Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. Thus the discarded seeds rebound back and forth between the rotor and the stator to provide a plurality of impacts. The seeds are carried axially of the rotor by a controlled airstream so that they move to an axial discharge location where a discharge fan is mounted. The angle of the discharge around the rotor axis can be changed to direct the seeds to the side of the combine away from a straw chopper, towards the guide fins of the tailboard of the chopper, or into the housing of the straw chopper.

An energy storage arrangement includes a shaft for transmitting torque, a housing, an actuator configured to be axially moved, a freewheel disposed between the shaft and actuator and fastened to the shaft, the freewheel being configured to transmit no torque in one rotational direction, an energy store configured to store torque, a support element, an outer coupling between the housing and the support element, and an inner coupling between the support element and the shaft.

A harvester is provided with a draper head that has a frame extending substantially across a working width of the draper head. Cutting elements are arranged at a front side of the draper head and connected to the frame. Conveying surfaces and conveying members transport cut crop from the cutting elements to a discharge location of the draper head. A reel extends transversely to a working direction of the draper head across the working width of the draper head. Reel support arms are pivotably supported on the frame and support the reel. A hydraulic adjusting drive is operatively connected to the reel support arms to pivot the reel support arms to carry out a height adjustment of the reel. A hydraulic circuit is operatively connected to the hydraulic adjusting drive and has a hydraulic valve that is able to lock the hydraulic circuit.

A tensioning bar assembly for a tensioning assembly of a drive system of an agricultural machine includes a longitudinal bar having a longitudinal axis, a top end, and a bottom end. An attachment device is attached to the top end of the longitudinal bar. A compression spring has first and second ends, and is located around a portion of the longitudinal bar. A first spring retainer engages with and retains the first end of the spring. The longitudinal bar has a bolt section, and the bolt section has a threaded portion, an engagement head, and a sleeve section. The sleeve section includes an internally threaded hollow section for receiving the bolt section. The sleeve section is fixed and rotationally attached to the attachment device.

Systems and methods for mechanical Cannabis harvesting which utilize a harvester having two counter-rotating rollers, each having a brush thereon, where the brushes serve to strip leaves and buds from the stalk of a standing Cannabis plant introduced to a harvesting space between them. The brushes transport the stripped leaves and buds to a series of conveyors that eventually deposit the leaves and buds in a hopper. The stripped stalk of the Cannabis plant may be left standing in the field to be cut down later, or may be knocked or cut down by the harvester.

A feederhouse assembly for an agricultural harvester includes a feederhouse comprising an inlet end, a rotational shaft coupled to the feederhouse and defining a plurality of fluid passages therethrough, and a frame adjacent the inlet end and arranged to pivot about the rotational shaft relative to the feederhouse. The frame defines a crop opening therethrough and is configured to carry a harvesting header. An agricultural harvester includes a chassis, the feederhouse assembly mounted to the chassis, and a processing system carried by the chassis and structured to receive crop material from the feederhouse.

Various embodiments of a grounds maintenance vehicle are disclosed. The vehicle includes a frame and a control tower disposed at or near a rear end of the frame. The control tower includes a support structure that defines an interior space of the control tower and a nonplanar removable skin connected to the support structure. The removable skin includes a front side disposed over a front side of the support structure and a lateral side disposed over at least one of a left side or a right side of the support structure. A portion of at least one of the front side or lateral side of the removable skin is disposed above an uppermost surface of the prime mover. Further, the removable skin is adapted to be at least partially removed from the support structure to facilitate additional access to the interior space of the control tower.
