ABSTRACT:
A vehicle base subassembly with a base frame comprising a pair of spaced apart side rails joined by spaced apart torque tubes with the torque tubes centered about the drive axes of the subassembly. A prime mover module is slidably mounted in the base frame with an internal combustion engine driving a pair of hydraulic pumps. A hydraulic drive motor is carried by opposite ends of each of the torque tubes with the motors on one side of the subassembly operated in tandum and independently from the motors on the other side. A wheel and tire assembly is carried by each drive motor and the output of the hydraulic pumps is controlled to operate the subassembly according to the skid-steer principle. A mounting platform for accessory equipment is provided on the base subassembly to accept different pieces of accessory equipment.
