A scraper is provided for use on depth gauge wheels provided on planters for row crops such as corn, soybeans, cotton, beans, peanuts and the like. The scraper includes a scraper blade which is mounted at one end portion of an elongated arm for contacting the outer circumference of the depth gauge wheel and a second scraper blade that is mounted on the elongated arm at a position for preventing the accumulation of debris in the recessed well formed in the face of the depth gauge wheel. The other end of the arm is mounted by a bearing assembly to a hub provided on the depth gauge wheel. The bearing assembly is mounted coaxially with the axis of rotation of the wheel so that the arm remains stationary as the wheel rotates. In addition, the scraper blade remains in contact with the wheel as the wheel is moved in vertical and fore-and-aft directions. A support bolt is also received within an elongated opening presented by a U-shaped member mounted at the free end portion of the scraper arm to stabilize and reduce unnecessary movement of the scraper arm.
