ABSTRACT:
An amphibious, all-terrain vehicle utilizing a pair of hydrostatic pumps to independently provide power to hydraulic drive mechanisms of the left and right side of the vehicle respectively. The hydraulic drive mechanisms on a side of the vehicle comprise a plurality of hydraulic wheel motors and a hydraulic propeller motor. Using a novel hydraulic manifold assembly, the vehicle can operate in three distinct modes: wheels only, wheels and propellers, and propellers only. The hydraulic manifold assembly also allow the vehicle to by put in neutral mode for starting. The wheel motors are mounted in a pair of undercarriage assemblies that are outside of the vehicle's body and fluidly connected to the hydraulic manifold assembly thorough a hose chase that extends well above the vehicle's waterline to eliminate the potential for water to enter the body of the vehicle when operated in the water.
