    摘要: Hydraulic power savings for a rear module handler cylinder of a round module cotton harvester is possible by using a regenerative hydraulic arrangement for raising an empty handler and using gravity to lower the handler. A bale handler system for a cotton picker baler includes a handler for receiving a round module that is movable between upright and lowered positions and a handler cylinder operably connected to the handler. The handler cylinder system includes a regenerative valve. The regenerative valve is engaged when the handler moves to the upright position during regenerative handler raise mode of operation, the regenerative valve is not engaged when the handler moves to the lowered position during float handler lower mode of operation. While in the float handler lower mode of operation, the handler cylinder retracts and diverts an oil flow pressure from a base end to a rod end of the handler cylinder.

    摘要: Systems for harvesting machines, transmissions for harvesting machines, and methods of operating systems for harvesting machines are disclosed herein. A system includes a drive unit, a cleaner unit, an aspirator, and a transmission. The drive unit is configured to produce rotational power in use of the system. The cleaner unit is fluidly coupled to the drive unit and configured to separate debris from air so that the air becomes cleaned air and provide the cleaned air to the drive unit in use of the system. The aspirator is fluidly coupled to the cleaner unit and configured to draw debris away from the cleaner unit and exhaust the debris in use of the system. The transmission is coupled to the drive unit and the aspirator.

    摘要: A cotton harvester having a prime mover providing power to the cotton harvester, a controller monitoring a load on the prime mover and storing a load threshold, a drum rotatable about a first axis at a drum speed, a plurality of spindles for harvesting cotton, the plurality of spindles rotatable at a spindle speed and a doffer assembly rotatable about a second axis at a doffer speed. Wherein, when the controller detects a load on the prime mover greater than the load threshold, the spindle speed is reduced.

    摘要: A cotton harvester with a hydraulic manifold and at least one hydraulic motor mechanically coupled to a drum and fluidly coupled to the hydraulic manifold, the hydraulic motor configured to selectively rotate the drum. Wherein, the hydraulic manifold is configured to selectively provide any one of a braking force and a torque to the drum through the at least one hydraulic motor.

    摘要: 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.
