Abstract: A vehicle includes a chassis, a first actuator coupled to the chassis, a second actuator coupled to the chassis, a third actuator coupled to the chassis, a fourth actuator coupled to the chassis, and a fluid circuit. The fluid circuit is configured to facilitate selectively fluidly coupling the first actuator, the second actuator, the third actuator, and the fourth actuator in a plurality of different configuration. In each of the plurality of different configurations, two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly coupled together while the other two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly decoupled.

Abstract: A lift device includes a chassis, a first actuator coupled to the chassis, a second actuator coupled to the chassis, a third actuator coupled to the chassis, a fourth actuator coupled to the chassis, and a fluid circuit. The fluid circuit is configured to facilitate selectively fluidly coupling the first actuator, the second actuator, the third actuator, and the fourth actuator in at least four different configurations where, in each of the at least four different configurations, two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly coupled together while the other two of the first actuator, the second actuator, the third actuator, and the fourth actuator are fluidly decoupled.
