Abstract
Abstract A powered rotor is provided on the cropward divider of a rowcrop harvester and is driven at a peripheral speed slightly faster than the speed of the conveyor chain mounted on this divider. The rotor is located intermediate the ends of the divider and projects upwardly with a forward inclination through an inwardly inclined sheet metal panel of the cropward divider. The rotor comprises preferably four equally spaced paddles defining undulant surface area which are effective to shake the stalks which ride up the divider from entanglement with the standing crops in the adjacent row. A stripper bar is provided on the inward side of the rotor to remove the crops therefrom.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
179 words
A row cRop gathering head for a forage harvester comprising: a plurality of dividers defining plant passage means therebetween, one of said dividers having a front end, a rear end, and an upper edge angling upwardly from said front end to said rear end, said one of said dividers providing a crop guiding surface sloping from the adjacent plant passage means laterally diagonally upwardly to said upper edge; a powered plant-disentangling rotor having a peripheral undulating surface, said rotor being supported on said one of said dividers approximately medially between the front and rear ends of said divider, said rotor projecting upwardly through said crop guiding surface, said crop guiding surface subtending said rotor in a diagonal plane and exposing a relatively large surface area of the rotor on the passage means side and a small surface area on the opposite side; and, a stripper bar adjustably mounted on said divider adjacent said rotor on the passage side thereof, said stripper bar having a stripping edge parallel to and in close proximity to the outer periphery of said rotor.
Claim 2
Dependent Claim
