Abstract: A lightweight snow groomer designed to be towed behind a snowmobile, ATV, or UTV with an adjustable v-plow. The snow groomer includes multiple links pivotably connected to its drawbar assembly and the plow that allow the plow to swing upwardly and rearwardly under the drawbars. The snow groomer preferably includes a front link adjacent to its coupler for leveling the plow/pan assembly and for vertical adjustment to accommodate different hitch heights. The snow groomer also ideally has a lift assembly with a threaded arm that screws up and down the lift assembly. The linkage may include a slotted link segment that pivotably connects to the plow and allows the plow to float on compacted snow or leave the desired amount of snow, depending on the adjustment, for compacting. The preferred v-plow can swing upwardly and rearwardly when striking obstacles during operation of the snow groomer.
