ABSTRACT:
An apparatus for lifting crops ahead of a harvesting machine which includes a mounting bracket and a pick-up bar pivotally connected by a linkage, and a guide frame for guiding the rear portion of the pick-up bar so that as the pick-up bar swings backward in relation to said mounting bracket, a front end portion of the pick-up bar is lifted. An alternate linkage adjustable in length is also disclosed. An adjustable abutment limits the forwardmost position of said pick-up bar, defining a normal operating position of the apparatus. The apparatus is arranged and constructed so that gravitational forces acting on the pick-up bar will always urge the pick-up bar toward the forwardmost position. The pick-up bar includes a smooth lower surface defining a runner for traveling in close proximity to the ground.
