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 rod belt for rod belt conveyors of agricultural machinery, having rods situated transversely with respect to the running direction and in parallel to one another, the rods having flattened, perforated fastening areas with which they rest on tensile stress-resistant, continuous elastic belts revolving in parallel to one another, and are connected to the belts by rivets or similar fasteners which pass through the fastening areas and the belts. Thus, a rod belt is provided for rod belt conveying, which allows fastening of functional elements while avoiding the disadvantages stated for the prior art. This is achieved in that in the installed state of the rods, the fastening areas protrude beyond the inner edges of the belts with an overhang area, and have at least one hole in the overhang area for fastening a functional element of the rod belt.

A rod belt for agricultural machines includes at least three belts, fasteners, and rods. The at least three belts are pull-resistant, elastic, and continuous, and run parallel to one another. The at least three belts each extend in a direction of movement. The fasteners are connected to the belts. The rods are arranged perpendicular to the direction of movement and are parallel to one another.

An apparatus for harvesting rhizomes includes a chassis to move in a field. Coulter disks mounted on a forward end of the chassis break up soil on a top surface of the field. Digger blades aft of the coulter disks scoop clusters of rhizomes from the field with adhered soil. An inclined ramp on the chassis has a live bottom that pushes the rhizome clusters up the ramp in the aft direction including upright posts that force the clusters of rhizomes against depending obstructers extending downward from superstructure bars toward the live bottom. As the clusters encounter the obstructers, the clusters are broken to reduce their size and to loosen and separate soil from the rhizomes. A collector aft of the live bottom collects rhizomes falling from an aft end of the inclined ramp.

A fastener for a rod belt having one or more rods includes a support area, at least one intermediate area, and a fastening area. The support area extends in a longitudinal direction and includes a support side. The at least one intermediate area and the support area are made as one piece. The fastening area projects away from the intermediate area in the longitudinal direction.

Apparatus for cleaning narrow root crops including a roller device with two rotatable rollers forming a separating crop inlet, a separating track, a coarse material outlet, a fine material outlet, and a roller gap, and a conveyor downstream of the roller device. The separating track is formed by the top of the rollers and the fine material outlet is located below the roller gap. The coarse material outlet is at the end of the separating track opposite the separating material inlet. The roller gap is large enough to allow the narrow root crops to pass through to the fine crop outlet and small enough to retain coarse material that has a minimum dimension greater than the maximum root diameter, and transport it to the coarse material outlet. The conveyor is below the roller gap at the fine material outlet and receives all narrow root crops passing through the roller gap.
