Wing positioning apparatus

Abstract

A farm implement supported by at least one wheeled support mounted on a pivot arm extending from a wing and at least one tracked support on a main carrier. The tracked support can be rotated about a primary rotational axis and the wheeled support being rotatable about a secondary rotational axis. The pivot arm can be rotated to position the wheeled support to elevate or lower the wing. The rotational of the pivot arm also changes the alignment of the secondary rotational axis of the winged support relative to the primary rotational axis of the tracked support to prevent berming when maneuvering the farm implement.

What is claimed is: 
     
         1 . A farm implement, comprising:
 a main carrier including a tracked support rotatable about a primary rotational axis;   a wing pivotably connected to the main carrier; and   a wing support assembly, comprising:
 a pivot arm rotatably mounted to the wing, and 
 at least one wheeled support positioned on the pivot arm; 
   wherein the pivot arm is rotatable to position the wheeled support in at least an operational position and a turn position, wherein the wheeled support is positioned such that the secondary rotational axis is forward of the primary rotational axis in the operational position and the wheeled support is positioned to align the secondary rotational axis is generally aligned with the primary rotational axis in the turn position.
