ABSTRACT:
A hydrostatic drive vehicle includes an articulated frame formed by forward and rearward transmission cases which are pivotally joined. A first set of wheels is rotatably mounted to the forward transmission case, while a second set of wheels is rotatably mounted to the rearward transmission case. A first hydraulic motor is coupled to the first set of wheels by a chain reduction linkage and limited slip differential which are mounted within the forward transmission case. A second hydraulic motor is coupled to the second set of wheels by a chain reduction linkage and limited slip differential mounted within the rearward transmission case. An engine and hydraulic pump are mounted to the frame. The first and second hydraulic motors are coupled to the hydraulic pump in a series hydraulic circuit.
