Range Sprockets
Select the correct drive speed range sprockets for your
seed by referring to “Seed Rate Charts,” beginning on
page ci.
Refer to Figure 23
Loosen idler bolt (1) and remove chain. Remove
retaining pins from shafts and install speed range
sprockets as necessary.

NOTE: Make sure the correct sprockets have been
installed in the DRIVER and DRIVEN locations as
shown.
Reroute chain over sprockets and idlers as shown. Move
idler into chain so chain has 1/4-inch to 1/2-inch slack in
its longest span. Tighten idler and install retaining pins.
Set the same drive range sprocket combination on both
sides of drill.
For correct drive type, refer to seed-rate charts beginning
