A wheel scraper employs a support arm for mounting to a frame of an agricultural implement and a bowl-shaped scraper member rotatably supported on the support arm in a position facing the open end of the bowl toward the wheel just outside the periphery thereof. The support arm is twisted in order to set a circumferential point of the bowl that trails an opposing circumferential point thereof in a rotational direction of the wheel to be scraped closer to the wheels periphery than the opposing point. A slot-shaped hole is used in the rotational coupling of the bowl to the support arm to allow the rotational axis of the bowl to be laterally adjusted relative to the mid-plane of the wheel. In one embodiment, a U-bolt attachment of the mounting arm to the frame also employs slot-shaped holes to allow adjustment of the support arm's position.
