Vehicle with adjustable hitch

A vehicle comprising:

• a frame;
• a first hitch coupled to a first end of the frame;
• a first cylinder positioned to move the first hitch relative to the frame, the first cylinder having a first chamber that increases in volume when the first hitch is lowered;
• a second hitch coupled to a second end of the frame opposite the first end;
• a second cylinder positioned to move the second hitch relative to the frame, the second cylinder having a second chamber that increases in volume when the second hitch is lowered;
• and
• a fluid system fluidly coupled to the first cylinder and the second cylinder, the fluid system including:
• a first action select valve reconfigurable between (a) a single-acting configuration in which the first action select valve drains a fluid from the first chamber to a low-pressure return while the first hitch is lowered and (b) a double-acting configuration in which the first action select valve supplies the fluid to the first chamber while the first hitch is lowered;
• and
• a second action select valve reconfigurable between (a) a single-acting configuration in which the second action select valve drains the fluid from the second chamber to the low-pressure return while the second hitch is lowered and (b) a double-acting configuration in which the second action select valve supplies the fluid to the second chamber while the second hitch is lowered.

• a fluid system fluidly coupled to the cylinder, the fluid system including:
• a pressure supply;
• a low-pressure return;
• an action select valve including a port, wherein in a double-acting configuration, the action select valve fluidly couples the second chamber to the port, and wherein in a single-acting configuration, the action select valve fluidly couples the second chamber to the low-pressure return;
• and
• a mode valve reconfigurable between a raise configuration and a lower configuration,
• wherein in the raise configuration, the mode valve (a) fluidly couples the pressure supply to the port and (b) fluidly couples the first chamber to the low-pressure return;
• and
• wherein in the lower configuration, the mode valve (a) fluidly couples the port to the low-pressure return and (b) fluidly couples the pressure supply to the first chamber.
