Abstract
A bale chamber includes: movable density doors; at least one fluid cylinder including a fluid chamber, a piston separating 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 fluid supply circuit including 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 when in the first fluid supply mode and to supply working fluid to both the piston side and the rod side when in the second fluid supply mode.
