PRECISION SOWER
ABSTRACT OF THE DISCLOSURE
A precision sower is described which has the capability
of sowing seeds in single in rows parallel to the direction
of travel of the sower and in parallel rows normal to the
direction of travel. The sower comprises a hollow rotatable
drum provided with series radial holes, each series being in
the same plane, and an internal source of vacuum. Pins
positively displace seeds from the holes at a predetermined
point in the rotation of the drum. The pins are actuated by
a cam surface during normal rotation of the drum. The sower
can be used in association with rollers, coulters and other
implements to assist in the sowing operation.
This device enables seeds to be sown singly and to be
precisely spaced both along the path of travel and trans-
versely to that path.
