Abstract: A machine includes a frame and an oscillating hitch. A first cylinder couples to a first side of the oscillating hitch and a first side of the frame. A second cylinder couples to a second side of the oscillating hitch and a second side of the frame. A first isolating mechanism couples to the first cylinder and rotates in response to a first rotation of the first cylinder relative to the frame or the oscillating hitch. A first angle sensor senses a first angular displacement of the first isolating mechanism about a first rotational axis. A second isolating mechanism couples to the second cylinder and rotates in response to a second rotation of the second cylinder relative to the frame or the oscillating hitch. A second angle sensor senses a second angular displacement of the second isolating mechanism about a second rotational axis.

Abstract: A control system for a machine having a linkage, a work implement mounted on the linkage, and at least one actuator is provided. The actuator is connected to the linkage and controlled using the control system to move the linkage and the work implement. The control system includes sensors that are configured to sense a current load and position of the work implement. Upon sensing the current load and position of the work implement, a controller provided in the control system can reject or accept a given kick-out command issued from one or more user controls of the control system based on various criteria associated with the sensed load and position of the work implement.

Abstract: A machine includes a frame, a first steering arm, a second steering arm, a first hydraulic actuator coupled to the frame and the first steering arm, and a second hydraulic actuator coupled to the frame and the second steering arm. A first angle sensor measures a rotational displacement of the first hydraulic actuator relative to the first steering arm. A first link couples the first hydraulic actuator and the first sensor, and isolates movements other than the first rotational displacement. A second angle sensor measures a second rotational displacement of the second hydraulic actuator relative to the second steering arm. A second link couples the second hydraulic actuator and the second sensor, and isolates movements other than the second rotational displacement.
