A pair of arms are pivotably affixed at their upper ends to a shaft secured to brackets depending from the underside of a combine header or other agricultural machinery, the arms being disposed at an angle of about 45.degree. with the ground. A roller is secured across the lower ends of the arms, the roller having a width slightly greater than the width of the row of the crop to be harvested. The entire assembly is connected to a plate which may be welded or otherwise secured to the machine ahead of the tires. A compression spring is affixed at its upper end to the plate and at its lower end to a cross-piece secured across the arms at about their midpoint, the spring urging the roller against the ground so that the stubble will be forced substantially flat against the ground as the large tires of the combine pass over it. The considerable damage to such tires which otherwise occurs from stubble wearing the tread is eliminated or reduced.
A stubble flattener for attachment to the header of a combine comprising a ground wheel for said header and a pneumatic tire subject to damage by stubble, a plate adapted to be fastened to a header, a pair of arms pivotally mounted at their upper ends relative to the plate, a roller secured to the lower ends of the arms immediately in front of said tire and substantially as wide as said tire, the roller being disposed so that it runs along the ground to flatten stubble so that it does not injure said tire, and a compression spring disposed between the plate and the arms for urging the roller against the ground to flatten stubble.
