Model 2250 Air Drill Implement 160-192M

Great Plains Mfg., Inc.

Section 2 Operating Instructions

General Description

This unit is a tillage-type seeding implement that can be

used in both conventional and no-till seeding applications.

It is designed to be used in conjunction with and towed be-

hind a Great Plains air drill cart. The cart supplies pneu-

matically conveyed seed or fertilizer through ﬁve or ten

2 1/2” primary hoses. Each 2 1/2” hose is connected to a

distribution tower where the seed or fertilizer is evenly dis-

tributed and carried by air and gravity through a 1” second-

ary hose to each opener or coulter. The implement frame

accepts two types of openers: a ﬂoating hoe opener or a c-

shank-style opener. The openers, conﬁgured in a 7” row

spacing, can be mounted across four ranks 28” apart. The

openers can also be placed on a 7” row spacing across the

rear three ranks 28” apart thereby allowing the use of

coulters on the front rank. The coulters are placed so that

they run in between every two rows (14” apart). The

coulters are used to cut through residue and can be

equipped to apply dry fertilizer.

Seeding depth is controlled by front gauge wheel and

press wheel gang height. Coulter depth can be adjusted

individually.

The implement is equipped with an electric clutch switch to

stop and start metering at the cart when the implement is

raised and lowered. The switch is adjustable so that the

height at which metering is stopped or started can be varied.

Prestart Checklist:

• Lubricate the implement as indicated in the Lubrication

portion of the “Maintenance and Lubrication” section

starting on page 39.

• Check all tires for proper inflation. See the Tire Inflation

Chart in the “Appendix” section on page 44.

• Perform all beginning of season and daily service items

discussed in the “Maintenance and Lubrication” sec-

tion starting on page 39.

• Check the implement for worn or damaged parts and re-

pair or replace them before going to the field.

• All nuts, bolts, and screws should be checked. Refer to

the Torque Value Chart in the “Appendix” section on

page 44.

Recommended Tractor Size

Recommended Minimum Tractor Size

Standard openers and coulters - 240 HP

Double shoot openers - 300 HP

NOTE: The tractor must be of adequate size to pull

the drill. When determining size of the tractor, soil

type, terrain, opener type, and tillage practices must

be considered.

CAUTION!

The tractor or towing vehicle must have adequate unladen mass

to control the drill when towing. Do not exceed 20 miles per hour.

Minimum towing vehicle weight - loaded drill:

up to 20 mph maximum - 45,000 lbs.

up to 10 mph maximum - 22,000 lbs.

Minimum towing vehicle weight - empty drill:

up to 20 mph maximum - 28,000 lbs.

up to 10 mph maximum - 14,000 lbs.

Safety Lights

The light package your drill comes equipped with requires

that your tractor be wired for the standard 7-pin electrical

connector which will work with the tractor’s ﬂashers and

signals. The harness from the air drill cart should be ready

to plug into the connector.

If your tractor is not equipped with this connector, please

consult your dealer for installation to the tractor manufac-

turer’s speciﬁcations.

Field Operations

1. Be sure that all tires are properly inﬂated as indicated

in the Tire Inﬂation Chart in the “Appendix” section

on page 44.

2. Be sure that all hoses are connected and clear of for-

eign material. Make sure openers are not plugged.

3. Never back up with the openers in the ground. Do not

turn sharply with openers in the ground, doing so will

cause openers to plug and could cause damage to the

implement.

4. Make sure that nobody is in the way of the drill before

moving. Do not allow anyone to ride on the drill.

5. Follow all cart ﬁeld operation instructions as found in

the cart operator’s manual.

6. With a properly adjusted implement height switch, it is

not necessary to turn the electric clutch switch on and

off manually while turning. The clutch switch should

be turned off while transporting.

7. Be aware of a slight 5' to 10' delay needed for the seed

to reach the openers when starting to move forward. If

you stop in the middle of the ﬁeld, lift the drill and back

up 10' and then proceed from that point.

8. Always operate farm machinery with safety in mind.

NOTE: The tractor must have at least three sets of

hydraulic outlets and be capable of supplying 15-30

gallons per minute at 2000 psi.
