Claim:
A dual chassis frame with multi-directional transmission, comprising: a) a rear chassis frame assembly; b) a front chassis frame assembly; c) a pair of hydraulically retractable central bars to selectively connect and disconnect said front chassis and said rear chassis to form a unified, stable rigid chassis to a independently movable, yet coupled multi-directional front chassis and rear chassis; wherein said rear chassis frame assembly comprises side frame members having a means for securing said central bars to said rear chassis frame assembly, wherein said means for securing said central bars is a pair of pressure locks; d) a central multi-directional mechanism connecting a medial portion of said front chassis to a medial portion of said rear chassis to selectively allow independent horizontal and vertical movement of said front and rear chassis for traversing uneven terrain when said front chassis and rear chassis are disconnected from each other by said hydraulically retractable central bars; e) a pair of fixed wheels disposed on a rear portion of said rear chassis and a pair of wheels disposed on a front portion of said front chassis; and f) means for increasing the distance between said front chassis and said rear chassis during dual chassis operation.
