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.
