ABSTRACT:
An agricultural machine for smoothing ruts, such as are produced in a field by center pivot sprinkler irrigation systems, comprises a pair of rotary tillers arranged in a unique frame for traveling over and along respectively opposite sides of the rut as such tillers are rotated toward each other to break up clods of soil ridged above the rut at opposite sides thereof and to largely fill and smooth the rut. A guide shoe carried by the frame midway between the rotary tillers is preferably provided to travel along the rut and maintain the rotary tillers at proper working positions, and a hood with outriggered side walls hinged thereto for outward swinging movement preferably covers the rotary tillers.
