ABSTRACT:
This is a swing-tower arrangement for coupling a back-hoe assembly to a tractor or the like. It features a rocker swingable in elevation on the swing tower. An actuator on the swing tower controls the position of the rocker, improving transport and control of the backhoe and making practical the adaptation of the arrangement to a wide range of tows. Detachable rockers are variously used to shift the backhoe assembly to transport and working positions and to tow and lift other types of subordinate machines. A power takeoff is mounted on the rocker.
