Abstract: 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.

Abstract: A hydraulic power module for a crop harvester, and in particular a cotton harvester, having an engine. The hydraulic power module includes a main drive gear, a drive shaft extending through the main drive gear, and a clutch operatively connected to the drive shaft, wherein the clutch has an engaged position and a disengaged position. The engaged position of the clutch fixedly connects the main drive gear to the drive shaft and the disengaged position of the clutch disconnects the main drive gear drive from the drive shaft. The hydraulic power module further includes a first pump device directly coupled to the drive shaft, wherein the first pump device is driven by the drive shaft during rotation of the drive shaft. A second pump device is indirectly connected to the drive shaft through the clutch, and is driven by the drive shaft when the clutch is in the engaged position.

Abstract: 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.

Abstract: A module builder of an agricultural vehicle includes a chamber operable to support and form a product. A wrap is feedable into the chamber through a pinch point, the pinch point partially defined by a rotatable roller. A belt at least partially defines a wrap path. The wrap is configured to move along the wrap path to surround the product in the chamber. A gas flow system and/or a reversing belt is operable to direct the wrap from the pinch point toward the wrap path.

Abstract: 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.
