ABSTRACT:
The present invention is an improved seed sower unit and an improved seed supply hopper for the head. Opposed vacuum disc-type sower units are mounted in a frame. A seed hopper is mounted on a separate subframe. The hopper subframe has mounting notches which rest on stub pins projecting from the main frame. A latch mechanism holds the seed hopper subframe in place during operation. By opening the latch, the subframe with the seed hopper can be lifted vertically from between the sower discs to permit ready access for cleaning or repair. The seed hopper portion has a sloping bottom member adapted to fit between the sower discs to form a seed trough. This sloping member has a gate so that seed can be easily drained from the system into a container without loss. An optional second gate enables the seed hopper to be isolated from the seed trough. By making the seed hopper vertically removable, the sower units may be located in close proximity to each other, thus enabling similarly close crop row spacing.
