A mulching device is equipped with a tool that can be set into rotation about an axis of rotation tilted upwards and to the rear in order to process plant stubble. The rotational direction of the tool can be selected such that the tool is pressed back out of the ground by the driving torque in the event of an overload.

A system for monitoring an extractor fan of an agricultural harvester includes an extractor fan having a shaft configured to be coupled to a rotational drive source for rotationally driving the shaft, a fan hub coupled to a lower shaft end of the shaft such that rotation of the shaft rotationally drives the fan hub about a fan hub axis, with the fan hub extending between an upstream side and a downstream side along the fan hub axis, and fan blades coupled to and extending radially outwardly from the fan hub. The system further includes a sensor that generates data indicative of acceleration of the extractor fan. Additionally, the system includes a computing system that determines an acceleration of the extractor fan based at least in part on the data, and determines whether the extractor is imbalanced based at least in part on the acceleration of the extractor fan.

A body unit of a grass cutter incorporates a deceleration mechanism unit. The deceleration mechanism unit has a ring gear-side member, a sun gear-side member, a retainer board member, and a small gear. Eleven rollers mounted on the retainer board member are each provided in a gap between a ring gear-side guide and a sun gear-side guide, and engagement portions of the rollers are in contact with both the ring gear-side guide and the sun gear-side guide. The small gear engages with both a ring gear and a sun gear.

An agricultural system includes a tow bar, a first row-cleaning device, and a second row-cleaning device. The first row-cleaning device is attached to the tow bar via a first frame and includes a first roller device in a trailing position relative to a first furrow-opener disk and configured to crush standing residual plant matter along a first path on a field. The second row-cleaning device is attached to the tow bar via a second frame and includes a second roller device in a trailing position relative to a second furrow-opener disk and configured to crush standing residual plant matter along a second path on the field. The second roller device is offset longitudinally from the first roller device.

A vegetation chopping roller for an agricultural land roller implement including a drum body having an outer periphery which is generally cylindrical about a drum axis of rotation and a plurality of protruding mounting flanges upon which chopping blades are mounted using threaded fasteners. A seating surface is fixedly supported in relation to the drum body in association with each blade which receives the inner edge of the associated blade abutted thereon such that the threaded fasteners are substantially isolated from shear forces by the abutment of the blades with the seating surfaces.

A swather includes a swath compression panel with a downwardly and rearwardly inclined undersurface for applying a downward compression force on the swath between the front and rear wheels. A mounting assembly includes an actuator operable in response to a speed and/or direction of travel of the tractor for raising the panel to a retracted position under the tractor. A bottom stop halts downward movement of the actuator before the panel engages the ground. The panel includes an upwardly and rearwardly inclined curved rear portion to smoothly release the compressed crop. The panel is mounted on the tractor frame at a position thereon rearward of a transverse beam connected to the front wheels so that the swath is released from the discharge opening of the header and can expand for discharge to the ground before the swath is engaged by the front end of the panel.

A header assembly for a harvesting machine comprising a primary cutter head for cutting the crop, and a feeder for feeding the cut crop into the mouth of a crop processing mechanism. The assembly further comprises a secondary scissor-action cutter head trailing behind the primary cutter head for cutting stalks left behind by the primary cutter head, the secondary cutter head coupled to the rear of the header and supported by ground engaging rollers. The rollers include at least one support cylinder having a circumferentially discontinuous ground engaging outer surface operative to perform a preliminary processing of at least one of the crop residue and the soil.

A header for harvesting stalk-like plants includes a number of gatherer assemblies arranged side by side for cutting off and conveying plants to a picking device arranged downstream of the gatherer assemblies. The picking device extends transversely to a direction of travel over the entire working width of at least one half of the header and includes a picking gap and stalk roll below the picking gap to separate fruits from the plants and to deliver them for a separate utilization.

A corn kernel harvesting device and method thereof is provided. As the corn kernel harvesting device, or corn shucker, moves from a first configuration to a second configuration, the device separates corn kernels from its respective inner core, such as a corn cob. The corn kernel harvesting device comprises an ejection assembly, harvesting assembly, discharge assembly, and is configured to enable a user to remove corn kernels efficiently and consistently from a corn cob.
