Abstract
A backhoe arrangement is described wherein overcenter forward movement of the boom and boom cylinder provides a transport configuration for the backhoe, and the backhoe operator's view of the bucket is enhanced. A swing tower is attached to the rear of the machine and serves as a support that embraces an asymmetrically mounted or offset boom assembly wherein the longitudinal axis of the boom and the longitudinal axis of the hydraulic actuator operating the boom are offset from the vertical axis of rotation of the swing tower. The boom hydraulic actuator flanks the boom in a clearance relationship that permits the boom to assume a substantially vertically directed neutral intermediate position. An offset boom and actuator improves the center of gravity of the backhoe and allows the boom actuator to be protected by the boom.
