Abstract: An agricultural machine for effectively mulching fodder within the space between crop rows with a single pass includes a frame having an adjustable tongue assembly for towing by a tractor at a preselected pitch and a retractable wheel assembly for transporting the machine over roads. Carriages attached to the frame carry freely rotating drums. Each carriage is slidable and rotatable on the frame for securing the carriage at a preselected orientation. Each drum has a rolling surface for engaging the ground being cultivated. Two carriages form a drum pair which straddles the crop row for permitting the drums within the drum pair to freely roll over ground on opposing sides of the crop row. A plurality of blades is carried on each of the rolling surfaces of the drums for penetrating the ground surface, with the blades extends radially outward from the axis of rotation. Each blade includes a cutting edge oriented with the blades on one drum orthogonal to the blades an the second drum of the drum pair.
