Agitator Blades (Optional Cage
or Brushes)
Agitator Blades
are supplied as standard on your
seedbox. They should operate leaving a slight clearance
with the bottom of the seedbox.
Agitator Brushes
(Optional) in the seedbox sweep the
bottom of the box to control the flow of seed. However, if
they exert too much pressure on the bottom of the box,
chain breakage and excessive brush wear can possibly
result. To overcome excessive pressure of the brushes on
the bottom of the box, the bolts holding the triangular cast
iron bearings can be loosened and the bearings raised to
reduce excessive drag. The holes in the bearing are
slightly larger than the bolts holding them, thus making an
adjustment possible.
Cage Agitator
(Optional) operates similar to blades.

Figure 2-1: Shaft Rotation
IMPORTANT
Before proceeding with any agitator installation, be
sure to note the direction of the shaft rotation on your
seeder. See Figure 2-1.
1. Remove two bolts which hold end bearing on the right
end of the right seedbox.
2. Slide the shaft out of the right end.
3. Agitators should be installed with careful attention to
the direction of shaft rotation as the seed rate will be
reduced if they run “backwards”. In addition, brush
agitators will be damaged if not run in the proper
direction.
CAUTION
4. With the agitators properly seated in the boxes,
replace the drive shafts. Replace washers as needed
for fit.
5. Check to be sure agitators rotate freely. Some
seeders may have bolts extending into the seedbox
causing inference. These bolts will need to be
shortened.
6. Apply Important Decal 5D505 to the front seedbox
visible by the tractor driver.
