Section 3 Adjustments

Model 2250 Air Drill Implement 160-192M

5/11/05

Great Plains Mfg., Inc.

The front to back setting of the fertilizer tine can be
changed by loosening the two 5/8” carriage bolts (#1) that
hold the fertilizer tine arm (#2) to the main coulter arm
(#3). With the carriage bolts loose, the fertilizer tine arm
can be slid up and down the coulter arm. This will change
the distance from the rear of the coulter blade to the fertil-
izer tine (#4) and it will also change the fertilizer tine depth
(the tine should be approximate 1” from the rear of the
coulter blade). Keep in mind that the fertilizer tine should
remain in a vertical or slightly swept back position. A slot-
ted hole (#5) in the fertilizer tine arm can be used to keep
the tine in proper orientation.

Once the horizontal distance from the coulter blade to the
fertilizer tine is set, the vertical position should be adjusted
so that the tip of the tine will operate approximately 1” to 1
1/2” below the surface of the soil. This adjustment can be
made by removing the 1/2” bolt (#6) and spring tine clip
(#7) and moving the spring tine attachment to a higher or
lower hole. Again, the slotted hole in the fertilizer tine arm
can be used to help make this adjustment.

Electric Clutch Height Switch

WARNING!

Do not place any part of body under implement while making
adjustments.

Locate the height switch. The height switch can be
found on the right hand front dual gauge wheel rock-
shaft.

Lower the implement until it is at a height where seed-
ing should start (usually just above the ground).

Turn off the tractor and remove the key.

Refer to Figure 3-10. Loosen the cam clamp (#1) on
the rockshaft and turn until the switch roller (#2) is just
starting to make contact with the ramp surface.

NOTE: The switch circuit is designed so that seed will
be metered if the switch is extended (off cam). Meter-
ing is stopped when the switch is compressed (on
cam). Meter will not shut off when the implement is
raised if cam clamp should come loose.
