Merger extension chute and conveyor
A conveyor used with a harvester such as a wind rower has a chute at its discharge end with a deflection surface which controls the throw trajectory and thus the throw range of crop being cut. The orientation angle of the deflection surface relatively to the conveyor may be varied as a function of the particular crop throw characteristics to change the throw range of the conveyor as needed to form merged windrows of a particular crop while avoiding windrow widths which are too wide for efficient harvesting.
