The snow groomer may comprise a chassis, an operator cabin mounted to the chassis from which operation of the snow groomer is controlled, track assemblies for causing the snow groomer to advance, a power plant in a driving relationship with the track assemblies, and a tiller assembly attached at the rear of the chassis. The operator cabin comprises a seating system that includes an operator seat, a base, and a seat carriage mounted to the base, which allows the operator seat both to move in a direction transverse to the direction of motion of the snow groomer, and to pivot about an axis.
