In a backhoe, a main boom, a jib boom having an upper end and a lower end, a forked member having an upper end rigidly secured to the lower end of the jib boom and having a lower bifurcated end, a yoke pivotally mounted on the lower bifurcated end of the forked member on a tilt axis and having its arms extending upwardly between said bifurcated end, a bucket pivotally mounted on the lower end of the yoke for pivotal movement on the yoke on a bucket pivot axis transverse to said tilt axis, first manually controlled means for pivoting the bucket about said bucket pivot axis, a double-ended fluid cylinder pivotally mounted between the bifurcated end of the forked member on a third axis above and parallel to said tilt axis locating said cylinder between the arms of the yoke, said fluid cylinder including a housing having a central piston and a rod at each end extending outwardly of said housing parallel to said bucket pivot axis, one rod engaging with one arm of the yoke and the other rod engaging with the other arm of the yoke, the total length of the rods at least equal to the spacing between the arms of the yoke so that the rods always engage both arms, second manually controlled means for said fluid cylinder, the extension of a selected rod resulting in the simultaneous retraction of the other rod and the exertion of a direct force upon a selected arm of the yoke by said selected rod thereby selectively pivoting said yoke and bucket around said tilt axis by said selected rod.
