Agricultural separating device and agricultural separator

An agricultural separating device having a starshaft comprising a row of resilient starwheels mounted on a rotatable shaft and having radially-extending, flexible fingers, and rings mounted between adjacent starwheels, said rings being formed of a rigid material and having an outer diameter that is spaced radially outward from the shaft over 40-80% of the radial length of the fingers of the starwheels outward from the shaft without the rings engaging the fingers over the 40-80% of the radial length in a manner which might interfere with the flexing of the fingers so as to close off the radially inner space between the fingers without reducing the length and therefore without reducing flexibility of the fingers.
