Tool actuator with adjustable attachment mount

A fluid-powered laterally tiltable bucket assembly, usable with a vehicle having an arm and a rotation link associated therewith for rotation of the bucket assembly in a first plane defined by movement of the rotation link relative to the arm, each of the arm and rotation link having an attachment member located toward a free end thereof, the bucket assembly comprising:

• one of a plurality of buckets, each having a working edge extending laterally, generally transverse to the first plane, a first bucket attachment member and a second bucket attachment member located away from said first bucket attachment member where the distance between said first and second bucket attachment members varies from bucket to bucket within a range of bucket attachment member distances;
• a body having a longitudinal axis and first and second ends;
• an attachment bracket rigidly attached to said body and having an external first bracket attachment member located generally along said body axis for pivotal attachment to the vehicle arm by the arm attachment member and an external second bracket attachment member located generally along said body axis away from said first bracket attachment member for pivotal attachment to the rotation link by the rotation link attachment member, said first and second bracket attachment members being selectively detachable from the arm and rotation link attachment members, wherein with said first and second bracket attachment members attached to the arm and rotation link attachment members, movement of the rotation link causes said body to rotate about the vehicle arm with movement of said longitudinal axis of said body in generally parallel alignment with the first plane, and wherein the bucket assembly is selectively detachable from the vehicle arm and rotation link;
• an output shaft rotatably disposed within said body in general coaxial arrangement with said body and having a first shaft end portion extending at least to said first body end and a second shaft end portion extending toward said second body end, said first shaft end portion having a first shaft attachment member attached thereto which is releasably attachable to said first bucket attachment member;
• a member pivotally attached to said second shaft end portion to pivot about an axis generally transverse to said second shaft end portion, said pivotable member having a second shaft attachment member attached thereto which is releasably attachable to said second bucket attachment member, said pivotable member being selectively pivotable to move said second shaft attachment member within a range of distances corresponding to said range of bucket attachment member distances and position said second shaft attachment member at a selected distance from said first shaft attachment members such that said first and second shaft attachment members are spaced apart by the same distance as said first and second bucket attachment members for said bucket being attached to said shaft, said first and second shaft attachment members releasably attaching said bucket to said shaft for rotation with said shaft through a second plane extending laterally, generally transverse to the first plane;
• and
• a linear-to-rotary torque transmitting member mounted for longitudinal movement within said body in response to selective application of pressurized fluid thereto, said torque-transmitting member engaging said body and said shaft to translate longitudinal movement of said torque-transmitting member into rotational movement of said shaft relative to said body, whereby said bucket attached to said shaft is rotatable in the first plane and laterally tiltable in the second plane.
