Synchronous belt systems include two or more sprockets, a first endless belt, and a second endless belt. The belts are connected together with belts attachment hardware through belt ports, and a belts gap is defined between the belts. Each of the sprockets includes sprocket teeth and sprocket tooth spaces between adjacent teeth of the sprocket teeth, and each of the sprockets has a sprocket center ridge. The belts each include a plurality of belt teeth which engage sprocket tooth spaces. The belts gap engages the sprocket center ridge of each of the sprockets. Each of the belts attachment hardware includes a connecting bar which renders a parallel and adjacent configuration of the first endless belt and the second endless belt.

An arrangement for controlling the operation of a draper belt header of a combine harvester includes a central belt conveyor of the draper belt header having a drive for operably driving the conveyor and two outer belt conveyors attached to a feeder house of the combine harvester. The feeder house has a controllable height which may be controllably adjusted by an actuator. The arrangement further includes a control unit operable to stop the drive of the central belt conveyor or move it into a reversing mode if the feeder house is being raised by the actuator.

A shaker mechanism used in an agricultural machine, such as sugarcane harvesters and sweet sorghum harvesters. The shaker mechanism is configured for removing mud, dirt and plant remains accumulated in a lower protective tarpaulin of a mounting chassis of conveyor rollers and choppers of the agricultural machine. The shaker mechanism includes at least a bar having ends which are fastened on rotary support bearings. The bar is configured to stand at least partially out from an edge of the bearings forming at least a spare surface for contact with a protective tarpaulin positioned on the chassis of the machine.

A flexible and rotatable coupling assembly for a feeder conveyor of a combine harvester, for example. The coupling assembly connects a first rotatable shaft to a second rotatable shaft. The coupling assembly includes a spherical bearing that is connectable to the first rotatable shaft for accommodating a radial or angular misalignment between the first and second rotatable shafts; and a flexible and rotatable coupler that is non-rotatably connectable to the first and second rotatable shafts for transferring rotation between the first and second rotatable shafts. The flexible and rotatable coupler is either directly or indirectly connected to the spherical bearing. The flexible and rotatable coupler has a flexible component for accommodating the radial or angular misalignment.

A conveyor device includes a first axis equipped with at least two first pulleys rotating coaxially around a first rotation axis and spaced apart, a second axis provided with at least two second pulleys coaxially rotating around a second rotation axis and spaced apart, wherein each first pulley is aligned with a corresponding second pulley along a movement direction of the conveyor device. A conveyor belt extends between the first and the second axis and is wrapped around said first and second pulleys. Said conveyor belt includes a substantially flat base body made of rubberized cloth and having a first face, a second face and a traction body made in one piece with its lateral zone, projecting from the first face and couplable to a first pulley and to the respective second pulley for moving the conveyor belt, and a plurality of cross bars extending transversely to said movement direction between the lateral zones.

An agricultural vehicle header having a frame, at least one support arm extending, a cutter assembly attached to the distal ends of the support arms, a draper belt with an upper belt portion located above the support arms, and a parallel linkage connected to each support arm to operatively connect the cutter assembly to the frame. The linkage includes upper and lower links. The upper belt portion extends along a cross-belt direction that is perpendicular to a travel direction of the upper belt portion, and the proximal pivots of the upper and lower links are positioned on a line that is oriented at an angle of 60 to 120 degrees relative to the cross-belt direction when the header is in a freestanding static state.
