A shaft is coupled to the extrusion for rotation therewith about the longitudinal axis in a forward direction. A plurality of 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. A plurality of brush support members are provided that have a leading end and a trailing end with an upright flange. The plurality of brush support members securing the base ends of the plurality of brushes against the protrusion with the upright flange located adjacent the leading side.

A method of monitoring a material yield sensor assembly for upward baseline drift, the method comprising steps of receiving a signal representing a plurality of raw baseline datapoints from the material yield sensor assembly, passing the raw baseline datapoints through an IIR filter thereby producing a plurality of filtered datapoints, fitting the filtered datapoints to a curve via a curve fitter thereby producing a plurality of fitted datapoints, and generating an alarm indicating the material yield sensor assembly should be serviced if a fitted datapoint of the plurality of fitted datapoints is greater than a first threshold.

A material yield sensor assembly comprising a photodiode and a processing element. The photodiode is configured to generate a signal representative of an amount of material passing by the photodiode. The processing element is configured to convert the signal from an analog form to a digital form, determine a clipping density of the signal, decrease a gain of the signal if the clipping density is greater than a first threshold, and increase the gain of the signal if the clipping density is less than a second threshold to optimize signal integrity versus signal resolution.

One or more techniques and/or systems are disclosed for a harvester vehicle that includes a crop processing system comprising at least an accumulator and a round module builder. The harvester vehicle has a feedback fusion system that operably provides crop processing data indicative of an estimated accumulator fill level to a crop feed rate control system. The feedback fusion system has a plurality of feedback devices that operably provide feedback signals including data indicative of two or more of: crop mass flow, module builder status, module size, and accumulator fill level. The feedback fusion system has a control module that operably receives the feedback signals and generates an accumulator fill level signal based at least upon two or more of the feedback signals. The accumulator fill level signal is indicative of the estimated fill level in the accumulator.

The present invention relates to a cutter (1) for a base cut assembly (11) applied to a sugar-cane harvesting machine (100). The base cut assembly (11) comprises a support rod (2), which is provided with a substantially C-shaped geometric profile, this support rod (2) being associated to an axle (3) of the base cut assembly (1) simultaneously in its first portion and second portion (21; 29).

In one aspect, a cotton harvester includes a harvesting implement configured to harvest materials from a field. The harvested materials include both cotton and material other than cotton (MOC). The harvester also includes a material processing system configured to receive the harvested materials from the harvesting implement, with the harvested materials being directed through the material processing system along a material transfer path. Additionally, the harvester includes a sensor configured to generate data indicative of an amount of MOC contained within the harvested materials at a location along the material transfer path, and a computing system communicatively coupled to the sensor. The computing system is configured to adjust an operational setting of the cotton harvester based at least in part on the amount of MOC contained within the harvested materials.

A linkage assembly of an agricultural harvester includes a rigid lower link, a bendable top link, a linear actuator, and a stop. The rigid lower link, bendable top link, and linear actuator are configured to pivotally connect to a drum toolbar and to a harvester frame. The stop is configured to couple to the harvester frame, and the bendable top link is configured to bend in response to engagement with the stop to pitch the drum toolbar relative to the harvester frame. The linear actuator is configured to extend and retract to lift and lower the drum toolbar.

Disclosed are an array cutting knife-type cotton topping machine and a control method thereof. The cotton topping machine includes cameras, controllers, a tacho-generator and a plurality of groups of topping assemblies arranged in a left-right direction; the cameras and the tacho-generator are connected to the controllers; and a plurality of topping devices staggered left and right are arranged for each planting row. In the present disclosure, by densely arranging low-cost topping devices and determining which topping devices are switched to an operating state for topping according to visually determined top bud positions, the potential problems in the prior art of the damage to other parts of the plant or the unnecessary intertwining of branches and leaves are avoided.

An electrohydraulic system for a work machine includes a pump, a motor fluidly coupled to the pump, a subassembly driven by the motor, and a rate-control valve fluidly coupled to the pump and the motor. The rate-control valve is movable through a range of positions. A present speed of the motor is proportional to a present position of the rate-control valve. The present position of the rate-control valve is adjustable by varying a current supplied to the rate-control valve. The supply of current to the rate-control valve is adjusted based on the difference between the present speed of the motor and a target speed of the motor.
