For drills with small-seeds attachment:
Thread the drive chain (1) over the idlers on the idler assem-
bly (2), back through the cutout in the box, over and under
the agitator sprocket and idlers (3), around the small-seeds
sprocket (4), and back to front 12-tooth sprocket (5) as
shown.
On drills without small-seeds attachment:
Thread the drive chain (6) over the idlers on the idler assem-
bly (2), back through the cutout in the box, around the agita-
tor sprocket and idler (3), and back to the front 12-tooth
sprocket (5) as shown.
After connecting the chain, align sprockets. Move the agitator
sprocket if necessary and secure by tightening set screws.
Change the position of the idler sprockets as needed by adjust-
ing the 5/8-inch jam nuts. Move the idler assembly as needed
then tighten u-bolts. Move the 12-tooth front sprocket as needed
and secure by tightening set screw.
Once all the chains are aligned, tighten lock collars on the drill
shaft. Be sure to lock the collars against the bearings mounted to
the bearing plates.
