A-Cylinder

B-Concave

C-Overshot Beater

D-Tine Separators

Cut crop is fed up the feeder house then through the cylinder (A) and concave (B).

An overshot 8 wing beater (C) moves the crop material into two tine separators (D) that spin in opposite directions, dividing and spinning the crop material rearward. Tines mounted on the double separators engage and comb the crop material.

Fixed directional vanes, mounted on the inside of the housing of the tine separators, help move the material several times past the separator grates (spiral movement). The combing action of the spinning tines, along with centrifugal force, provides maximum separation of the heavy grain from the mat of straw.

All along the way free grain falls onto the grain conveyor located under the tine separator grates. By the time the crop material reaches the rear of the separating grates, it is free of all trapped grain. The grain conveyor carries the grain to the QUADRA-FLO ™ cleaning system for final cleaning.

Let the tine module do as much of the threshing as possible and do the fine tuning with the cylinder and concave.

In easy to thresh crops, the tines can do much of the threshing while in harder to thresh crops like hard spring wheat, the tines will do very little threshing and the cylinder/concave will do most of it.
