wheels of the cultivator so as thus to be revolved in its
bearings as the machine is moved along. A narrow chute or
conveyor encircles the lower portion of the drum at a point
beneath the holes in its side. This conveyor is formed with
a spout-shaped mouth that enters a hole formed in the top of
the seed-sower. Manure passing through the holes in the
drum will then gravitate down the chute conveyor and will
pass into the seed-sower and mingle with the seed fed into it
from the seed-box so as to fall with such seed into the drill.
