Patent ID: 7849932

Claim:
An assembly for use with a farm implement towed by a vehicle, the implement including a main frame and a hitch that extends from the frame for linking to the vehicle, the assembly comprising: a T-shaped wheel support member including a neck member extending along an axis and two arm members, the neck member including first and second oppositely directed ends, the arm members extending from the second end of the neck member in substantially opposite directions, the first end of the neck member mounted to the frame for pivotal movement about a substantially horizontal axis; first and second ground engaging support wheels mounted at distal ends of the first and second arm members, respectively; an anchor member extending from the frame; a first hydraulic lift cylinder linked between the anchor member and the T-shaped support member proximate the arm members for adjusting a distance between the arm members and the frame; a hydraulic steering cylinder mounted to the wheel support member below the frame and linked to the first and second support wheels for controlling steering of the wheels, the steering cylinder including a piston terminating at a terminal end and being movable between an extended position and a retracted position; an elongated intermediate pivot member having first and second opposite ends and a central portion therebetween, the first end pivotably connected to the wheel support member; a first elongated link having a first end pivotably connected to the central portion of the pivot member and a second end operatively connected to the first wheel; and a second elongated link having a first end pivotably connected to the central portion of the pivot member and a second end operatively connected to the second wheel; wherein: the terminal end of the piston of the steering cylinder is pivotably connected to the second end of the pivot member such that the first and second wheels point towards a first side of the axis of neck member with the piston in the extended position and such that the first and second wheels point towards a second side of the axis of neck member with the piston in the retracted position; the anchor member extends to a distal end on a side of the frame opposite the side on which the steering cylinder is mounted and wherein the first lift cylinder is linked to the distal end of the anchor member; and said assembly having actuation during transport steers rear of the implement independent of said vehicle to facilitate entry to or egress from confining roadways or approaches.
