A row unit assembly for use with a corn harvester includes a first drive having an output shaft, a stalk roll that extends along a first axis and rotates about the first axis via the output shaft of the first drive. A second drive rotates a first drive member about a second axis that is substantially perpendicular to the first axis. A first conveyor extends around the first drive member and moves about the first drive member in response to rotation of the first drive member. A third drive rotates a second drive member about a third axis that is substantially parallel to the second axis. A second conveyor extends around the second drive member and moves about the second drive member in response to rotation of the second drive member.

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).

A row unit for a header of an agricultural harvester. The row unit includes a frame, a first deck plate assembly mounted to the frame, and a second deck plate assembly mounted to the frame. The first and second deck plate assemblies each include a deck plate, a plurality of deck plate segments extending from the deck plate and moveable between a first position and a second position relative to the deck plate, and a plurality of biasing members for biasing each respective deck plate segment. The row unit includes both operator controlled macro adjustment and automatic micro adjustment of a gap between the first deck plate assembly and the second deck plate assembly. The micro adjustment is achieved through biasing members biasing each respective deck plate segment.

Corn header (4) for a forage harvester (1) for harvesting stalk crops, having a plurality of mowing and infeed units (5), which each have a plurality of drum-like or chain-like mowing and infeed members (6), which are rotatable about a vertical axis and are drivable in a revolving manner, for severing the crop in a substantially horizontal direction from a field to be cultivated, wherein the mowing and infeed members (6) of a pair (11) of mowing and infeed units (5) arranged in the center between two sides (4a, 4b) of the corn header (4) are drivable in a revolving manner such that they have a tendency to convey crop out of a gap (12), which is formed between them, forwards away from an infeed (9) of the forage harvester (1), wherein a central separating member (13) for separating the crop is positioned in a substantially vertical direction in the region of the gap (12) between the mowing and infeed members (6) of the pair (11) of mowing and infeed units (5) arranged in the center of the corn header (4).

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 harvesting machine has a controlled subsystem that performs harvesting machine functionality, and a control system that controls the controlled subsystem. A header is mounted to the harvesting machine and has row dividers (that divide rows of crop stalks) and gathering chains. A set of crop loss inhibitors is mounted proximate a forward portion of each of the gathering chains, in a direction of travel of the harvesting machine. The crop loss inhibitors also include a sensor that senses a variable, indicative of a crop attribute, as each crop stalk passes through the set of crop loss inhibitors.

A row unit for a header of an agricultural harvester is provided. The row unit includes a frame, a first deck plate assembly mounted to the frame, and a second deck plate assembly mounted to the frame. The first and second deck plate assemblies each include a deck plate, a plurality of deck plate segments extending from the deck plate and moveable between a first position and a second position relative to the deck plate, and a plurality of biasing members for biasing each respective deck plate segment. The row unit includes both operator controlled macro adjustment and automatic micro adjustment of a gap between the first deck plate assembly and the second deck plate assembly. The micro adjustment is achieved through biasing members biasing each respective deck plate segment.

A stalk roll assembly for header of a combine harvester. The assembly includes first and second stalk rolls spaced laterally with respect to one another and rotating in opposite directions. Each stalk roll includes a frusto-conical nose and a cylindrical body. The cylindrical body includes a plurality of radially extending flutes. The nose includes a pair of helical flights. The plurality of flutes includes at least one cutting flute having a straight edge and a plurality of puncturing flutes with teeth. The stalk rolls are laterally offset a distance that permits the tips of the flutes to laterally overlap and the teeth of the puncturing flutes are longitudinally offset so the tips of the teeth are received between with the valleys of the teeth of the other stalk roll.

A chopper assembly having a discharge conduit. A first and a second beater disposed within the discharge conduit and a first door and a second door in the bottom wall of the discharge conduit positioned below the first beater and the second beater respectively.
