1. A track system for a vehicle having at least three axles, the track system comprising:
a frame;
a sprocket wheel assembly being operatively connectable to a first axle of the at least three axles, a sprocket wheel being rotationally connectable to the frame;
an idler wheel assembly being rotationally connectable to the frame;
a plurality of support wheel assemblies being rotationally connectable to the frame;
a pivoting assembly having:
a casing operatively connectable to a second axle of the at least three axles,
at least one pivotable member having a first portion being pivotally connected to the casing, and a second portion being pivotally connected to the frame, the at least one pivotable member being pivotable between a first position and a second position about a longitudinally extending pivot axis causing the first portion to be displaced laterally relative to the second portion in response to the at least one pivotable member pivoting between the first position and the second position, and the at least one pivotable member being further pivotable between a third position and a fourth position about a laterally extending pivot axis causing the first portion to be displaced longitudinally relative to the second portion in response to the at least one pivotable member pivoting between the third position and the fourth position,
wherein the casing defines a laterally extending casing axis, the casing axis remaining parallel to the laterally extending pivot axis in response to the at least one pivotable member pivoting from the first position to the second position; and
an endless track wrapped around the sprocket wheel assembly, the idler wheel assembly and the plurality of support wheel assemblies.
