ABSTRACT:
A transversely and linearly elongated tractionally supported tool-carrying frame for agricultural implements having caster wheels which are shiftable individually and vertically relative to the frame to move the latter, and consequently the tools, between raised inoperative and lower earth-working positions. A central tractor hitch on the frame enables the latter to be pulled in broadside fashion forwardly for earth-working purposes when the frame and tools are in their lowered earth-working positions, and a second tractor hitch at one end of the frame enables the latter to be pulled linearly sidewise for transport purposes when the frame and tools are raised. A salient feature of the invention resides in a novel arrangement for automatically latching one of the caster wheels against free caster trailing during such sidewise transport movement of the implement to thereby lend a stabilizing influence to the implement and inhibit side sway.
