FOLDING IMPLEMENT CARRIER
First Claim
1. An implement carrier comprising an elongated main frame having opposite ends, means intermediate said ends for connecting said main frame to a propelling vehicle, pivotal connecting means spaced inwardly from at least one of the ends of said main frame, bridge means connected to said pivotal connecting means and extending outwardly of said one end of said main frame, an auxiliary frame fixed to the outer end of Said bridge means, means for swinging said bridge means in a generally vertical plane about said pivotal connecting means to selectively move said auxiliary frame to operative or inoperative positions, said auxiliary frame having an end which abuts said one end of said main frame when said auxiliary frame is in operative position, an abutment on said main frame and spaced from said pivotal connecting means, a portion of said bridge means engaging said abutment to resist horizontal movement of said auxiliary frame and reduce shear forces on said pivotal connecting means when said auxiliary frame is in operative position, and means for mounting at least one implement on each of said main and auxiliary frames, whereby said auxiliary frame is substantially co-extensive with said main frame in operative position and disposed inwardly of the end of said main frame in inoperative position.
