Backhoe-style boom

A backhoe apparatus with a boom structure which is movable overcenter in a fore-and-aft direction and a boom actuator arranged in fore-and-aft alignment with and protected by lateral sides of the boom structure. A swing tower is connected about a lower pivot axis to a lower end of the boom and allows for lateral swinging movement of the boom. The swing tower allows for overcenter movement of the boom to opposite sides of an upper pivot axis on the swing tower whereat one end of the boom actuator is secured. The boom structure has a curved configuration at its lower end to accommodate nesting of the boom actuator while maintaining torsional rigidity for the boom.

Overcenter backhoe apparatus

An improved swingable tractor-backhoe interconnection for a tractor-mounted backhoe having a pair of vertically-spaced articulation means along the axis forming an axially-aligned void space therebetween, a preferably free-floating center yoke in the void space with two vertical rows of openings securing hydraulic hoses in two adjacent rows, and a pair of side yokes on the tractor, one for each row of hoses, positioned on opposite sides of the center plane and spaced from the axis and center plane such that the two rows of hoses are divergent between the center and side yokes.
