Native Grass Attachment
The Native Grass box is for seeding fluffy, native grass
blends like Big Blue Stem, Indian Grass, and Oats
Grama.
To adjust seeding rate:
1. Find the desired pounds per acre on the Native
Grass Rate Chart.
Refer to Figure 6
2. Determine which sprocket is required for the native
grass box. The sprockets are stored on the right
hand side of the drill frame.
To change sprockets, loosen the chain idlers
and remove chain.
Replace current sprocket with desired sprocket.
Refer to Figure 7
Move gearbox selector handle to desired drive type.
Checking Seed Rate
1. Record weight of an empty container large enough
to hold seed metered for one acre.
2. Fill three or more compartments at least 1/2 full of
seed at the outboard end of the box. Pull seed
tubes off the openers under the compartments.
Note: For drills built after October 1, 2005,
calibrate using right hand gauge wheel
or supplied calibration crank.
For drills built before October 1, 2005,
calibrate using right hand gauge wheel
or order the calibration crank kit available
through your Great Plains Dealer.
Note: If ordering the calibration crank kit, it is neces-
sary to order a second calibration coupler for na-
tive grass units. Extra calibration couplers are
available for order through your Great Plains
Dealer.
3. To calibrate using right hand gauge wheel, lower
the drill hydraulically to planting position in order to
activate clutch. Raise the right drive wheel tire off
the ground using a jack. Engage the gauge wheel
lockout on the right-hand side.
4. To calibrate using calibration crank, attach calibra-
tion crank to coupler on right hand side of gauge
wheel jackshaft using retaining pin.
