Abstract: Disclosed is a three piece snowmobile dolly system that during use is secure in placement under a snowmobile and during nonuse may be compactly nested together. The dolly system is comprised of two forward ski dollies and a rearward track dolly. Each of the forward dollies have a planar base portion with two sidewalls for receiving one of the skis and a V-shaped depression in the planar base for receiving and engaging the wear bar on the bottom of the ski. The rearward dolly has a planar base with four castors for stability. The planar base portions with the sidewalls of the forward ski dollies mesh together and the rearward dolly nests intermediate the castors of either forward ski dolly resulting in a compact package for storage.
