Abstract

For use with farm implements having tillage discs, there is provided a disc scraping assembly in which the swingable arm for supporting the scraper blade is provided with a hat section mount together with a compression spring to yieldably hold the blade against the disc. Alternate connections are provided between the arm and the tension means such as to selectively permit use of the assembly in connection with either of a pair of discs depending upon which direction the concave surface of the disc is facing in the implement. The blade is rotatably mounted on the arm through use of a dirt clearance slot which, in turn, releasably receives a pair of yokes freely rotatable on the arm and releasably interlocked with the blade. Removable cross pins in the arm cooperate with the yokes in preventing displacement of the scraper blade axially of the arm.
