding rate.
Refer to “Seeding Rate Chart” on page 14.
Adjust flow control on hydraulic drive. Refer to “Seeding Rate Adjustment”
on page 13.
Calibrate flow to hydraulic drive when seeder box is full of seed.
Refer to “Seeding Rate Adjustment” on page 13.
Check that seed-cup shaft is rotating is in the correct direction. If not, reverse
direction of flow to hydraulic drive by switching hoses at tractor outlets. Refer
to “Hydraulic Hose Connections” on page 9.
Position seed-cup handles to a lower notch. Refer to “Seed Cup Doors” on
page 13.
Check that seed-cup shaft is rotating in the correct direction. If not, reverse
direction of flow to hydraulic drive by switching hoses at tractor outlets. Refer
to “Hydraulic Hose Connections” on page 9.
Certain models do not have the same number of cups between each divider
of bulkhead. The section with more cups will empty sooner.

Maintenance and Lubrication
Maintenance
Proper servicing and maintenance is the key to long
implement life. With careful and systematic inspection,
you can avoid costly maintenance, downtime and repair.
Always turn off and remove tractor key before making any
adjustments or performing any maintenance.
Crushing Hazard:
You may be severely injured or killed by being crushed under
the falling implement. Always lower plow to the ground before
servicing the implement.
High Pressure Fluid Hazard:
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 immediate medical assistance from a doctor that is
familiar with this type of injury.
1. After using the seeder for several hours, check all
bolts to be sure they are tight.
2. Adjust the idlers to remove excess slack from the
drive chain.
3. Lubricate areas listed under “Lubrication” on
page 16.
4. Clean the seeder on a regular basis. Regular and
thorough cleaning lengthen equipment life and
reduce maintenance and repair.
5. Inspect hydraulic hoses for cuts, cracks, and aging.
Check fittings for evidence of leaks.
6. Replace any worn, damaged, or illegible safety
decals. Order new decals from your Great Plains
dealer. Refer to “Safety Decals” on page 4.

Storage
Always park implement with plow wings swept back and rear
parking stand in the parking position for maximum stability.
Do not use ladder or walkboard when unit is not hitched to
tractor.
Store seeder where children do not play. If possible, store
implement inside for longer life.
1. Clean seeder as necessary. Be sure the seed box is
cleaned completely before storing.
2. Lubricate as indicated under “Lubrication” on
page 16.
Removing Seeder from Plow
Crushing hazard:
You will be severely injured or killed if the seeder falls on you.
Secure seeder to lifting equipment so seeder cannot fall. Do
not walk or place any part of your body under the seeder as
the seeder is being lifted.
Obey all safety instructions from lifting equipment
manufacturer. Be sure lifting equipment has enough capacity
to lift seeder.
1. Reposition the ladders for use as stands. Remove
the ladders from the side of the seeder. Install the
ladders to the seeder through the lower set of holes
in the ladder.
2. Secure the seeder to the forklift or hoist.
3. Disassemble the flat bars (A) that secure the seeder
to the plow frame.
4. Lift the seeder off the plow.
