A tool assembly mountable on the handle of a material working machine generally including a link mountable on the machine handle for pivotal movement about a first axis and connectable to a fluid actuated assembly connected to the machine handle, operable for displacing the link about such first axis, an implement connected to the link for pivotal movement about a second axis, a first fluid actuated assembly operatively interconnecting the link and the implement, a second fluid actuated assembly operatively interconnecting the link and the implement, a first fluid line intercommunicating a base end of the cylinder of the first fluid actuated assembly and one of the base and rod ends of the cylinder of the second fluid actuated assembly, a second fluid line intercommunicating a rod end of the cylinder of the first fluid actuated assembly and the other of the base and rod ends of the cylinder of the second fluid actuated assembly and a valve disposed in one of the fluid lines, operable to be selectively disposed in open and closed conditions whereby the opening of such valve permits the implement to be tilted relative to the machine handle and the closing of the valve function to fix the angle of the bucket relative to the machine handle.
