Abstract
Abstract A trailer carrier includes a tractor-drawn, fore and aft elongated bed supported on ground engaging wheels transversely spaced to conform to furrow center lines in a row crop field being mechanically harvested. The bed is tiltable between a first position wherein the after end of the bed engages the ground to afford an on-ramp and an off-ramp for a roadworthy trailer and a second position wherein the bed is substantially horizontal while the carrier transports the superposed trailer alongside an operating harvester to receive the crop being harvested. Projecting forwardly from the carrier is a fixed upper frame carrying a winch to facilitate trailer movement onto and off the carrier and a pivoted lower frame for connection to the tractor, a jack being interposed between the upper and lower frames to move the bed between the first and second positions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
184 words
A trailer carrier for transporting a roadworthy trailer through a row crop field, said trailer having road wheels of a normal roadway tread width, said trailer carrier comprising: an elongated bed of a width to support and transport said trailer and having ground engaging wheels laterally spaced apart a distance greater than said normal roadway tread width; hitch means pivotally connected to said bed on a transverse axis for connecting said trailer carrier to a tractor having laterally spaced ground wheels of a tread width less than that of said carrier, said hitch means being skewed relative to said bed and when engaged with said tractor the wheels on one side of said carrier are longitudinally aligned with the wheels on the corresponding side of said tractor; and actuator means connected to said bed and to said hitch means for selectively tilting the bed between a first position in which the after end of the bed engages the ground to afford an on-ramp and an off-ramp for the trailer and a second position wherein the bed is substantially horizontal to transport a trailer thereon.
