Patent Images
1. A scraper for mounting to a tool bar of a farm implement having a rotating disk for tilling soil, the scraper comprising:
- a support mounted to the tool bar, the support comprising a shank having a first end and a second end and an upper stop and a lower stop in communication with the shank, the shank being non-movably attachable to the tool bar proximate a first end of the shank;
a shaft extending from the shank and having a central axis, a first end and a second end, the shaft pivotally attached to the shank proximate the second end of the shank wherein the shaft is positioned between the upper stop and the lower stop such that the upper stop and the lower stop limit the pivotal movement of the shaft; and
a scraper blade rotatably attached to the shaft proximate the second end of the shaft and wherein the scraper blade comprises a perimeter and wherein the shaft pivotally moves while the rotating disk is rotating to rotatably engage the perimeter of the scraper blade with a side surface of the rotating disk to remove soil and debris that accumulates on the side surface.

Abstract
A scraper for mounting to a tool bar of a farm implement having at least one rotating disk for tilling soil, including a support mounted to the tool bar and a shaft pivotally attached to and extending from the support where the shaft has a central axis. A scraper blade is rotatably attached to an end of the shaft and the scraper blade comprises a perimeter wherein the shaft pivots to rotatably engage a side surface of the rotating disk to prevent soil from accumulating on the side surface and prevents debris from accumulating between the side surface and the scraper blade.
