DCFirst Claim
1. In combination, a farm implement including a frame and a plurality of row units mounted on the frame, each row unit including a tool, each row unit having a gauge wheel associated therewith, a trash blade mounted on the frame associated with each gauge wheel ahead of the associated tool, and means urging each gauge wheel and each trash blade toward contact with the soil, the trash blade being angularly displaced from the vertical and from the direction of travel of the associated gauge wheel to move trash from ahead of the tool to form a row of trash between adjacent row units.

Abstract
A farm implement having a frame and a plurality of row units mounted on the frame with each row unit including a tool. Each row unit has at least one gauge wheel associated therewith with a spring urging each gauge wheel into contact with the soil to be worked by the tools. A single trash blade rotatably is mounted on an arm pivotally mounted on the frame associated with each gauge wheel ahead of the associated tool. A spring continually urges each trash blade toward contact with the soil ahead of the associated tool, with the plane of each trash blade being angularly displaced from the direction of travel of the associated gauge wheel in the range of from about 22° to about 30° and being angularly displaced to the vertical in the range of from about 20° to about 30° to move trash from ahead of the tool to form a row of trash between adjacent row units.

19. In combination, a gauge wheel arm having a gauge wheel rotatably mounted thereon and means for mounting said gauge wheel arm to the frame of a farm implement, a trash blade mounting assembly having means accommodating mounting of said trash blade mounting assembly ahead of said gauge wheel to the frame of the farm implement for movement between a working position and a non-working position, a trash blade rotatably mounted on said trash blade mounting assembly, spring means for urging said gauge wheel and said trash blade into contact with the ground, said trash blade mounting assembly when mounted to the farm implement frame being constructed and arranged to position said trash blade angular relationship to said gauge wheel such that the plane of said trash blade is angularly displaced from the direction of travel of said gauge wheel in the range of from about 22°
- to about 30° and
