Model 2250 Air Drill Implement 160-192M

Great Plains Mfg., Inc.

8. Do not remove cylinder lock channels from a folded

implement.

Unfolding the Drill

DANGER!

Overhead crushing hazard. To prevent serious injury or death:

● Always use cylinder lock channels when folding or unfolding

implement.

● Fold or unfold implement only if fold cylinders and hoses are

bled free of air and are fully charged with hydraulic oil.

● Stay away from frame sections when they are being folded,

unfolded, or are in the folded position.

● Keep bystanders well away from the implement.

DANGER!

Electrocution hazard -

To prevent serious injury or death from electrocution: Keep

clear of overhead power lines when transporting, folding, un-

folding, or operating all air drill components. Machine is not

grounded. Electrocution can occur without direct contact

1. Unfolding the drill is to be done on level ground only.

Be aware of the clearance required to unfold the drill.

Do not unfold the drill where it may come into contact

with any obstructions or overhead lines. Keep all by-

standers clear away from the area.

2. Remove folding lock pins and place them in the stor-

age rings.

3. Set tractor at low idle speed.

4. Slowly unfold the implement. During unfolding, one in-

ner-frame section will unfold to approximately a 45 de-

gree angle and stop. The outer frame section will then

fold out straight. Both frame sections will then unfold

until the outside gauge wheels support the two frame

sections. When one side has completely unfolded, re-

lease and momentarily reverse the hydraulic lever.

This will shift the spool in the sequencing valve so that

the other wing will unfold when the hydraulic lever is

again moved to unfold.

5. When the sections are unfolded, hold the lever until

the cylinders are completely extended to ensure that

wing ﬂexibility will not be limited.

Opener Operation

General Opener Operation

1. Never back up or turn sharply with openers in the

ground. Doing so will plug openers and may result in

equipment damage.

2. Check periodically for plugged openers and hoses.

With the fan running, manually operate the metering

system. Look below each opener for seed or fertilizer.

Do not crawl among the openers unless cylinder lock

channels are installed, the implement is sufﬁciently

blocked up, and the tractor is shut off with the key re-

moved.

For information on setting seed depth and making opener

adjustments, see Setting Seeding Depth and Leveling

Front-to-Rear in the “Adjustments” section on page 33.

C-Shank Style Opener

The C-shank style opener is designed to accept many dif-

ferent hoe openers. The C-shank opener should provide

about 350 pounds of resistance at the hoe tip in the ﬁrst

inch of travel. If the opener encounters an immovable ob-

ject, the shank will trip back in order to travel over the ob-

ject after which it will spring back to its normal operating

position.

DANGER!

The C-shank opener comes equipped with a pre-compressed

spring. Any attempt to remove or adjust the spring could release

the spring’s stored energy and could result in serious injury or

death.

Floating Hoe Opener

The ﬂoating hoe openers (shear bolt and spring reset)

both have an ability to “give” when they encounter obstruc-

tions. The spring reset hoe will trip when a large obstacle

is encountered. If the opener does not fully return to its

original position, lift the drill out of the ground and allow the

spring to pull the opener back down.

For shear bolt openers, you must replace broken shear

bolts to reset the openers. Use 5/16” x 3” grade 5 bolts

only (Great Plains part number 802-131C).

Transporting

CAUTION!

This implement should never be towed faster than 20 miles per

hour.

Before transporting the implement, check and practice the

following items.

• When hitched to an air drill cart, the combined weight of

this implement and cart must always be kept in mind. Be

sure that sufficient stopping distance is allowed at all

times and speed is reduced prior to making any turns or

other maneuvers.

• Be sure that the towing vehicle is large enough to control

the drill and implement on the road. Refer to Tractor Re-

quirements, this section, on page 29.

• Know the maximum dimensions of the cart and imple-

ment in transport position and follow a route that pro-

vides adequate clearance from all obstructions. Be

especially observant of low overhead power lines.

• Be sure that all cylinder lock channels and transport lock

pins are in place.
