The embodiments herein provide a method for separating fine fractures from coarse fractures, comprising the steps of generating an area of low air pressure beneath a sieve positioned within a centrifugal scattering device followed by ingesting a mixture of air, coarse fractures, and fine fractures into the centrifugal scattering device. The method would preferably continue by causing a guide to rotate around an interior cavity of the centrifugal scattering device while forcing fine fractures through the sieve using the low air pressure and gravity, into a fine fracture collector. Preferably coarse fractures are permitted to travel along the sieve, guided by the guides, to a coarse fracture collector which is separate from the fine fracture collector.

A harvester may include a chassis, a first separation frame movably supported by the chassis and upon which crop material is deposited, a second separation frame movably supported by the chassis and upon which the crop material is deposited; a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame and an adjustable link operably coupled between the separation frame and the chassis. The adjustable link facilitates adjustment of an orientation of the first separation frame independent of an orientation of the second separation frame without altering a reciprocation stroke distance.

A harvester includes a chassis, a separation frame movably supported by the chassis and upon which crop material is deposited, a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame, a control system, a sensor programmed to produce a signal indicative of a tilt of the chassis relative to a gravitational direction, and programmed to provide the signal to the control system, and an adjustable link operably coupled between the separation frame and the chassis to adjust a pivot point of the separation frame. The control system is programmed to determine a change in tilt of the chassis based on the signal from the sensor. The controller is programmed to adjust the adjustable link to modify the pivot point of the separation frame in response to the change in tilt of the chassis.
