An attachment for connection to a harvester comprises a plurality of picking devices (2) arranged next to each other and in a distributed manner along the working width. Each picking device (2) has a picking gap (6), below which are disposed at least two picking rotors (10) which can be driven to rotate in opposite directions, the picking rotors (10) being provided with flutes (12), which project in a radial direction beyond the rotor casing (16) and the enveloping circles (20) of which mesh with each other. To propose a way of easily adapting the picking rotors to different harvesting conditions without having to replace them all, the invention proposes for one or more shear bars (18) which are releasably connected to the picking rotor (10) and/or to the flutes (12) to be inserted in the intermediate space (22) between adjacent flutes (12) of a picking rotor (10), the shear bars filling portions of said intermediate space during a rotating movement of the picking rotors (10).

Some embodiments are directed to methods and apparatus for separating corn kernels from a cob of an ear of corn, each of the corn kernels defining a base portion that is attached to an exterior of the corn cob. A circular blade defines an axis and a central aperture around the axis that is open at front and rear ends. A holder retains the ear of corn along the axis of the circular blade, and a driver moves the ear of corn along the axis towards the blade, to enable the blade to contact the base of the corn kernels from the corn cob, and thereafter move the cob that has been separated from corn kernels through the blade central aperture. The driver receives manually input force and increases power of the input force to result in increased force applied to the corn cob.

A dust restrictor is provided for eliminating dust and dirt accumulation between surfaces. The dust restrictor includes at least one dust restricting element and an attachment means. The dust restricting element is disposed in a dust accumulating area of an arrangement. The attachment means is provided for fixing each of the dust restricting elements to the dust accumulating area. The dust restrictor can minimize an accumulation of debris, reduce the down time of a machine due to debris accumulation, and also increase life of bearing and motors operating a machine.

A harvester implement includes a crop processor positioned to receive the crop material from a head unit and process the crop material to alter a characteristic of the crop material, e.g., a cut length or a kernel processing score. An image sensor assembly is positioned downstream of the crop processor along a flow path of the crop material. The image sensor assembly is operable to capture a post-processing image of the crop material. A computing device is operable to execute a crop processing analysis algorithm to receive the post-processing image of the crop material from the image sensor assembly, and to analyze the post-processing image to determine an actual degree of processing to the characteristic of the crop material achieved by the crop processor. The computing device may then communicate a notification signal to an output indicating the actual degree of processing to the characteristic of the crop material.

A cracker roller disc has a first portion radially outward of the centre of substantially constant thickness, and a second portion radially outward of the first portion which second portion tapers towards the periphery of the disc. A plurality of upstanding ridges extending radially outward across the second portion on opposed faces of the disc are machined to define respective conical surfaces forming radially extending edges on opposed faces of the disc. The disc is provided with one or more circular or spiral grooves which cut across the edges in a substantially perpendicular direction to the edges. The grooves extend the effective length of each edge.
