Description of the Folding
No-Till Drill Seed Box Agitator

The Seed Box Agitator is an option that can be ordered
to fit 1995 2-Section No-Till Drills model numbers; 2410,
2420, 3010, & 3020..

118-456A 30’ Folding No-Till 7 1/2" Agitator

118-457A 30’ Folding No-Till 8" Agitator

118-458A 30’ Folding No-Till 10" Agitator

118-459A 24’ Folding No-Till 7 1/2" Agitator

118-460A 24’ Folding No-Till 8" Agitator

118-461A 24’ Folding No-Till 10" Agitator

The Seed Box Agitator is designed to stir the seed di­rectly above the metering cups. It is intended to cut down
on the "bridging" of light fluffy seeds, and help to sepa­rate individual soybeans that become sticky from
inoculant. The Seed Box Agitator will not guarantee

consistent seeding of hard to meter seeds such as
Brome Grass or "bin run" seed that contains crop
residue.

The Agitator is an option that may be ordered with your
drill, or ordered and installed at a later time by you or
your dealer.

Section 2 Assembly Instructions & Set-Up

NOTE: While using the following text to install your
Agitator, you may need to refer back to the parts sec­tion of this manual for more details and for positive
identification of related items not mentioned in these
instructions.

Refer to Figure 2-1:

If your drill is equipped with a Small Grass Seeder at­tachment, a majority of the drive system is already in
place. If your drill is not equipped with a Small Grass
Seeder one of the following drive bundles must be or
dered with any agitator assembly:

197-115A 30’ Small Grass Seeds

& Agitator Drive Assembly

197-116A 24’ Small Grass Seeds

& Agitator Drive Assembly

-

Drive Installation

If your drill does not have 197-115A or 197-116A re­fer to the following:

Install the two 1" bore bearings (#1) on the end of the box
frame and frame drive plate using the flangettes (#2) and
5/16"-18 x 1" round head square neck bolts (#3) and

hardware as shown.

Slide the 1" jackshaft (#4) thru the bearing mounted on
the end of the box frame. Slip the shaft through the 19
tooth sprocket (#5) and the 22 tooth sprocket (#6). Then
slip it through the bearing attached to the frame drive
plate.

Attach the drive chain (#7) from the gearbox to the 1"
jackshaft around the 22 tooth sprocket (#6). Align and
tighten the chain and idler sprockets.

If your drill is assembled with 197-115A or 197-116A
Small Grass Seeders and Agitator Drive assembly
refer to the following:

Remove the 1" jackshaft thru the box frame end panel.
Attach the 19 tooth sprocket (#5) to the jackshaft and
slide the jack shaft back thru the box frame end panel.

Final Drive Connection

Route the drive chain (#9) back through the cutout in the
box, around the agitator sprocket (#8) and back to the 19
tooth sprocket (#5) as shown. After connecting the
chain, check alignment of the sprockets. Move the agita
tor sprocket (#8) if needed and tighten the two set
screws on the sprocket. Position and adjust the idler
sprockets as shown.

Once all chains are aligned, tighten all the hardware.

Refer to Figure 2-4: Slip one paddle (#1) over the hex
shaft directly above a feeder cup. Slip a 1/4"-20 x 2"long
hex flange bolt (#2) through the paddle and secure with
a 1/4" hex flange lock nut (#3). Before tightening a pad­dle or group of paddles, carefully rotate the drive system
to make sure paddles do not hit the tray dividers.

After checking for interference, torque the paddle bolts to
9 ft. lbs. (108 in lbs.)

Install the next paddle over the next feeder cup. Index
this paddle 1/6th of a turn by sliding it onto the next set of
flats. Continue the installation, using the next set of flats
for each paddle. The fully assembled shaft will have a
built in spiral when finished.

Section 3 Maintenance & Lubrication

Maintenance

Proper servicing and adjustment is the key to the long
life of any farm implement. With careful and systematic
inspection, you can avoid costly maintenance, time and
repair.

1. After using your attachment for several hours, check
all bolts to be sure they are tight.

2. Adjust idlers to remove excess slack from chains.
Clean and use chain lube on all roller chains as
needed.

Storage

1. Lubricate and adjust all roller chains.

2. Store the drill inside if possible for longer life.

Check all drive chains, sprockets, keys and pins.

The agitator will not guarantee perfect seeding of trashy, wet or sticky material.

Check tire pressure. Proper inflation is listed in the “Tire Inflation Chart", Section
