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.
