1. A machine, comprising:
a frame;
an oscillating hitch configured to pivot relative to the frame;
a first cylinder coupled to a first side of the oscillating hitch and a first side of the frame;
a second cylinder coupled to a second side of the oscillating hitch and a second side of the frame;
a first isolating mechanism coupled to the first cylinder and configured to rotate in response to a first rotation of the first cylinder relative to at least one of the frame or the oscillating hitch, the first isolating mechanism including first prongs that engage an exterior surface of the first cylinder to couple the first isolating mechanism to the first cylinder;
a first angle sensor configured to sense a first angular displacement of the first isolating mechanism about a first rotational axis;
a second isolating mechanism coupled to the second cylinder and configured to rotate in response to a second rotation of the second cylinder relative to at least one of the frame or the oscillating hitch, the second isolating mechanism including second prongs that engage an exterior surface of the second cylinder to couple the second isolating mechanism to the second cylinder; and
a second angle sensor configured to sense a second angular displacement of the second isolating mechanism about a second rotational axis.
