Assignee: DEERE & COMPANY
Field: Other special machines (Mechanical engineering)
Classification: CPC A  F | IPC A  F

Claim 7:
8. An agricultural machine, comprising:
a frame;
a harvesting header coupled to the frame, the harvesting header configured to remove crop from a field;
a module builder for receiving the crop and forming a bale of crop;
a bale handler system coupled to the frame and being movable between a raised position where the bale handler system receives the bale of crop from the module builder and a lowered position, the bale handler system comprising a handler cylinder having a base end and a rod end; and
a control valve block for hydraulically controlling the handler cylinder between an extended position and a retracted position, the control valve block comprising a first solenoid valve, a second solenoid valve, a third solenoid valve, a regenerative valve, and a first check valve;
wherein, the first check valve and a second check valve are fluidly coupled between the regenerative valve and the base end of the handler cylinder;
wherein, when moving the bale handler system to the raised position, the handler cylinder is extended by providing hydraulic fluid from a pump through the third solenoid valve to the base end of the cylinder, and redirecting hydraulic fluid flows along a flow path from the rod end through the regenerative valve, the first check valve, and the second check valve to the base end.
