Axle driving system

An axle driving apparatus comprising:

• an axle casing including an upper casing joined to a lower casing forming a first junction surface which lies in a first plane;
• an axle disposed within said axle casing;
• a center section disposed within said axle casing, said center section including a pump mounting surface and a motor mounting surface, said pump mounting surface being perpendicular to said motor mounting surface and lying in a second plane parallel to said first plane and offset therefrom by a distance t, said center section forming a second junction surface with said axle casing;
• a hydraulic pump disposed within said axle casing on said pump mounting surface;
• a hydraulic motor disposed within said axle casing on said motor mounting surface, said motor drivingly connected to said axle;
• and
• a mounting seat for said center section disposed within said casing which includes an extension having a length which is substantially aligned with said second junction surface.
