ABSTRACT:
An amphibious vehicle has a body with front and rear portions, opposite sides and a bottom. The vehicle includes at least one pair of wheels, each wheel being located adjacent a respective side, and a wheel mounting structure for moving the respective wheel between raised and lowered positions thereof. Thus, when the wheels are in the raised position, lower portions of the wheels are raised above the bottom, providing clearance when the vehicle is used in water, and when in the lowered position thereof, the lower portions of the wheels are below the bottom to support the vehicle on a bearing surface. Preferably, the vehicle has two pairs of wheels, and each pair can be moved independently of the remaining pair. For some uses, the wheels of each pair could be moved independently of each other.
