The present invention relates to automatic and high throughput smart, robotic, autonomous or driver operated, self-propelled field crops harvester (SPFCH) device of row crops, characterized by the need of selecting harvesting ripen crop, during relative long period of time. Harvesting is done by one or more modular robotic harvesting arms hanged on modular booms. When harvesting orchards fruits the SPFCH comprise at least one hybrid robotic arms equipped with a grabbing hand aimed to grab one or more fruit of a an adjacent fruits and also cut its connecting stem, and arm transporting mechanism that gently collects the fruits and transport them to the SPFCH main accumulation area. When harvesting cotton, the SPFCH of the invention may further comprise vacuum sucking hoses and at least one ginning unit that gin the seed-cotton during harvesting and accumulate the seeds in a self-container, and the lint by bales processed, on board by self-press.

A cotton harvester estimates the mass of cotton as it is harvested using sensor devices and compares the mass of each module against the estimated mass of the module as determined by the sensors so that a calibration factor may be determined and actively updated for more accurate crop yield determination. The mass flow for a specific module is accumulated and processed during harvesting using a base calibration factor and the module is weighed and compared against the expected mass using the base calibration factor to develop a candidate updated calibration factor. The base calibration factor is selectively replaced by the candidate updated calibration factor for processing a subsequent module based on machine feedback information relating to the operation of the harvester. Harvested crop data determined using the calibration factor is used to generate highly accurate yield maps.

A doffer assembly for a cotton harvester having at least one drum and a spindle. The doffer assembly includes an outer housing and a plurality of doffers adapted to remove cotton from the spindle. The assembly further includes a drive unit coupled to the outer housing for rotatably driving the plurality of doffers independently of at least one drum and spindle. A drive shaft is rotatably driven by the drive unit, and an interface adapter is coupled between the drive shaft and the plurality of doffers. The drive unit may be an electric motor, hydraulic motor, a mechanical drive system, or a combination thereof.

A sensor input is detected on a cotton harvester. A performance characteristic value is identified based upon the detected sensor input. A speed control system controls cotton harvester drum speed and spindle speed, automatically, and separately from the ground speed of the cotton harvester, to improve the performance characteristic value, in a closed-loop fashion.

Roll assemblies for cotton harvesters and associated methods are disclosed. Example roll assemblies may include a unitary component that defines a plurality of slots. Bats and brushes may be removably retained within the slots. The unitary component may include a plurality of lobes with the plurality of slots defined therebetween. A central passage may be formed in a central portion of the unitary component. A shaft having an interlocking shape may be removably received within the central passage. In some implementations, one or more lobes are removably securable to the unitary component. End caps may be received onto the shaft and positioned adjacent to ends of the unitary component to assist in retaining the bats and brushes to the unitary component.

An agricultural vehicle is operable in a first state for transport and in a second state for field work and includes a frame supported by a plurality of tires. A processor is operable to receive a signal generated as a result of the agricultural vehicle transitioning from the first state to the second state or from the second state to the first state. A gas system is operable to modify the tire pressure of the plurality of tires of the agricultural vehicle in response to the signal.

An agricultural vehicle for picking or harvesting a product includes a motor, a plurality of tires, a transmission mating the motor to the plurality of tires, an accumulator operable to store the product, a module builder operable to receive the product from the accumulator, and a frame supporting the accumulator and the module builder. The frame defines a hatch through which an operator is capable of accessing the motor and/or the transmission. The agricultural vehicle is operable to transition between a first state and a second state. In the first state, the module builder and the accumulator prohibit access through the hatch. In the second state, the module builder and the accumulator are rotated relative to the frame and provide access through the hatch.

A cotton doffer structure for doffing cotton snagged on a surface having debris. The cotton doffer structure comprises a plurality of single-piece extrusions cooperating to provide a rim. The rim has a longitudinal axis and a periphery with radial protrusions integrally extending outward from the periphery. A shaft is coupled to the rim for rotation therewith about the longitudinal axis in a forward direction and surrounded by the rim. Brushes are provided. Each brush has a base end supporting upstanding bristles, an opposing distal end, a leading side generally facing the forward direction, and an opposing trailing side. Each support member is provided that has a leading end and a trailing end with an upright flange. The brush support member secures a responsive one of the base ends of the plurality of brushes against a respective one of the radial protrusions with the upright flange located adjacent the leading side.
