Hydraulic regeneration system

A method of moving a work implement actuated by a first hydraulic actuator having a first chamber and a second chamber and a second hydraulic actuator having a third chamber and a fourth chamber, comprising:

• directing a flow of fluid through a first directional control valve to the first chamber of the first hydraulic actuator and the third chamber of the second hydraulic actuator to move the work implement in a first direction;
• directing a flow of fluid through a second directional control valve to the second chamber of the first hydraulic actuator and the fourth chamber of the second hydraulic actuator to move the work implement in a second direction;
• and
• directing fluid released from at least one of the first, second, third, and fourth chambers through a third directional control valve into at least one of a fifth and a sixth chamber of a third hydraulic actuator.

A hydraulic system, comprising:

• an accumulator;
• a source of pressurized fluid;
• a first directional control valve;
• a second directional control valve;
• a first fluid line connecting the source of pressurized fluid with the first directional control valve;
• a second fluid line connecting the source of pressurized fluid with the second directional control valve;
• and
• a third directional control valve configured to control the rate and direction of fluid flow between the accumulator and the first and second fluid lines.

A method of using pressurized fluid stored in a hydraulic circuit having a source of pressurized fluid and an accumulator, comprising:

• connecting the source of pressurized fluid to a first directional control valve with a first fluid line;
• connecting the source of pressurized fluid to a second directional control valve with a second fluid line;
• and
• directing a flow of pressurized fluid from the accumulator through a third directional control valve to one of the first and second fluid lines.

A work machine, comprising:

• a work implement;
• a first hydraulic actuator having a first chamber and a second chamber and operatively connected to the work implement;
• a second hydraulic actuator having a third chamber and a fourth chamber and operatively connected to the work implement, the second hydraulic actuator being capable of operating independently from the first hydraulic actuator;
• a source of pressurized fluid;
• a first directional control valve disposed between (i) the source of pressurized fluid and (ii) the first chamber of the first hydraulic actuator and the third chamber of the second hydraulic actuator;
• and
• a second directional control valve disposed between (i) the source of pressurized fluid and (ii) the second chamber of the first hydraulic actuator and the fourth chamber of the second hydraulic actuator.

A work machine, comprising:
