1. A track system for use with a vehicle having a chassis, the track system comprising:
an attachment assembly connectable to the chassis of the vehicle, the attachment assembly including a multi-pivot assembly having at least one of
a first pivot extending longitudinally and defining a roll pivot axis of the track system,
a second pivot extending laterally and defining a pitch pivot axis of the track system, and
a third pivot extending vertically and defining a yaw pivot axis of the track system;
a frame assembly disposed laterally outwardly from the attachment assembly and connected to the attachment assembly, the frame assembly including at least one wheel-bearing frame member;
a leading idler wheel assembly at least indirectly connected to the at least one wheel-bearing frame member;
a trailing idler wheel assembly at least indirectly connected to the at least one wheel-bearing frame member;
at least one support wheel assembly at least indirectly connected to the at least one wheel-bearing frame member and disposed between the leading idler wheel assembly and the trailing idler wheel assembly;
an endless track extending around the leading idler wheel assembly, the trailing idler wheel assembly, and the at least one support wheel assembly;
at least one actuator connected between the attachment assembly and the frame assembly for pivoting the frame assembly about at least one of the roll pivot axis and the yaw pivot axis;
at least one monitoring sensor for determining, at least indirectly, at least one of a state of the track system and a ground surface condition; and
a track system controller communicating with the at least one monitoring sensor for receiving a signal indicative of the at least one of the state of the track system and the ground surface condition, the track system controller being configured to connect to and to control the operation of the at least one actuator based on the at least one of the state of the track system and the ground surface condition.
