A drive assembly for a vehicle including a power source, a hydraulic pump powered by the power source, and a motor assembly including a plurality of hydraulic motors that are operably coupled to the hydraulic pump and that include a first pair of hydraulic motors operably coupled to rear wheels of a vehicle associated with the drive assembly and a second pair of hydraulic motors operably coupled to front wheels of the vehicle. The drive assembly further includes a proportional flow control valve configured to control a swash flow through a bypass path formed to enable part of a total flow exiting the hydraulic pump to bypass one of the first pair of hydraulic motors or the second pair of hydraulic motors, and an ECU configured to control a position of the proportional flow control valve to provide differential speed control between the first and second pairs of hydraulic motors.
