CROP CONDITIONING ROLLER FLUTE SHAPE

摘要

A forage conditioner includes a fixed bottom fluted roller and a top roller liftable from crushing position against the bias of a spring extendin g along the top roller. Flutes on the rollers are arranged with a first surface on one side which extends substantially radially outwardly to an apex and a second surface whi ch has a first portion parallel to a tangent of the roller and a second portion inclined inwardly to the roller surface at an angle significantly less than 90 degrees. The bottom roller is arranged with the first surface leading to carry the crop into the area between the rollers and the top roller is arranged with the first surface trailing. Thus the first surface of intermeshing flutes pass through a condition in which the first surfaces are substantially parallel and on opposite sides of a line joining the centers o f the rollers.
