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.

A plant stalk stomper assembly is operable to be mounted relative to a toolbar of a row crop header for advancement over the ground in a forward travel direction. The stomper assembly includes a frame and an elongated stomper skid plate operable to engage the ground as the stomper assembly is advanced in the forward travel direction. The skid plate presents an attachment section along which the skid plate is mounted relative to the frame. At least part of the skid plate includes a unitary plate element that depends below the attachment section to present a lowermost ground-engaging margin. The unitary plate element includes a deformation region located between the attachment section and the ground-engaging margin, with the unitary plate element operable to bend along the deformation region in response to relative movement between the attachment section and the ground-engaging margin.

A yard maintenance device having a working assembly selectively rotatable based on operation of an engine of the device may include a belt drive system. The belt drive system may include at least one driven pulley operably coupled to the working assembly, a drive shaft operably coupled to the engine, a drive belt configured to selectively couple the drive shaft to the at least one driven pulley, a tension adjustment assembly, and a control unit. The tension adjustment assembly may be configured to operably couple to at least one component of the belt drive system to adjust a position thereof to modify tension of the drive belt. The control unit may be configured to provide electronic control of the tension adjustment assembly.

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.

A seed cotton dryer comprises an array of electromagnetic wave energy generators in a cotton gin, a cotton picker/stripper. An appropriate amount of energy is used to evaporate a considerable amount of moisture in the seed cotton without producing enough energy to pop the cotton seeds. Seed cotton dried by wave energy is much easier to separate the cotton seeds and lint from leaves, stems and other plant parts. The seed cotton is preferably transported through the dryer in a conduit having flat sides which reflects the wave energy more efficiently than through a round conduit. Provisions are made to prevent arcing in the transport conduit when extraneous metal pieces are inadvertently mixed with the seed cotton. In some embodiments, heated air from a diesel engine is used to dry crops as they are being harvested.

A stalk puller to be used with or without a mower/shredder utilizes a pair of independently mounted discs converging along their lower edge to grasp and pull stalks from the ground as the stalk puller is moved down the row by a prime mover. At least one of the discs is urged against the other by a spring such that the associated disc may allow rocks and debris to pass between the discs without damage. The spring mounting reduces adjustments due to normal wear as well as damage from debris.
