Swing Motor Mounting Arrangement Abstract Swing motors employed on backhoes and like constructions vehicles are interconnected between a tractor frame and a mast frame to selectively rotate the mast frame relative to the tractor frame. In addition to posing assembly and disassembly problems, conventional mounting arrangements for swing motors of this type oftentimes subject various spline connections, pins, and bearings to undue wear. The swing motor mounting arrangement of this invention overcomes the above problems by providing a pair of first brackets for pivotally mounting a mast frame on a tractor frame and a pair of second brackets for securing opposite ends of a shaft of a swing motor to the mast frame. A housing of the swing motor is connected to the tractor frame whereby pressurization of the motor will rotate the shaft relative to the housing to selectively swing the mast frame relative to the tractor frame.
