A fruit sizer employs an in-feed chute which divides fruit among a plurality of sizing runs evenly. This is accomplished by locating the apices of the dividers with respect to a grade table, or other feed mechanism, so that the fruit is divided evenly. A conveyor system uses slanted rollers which are arranged with respect to a drive roller so that each side of the conveyor belt is placed in tension equal to that of the other side of the conveyor belt. This arrangement prevents undue stress on the conveyor belt and prevents the tendency to walk off the rollers. The sizing rollers are driven by a drive train which employs a single flexible belt and may be raised or lowered with the sizing rollers, without affecting the driving belt. Several embodiments of the drive train are disclosed.
