Claim:
An agricultural implement comprising: a tool bar adapted to be coupled to a prime mover, the tool bar having an inner section and at least one outer section; a plurality of row units coupled to the inner and the at least one outer section of the tool bar, wherein the at least one outer section is coupled to the inner section in a manner that allows the at least one outer section to be raised to a position generally above the inner section; a central fill bulk assembly having at least one hopper in flow communication with the plurality of row units to supply product to the row units, the central bulk till assembly connected to the tool bar rearward of the plurality of row units, and wherein the central bulk till assembly includes: a tool bar connecting member; a cradle supporting the at least one hopper; a pair of wheels supporting the cradle above a surface; hydraulic cylinders configured to raise and lower the cradle between a lowered, field position and a raised, transport position; a pair of parallel linkages connected between the tool bar connecting member and the pair of wheels, wherein each parallel linkage includes an upper link and a lower link, and wherein the upper link and the lower link cooperate to maintain a consistent geometry of the cradle as the hydraulic cylinders raise and lower the cradle; each of the parallel linkages having a fixed length; and a pair of support arms interconnected between the tool bar connecting member and the cradle, each support arm extending at an angle from the tool bar connecting member such that each support arm is not linearly aligned with the tool bar connecting member; the support arms having a fixed length.
