1. A hydraulic apparatus for use in connection with a vehicle having a prime mover, comprising: a hydraulic pump assembly, comprising: a first pump driven by a first pump shaft; anda second pump driven by a second pump shaft;wherein the first pump shaft and the second pump shaft are driven by the prime mover;a pair of hydraulic motors, each hydraulic motor being hydraulically connected to one of the pumps; anda subframe for mounting the hydraulic pump assembly and the pair of hydraulic motors, the subframe comprising: a first vertical subframe member attached to one of the pair of hydraulic motors;a second vertical subframe member attached to the other of the pair of hydraulic motors; anda horizontal subframe member extending from the first vertical subframe member to the second vertical subframe member, wherein the horizontal subframe member forms a generally flat mounting surface for the prime mover;a stabilizer bar extending from one of the pair of hydraulic motors to the other of the pair of hydraulic motors; anda plurality of attachment points for securing the pair of hydraulic motors and the prime mover to the subframe. 2. The hydraulic apparatus of claim 1, wherein each of the hydraulic motors comprises a motor shaft, and the subframe positions the pair of hydraulic motors so that the motor shafts are generally collinear with each other. 3. The hydraulic apparatus of claim 1, wherein the horizontal subframe member comprises an opening for a vertical output shaft of the prime mover. 4. The hydraulic apparatus of claim 1, wherein the first pump shaft and the second pump shaft are driven by the prime mover via one or more pulleys. 5. The hydraulic apparatus of claim 4, wherein the one or more pulleys are connected to a vertical output shaft of the prime mover. 6. The hydraulic apparatus of claim 1, wherein: the prime mover is attached to the horizontal subframe member using one or more first fasteners each through a respective one of the plurality of attachment points;one of the pair of hydraulic motors is attached to the first vertical subframe member using one or more second fasteners each through a respective one of the plurality of attachment points; andthe other of the pair of hydraulic motors is attached to the second vertical subframe member using one or more third fasteners each through a respective one of the plurality of attachment points. 7. A vehicle, comprising: a prime mover;first and second hydraulic pumps, the first and second pumps each driven by the prime mover;a pair of hydraulic motors, each hydraulic motor being hydraulically connected to one of the pumps; anda subframe for mounting the first and second pumps and the pair of hydraulic motors, the subframe comprising: a first vertical subframe member attached to one of the pair of hydraulic motors;a second vertical subframe member attached to the other of the pair of hydraulic motors; anda horizontal subframe member extending from the first vertical subframe member to the second vertical subframe member, wherein the horizontal subframe member forms a generally flat mounting surface for the prime mover;a stabilizer bar extending from the first vertical subframe member to the second vertical subframe member, and further extending from one of the pair of hydraulic motors to the other of the pair of hydraulic motors; anda plurality of attachment points for securing the pair of hydraulic motors and the prime mover to the subframe. 8. The vehicle of claim 7, wherein: the first pump is driven by a first pump shaft;the second pump is driven by a second pump shaft; andthe first pump shaft and the second pump shaft are driven by the prime mover. 9. The vehicle of claim 8, wherein the first pump shaft and the second pump shaft are driven by the prime mover via one or more pulleys. 10. The vehicle of claim 9, wherein the one or more pulleys are connected to a vertical output shaft of the prime mover. 11. The vehicle of claim 7, wherein each end of the stabilizer bar is located proximate to one of the pair of hydraulic motors. 12. The vehicle of claim 7, wherein each of the hydraulic motors comprises a motor shaft, and the subframe positions the pair of hydraulic motors so that the motor shafts are generally collinear with each other. 13. The vehicle of claim 7, wherein the horizontal subframe member comprises an opening for a vertical output shaft of the prime mover. 14. The vehicle of claim 7, wherein: the prime mover is attached to the horizontal subframe member using one or more first fasteners each through a respective one of the plurality of attachment points;one of the pair of hydraulic motors is attached to the first vertical subframe member using one or more second fasteners each through a respective one of the plurality of attachment points; andthe other of the pair of hydraulic motors is attached to the second vertical subframe member using one or more third fasteners each through a respective one of the plurality of attachment points.
