A utility vehicle is shown for towing and servicing aircraft. The vehicle includes a frame and at least one tow hitch attached to the frame for towing an aircraft. An internal combustion engine is mounted on the frame within an enclosed interior and is connected by a power train to a pair of drive wheels for powering the vehicle. A heat recovery system within the enclosed interior receives warmed cooling air from the engine and products of combustion from the engine exhaust to route heated air to a flexible duct. The flexible duct is connected to an aircraft engine to be serviced in order to preheat the engine. The drive train of the vehicle includes a hydrostatic transmission and a differential gear box connected to the drive wheel axles. The hydrostatic transmission includes a self-centering servo mechanism for controlling the rate of speed change of the vehicle to prevent jerking an aircraft. Additional accessories are located on the vehicle which provide mobile servicing capability for servicing a variety of aircraft needs.
