Abstract
Abstract A recreation vehicle for rough terrain cross-country travel by one or two passengers includes a forward tracked pulling unit and a rear wheeled power unit which is steerable from the forward unit. Additional controls on the forward unit effect braking of the rear wheeled unit and raising and lowering of the forward unit to vary the degree of contact of the endless track means with the ground. The vehicle may be converted to water travel and may be used on snow.
