Agricultural baler with density doors moved by dual acting fluid cylinders

An agricultural vehicle, comprising:

• a chassis;
• and
• a bale chamber carried by the chassis, the bale chamber comprising:
• a plurality of movable density doors;
• at least one fluid cylinder comprising a fluid chamber, a piston disposed in the fluid chamber to separate the fluid chamber into a piston side and a rod side, a cylinder rod coupled to the piston on the rod side and configured to move at least one of the density doors, a piston fluid port, and a rod fluid port;
• and
• a fluid supply circuit fluidly coupled to the fluid chamber and configured to supply working fluid to the fluid chamber, the piston fluid port fluidly coupling the piston side of the fluid chamber to the fluid supply circuit and the rod fluid port fluidly coupling the rod side of the fluid chamber to the fluid supply circuit, the fluid supply circuit comprising a fluid supply controller that is selectively switchable to a first fluid supply mode and a second fluid supply mode, the fluid supply circuit being configured to supply working fluid to only the piston side of the fluid chamber when the fluid supply controller is in the first fluid supply mode and to supply working fluid to both the piston side and the rod side of the fluid chamber when the fluid supply controller is in the second fluid supply mode.
