Abstract

A rotary scraper for the exterior of planter disks which is mounted on a bracket easily attachable to existing grain planters. The rotary scrapers are mounted on the front edge of double disk planter disks vertically centered with the planter disks and with at least one half of the scraper disk outside the circumference of the planter disk.

Claims

1. A scraper for planter disks wherein:

said planter is comprised of at least two planter disks rotatably mounted in side-by-side relationship and angled towards each other so as to form a furrow upon rotation of said planter disks;

a generally U-shaped support bracket adapted to be mounted on said planter;

scraper disks rotatably mounted to said support bracket; and

said scraper disks being adapted to be mounted in spaced relationship to said planter disks so as to be in close proximity to the exterior of said planter disks and so that at least one-half of said scraper disks extend beyond the circumference of said planter disks so that said scraper disks rotate about an axis which is substantially in the same horizontal plane as the axis about which the planter disks rotate.

2. The scraper as set forth in claim 1, wherein:

said support bracket is comprised of a base member mounted to said frame and vertical members extending downward from said base member;

said scraper disks being mounted on said vertical members; and

said base member having a notch of sufficient depth to fit said base member around a drill tube.

3. The scraper as set forth in claim 2, wherein:

said scraper disks are rigidly rotatably mounted to said support bracket.

4. The scraper as set forth in claim 1, wherein:

said scraper disks are saucer-shaped and are further mounted at an angle relative to said planter disks so that the edge of said scraper disks faces the exterior of said planter disks.
