A scraper is disposed aft of and in closely spaced relation to a gauge wheel such as attached to an agricultural implement as in a planter row unit to remove soil from the wheel as the implement traverses a field. Maintaining the gauge wheel free of soil ensures proper height of the implement relative to the soil surface. The scraper includes a flat plate adjustably attached to a mounting assembly which allows for spacing between the plate and periphery of the gauge wheel to be adjusted as the plate wears with use. A leading edge of the plate disposed immediately adjacent the gauge wheel is contoured to closely match the gauge wheel contour for efficient soil removal. The mounting assembly includes a gauge wheel arm and a scraper arm rigidly coupled together at respective ends thereof and pivotally mounted to the implement where the two arms are connected together. The scraper plate is attached to a second opposed end of the scraper arm, while the second opposed end of the gauge wheel arm is attached to the gauge wheel's axle, or spindle. The entire assembly is free to pivot on the implement as the gauge wheel encounters obstacles and irregularities in the field. Rigidly connecting the gauge wheel and the scraper together while allowing both to pivot about a common axis ensures that the scraper remains a fixed distance from the gauge wheel's periphery regardless of the position of the gauge wheel.

[ I claim:] [1.] Apparatus for removing soil from a gauge wheel attached to an agricultural implement and having an axle, said apparatus comprising:a gauge wheel support arm having first and second opposed ends, wherein said first end is capable of being coupled to the axle;a scraper support arm having a collar at one end and an opposed end, wherein the collar of said scraper support arm is capable of being coupled to the second end of said gauge wheel support arm;said second end of said gauge wheel support arm having a section of reduced diameter extending therefrom which fits within said collar on said scraper support arm,means for pivotally connecting the second end of said first support arm and the collar of said scraper support arm to the agricultural implement for allowing vertical displacement of the gauge wheel as the gauge wheel encounters obstacles and irregularities in a field traversed by the agricultural implement; anda scraper plate attached to the opposed end of said scraper support arm and maintained in closely spaced relation to the periphery of the gauge wheel as the gauge wheel undergoes vertical displacement for removing soil from the gauge wheel.
