Patent ID: 7540522

Claim:
A steering connection assembly interconnecting a vehicle train arrangement comprising a tow vehicle steering a turn angle from a forward direction of travel, a first detachable implement having a tow bar pivotally interconnected to rotate about a first vertical axis at a draw bar of the tow vehicle, and a second detachable implement towed rearward of the first detachable implement, the second detachable implement including at least one wheel assembly in moveable support of a frame and a second tow bar having a forward end pivotally connected at so as to rotate about a second vertical axis relative to the frame of the first implement, the second tow bar also including a rearward end fixedly attached at the frame of the second detachable implement, the steering connection assembly comprising: a hitch coupling member fixedly attached at so as to move with the draw bar; and a drive linkage pivotally connected at, so as to rotate about a third vertical axis with respect to, the hitch coupling member, wherein the third vertical axis spaced from the first vertical axis, wherein in response to the turn angle of the tow vehicle, the hitch coupling member moves the drive linkage so as to cause a steering linkage to move the wheel assembly of the second detachable implement in a turn direction opposite the turn angle of the tow vehicle from the forward direction of travel, and wherein the steering connection assembly attaches the second implement in a manner that restrains a central longitudinal axis of the second implement from not being generally inline with a central longitudinal axis of the first implement, wherein the hitch coupling member is keyed to define a first leg and second leg to receive the draw bar of the tow vehicle therebetween.
