A vehicle includes an internal combustion engine (214), a first hydraulic pump/motor (218A) coupled with the internal combustion engine, and a second hydraulic pump/motor (218B) coupled with at least one driven wheel of the vehicle. A clutch (246) establishes a driving connection between the first hydraulic pump/motor and the internal combustion engine, and selectively interrupts the driving connection when disengaged. At least one vehicle accessory device (236B) is coupled to the first hydraulic pump/motor (218A). The at least one vehicle accessory device (236B) is operable under power of the internal combustion engine (214) when the clutch is engaged and the internal combustion engine is running, and the at least one vehicle accessory device is operable directly by the first hydraulic pump/motor (218A) operating in a motor mode when the clutch is disengaged, regardless of whether or not the internal combustion engine is running. In addition, a third hydraulic pump/motor (218C) is provided. A corresponding method of operating the vehicle is also provided. |
