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 first pivot extending vertically and defining a yaw pivot axis of the track system, the first pivot being defined by a cylindrical projection suitable for being received in an axle casing of the attachment system and a base of the attachment system, and
a second pivot extending laterally and defining a pitch pivot axis of the track system, the second pivot extends through at least one tab defined in the base,
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;
at least one actuator connected between the attachment assembly and the frame assembly for pivoting the frame assembly about the yaw pivot axis;
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; and
a sprocket wheel operatively connectable to the vehicle, the sprocket wheel defining a rotation axis;
wherein the second pivot is disposed below the axis of rotation defined by the sprocket wheel.
