A self-propelled module builder comprising a frame in which cotton or other compressible material is deposited. A compacting mechanism is mounted on the open top of the frame to compress the material into a module. The frame has a side frame structure on each side thereof. Each side frame structure includes a walking beam that is pivotally connected centrally between the ends thereof by an hydraulic jack, which is pivotally attached to the adjacent side frame structure. The ends of the walking beam are connected by pins to parallel spindle tubes. Each spindle tube is constrained for vertical sliding movement by an upright guide, which is fixed to the associated side frame structure. Drive wheels are mounted at the lower ends of the spindle tubes through respective spindles. With the frame lowered, a module is made on the ground to be transported to a suitable facility. When the rectangular frame is raised, the module builder is capable of traveling to another location. On each spindle tube is mounted a motor to drive the associated drive wheel through a sprocket and chain arrangement. Thus, each drive wheel is driven by an independent motor, while the module builder retains the full action of a walking beam. A retractable front wheel serves as a steering wheel for the module builder.
