  • Patent number: 5503242
    Abstract: A propeller driven vehicle for traversing snow and ice covered terrain with improved steering response and stability. The vehicle has a motor driven propeller providing motive force to sustain forward motion of the vehicle regardless of terrain conditions. The vehicle rides on four skis which greatly enhance the stability of the vehicle and prevent the likelihood of tipping during sudden and severe turning. A parallelogram suspension system provides maximum contact between the skis and the terrain while allowing the skis to respond to vertical undulations in the terrain. A foot operated drag brake is mounted in the rear of the vehicle to decelerate the vehicle.
