Abstract: An excavator attachment alignment tool has cooperating tool body portions mounted to a cross tube defining an axis. The tool body portions are moveable relative to the cross tube to define a lower hook portion having surfaces to accommodate and support an engaged excavator attachment pin parallel with the tool axis, with the lower hook portion positionable for lifting engagement with the excavator attachment pin. Aligned cylindrical bushings are mounted to opposed surfaces of the body portions in alignment with the tool axis, with the cross tube engaged and extending generally between the bushings, with spacing of the cooperating tool body portions fixedly adjustable along the tool axis for accommodating a width of an associated excavator link or stick to which an excavator attachment is to be attached or removed; and wherein the tool body portions are mounted in a manner to resist independent rotation of either body portion.

Abstract: A tree stump excavation tool for use mounted for rotation from an excavation machine arm has first and second side plates extending from a body and a unitary plate mounted to lower ends of the side plates. The unitary plate has a generally helical profile and defines a blade with multiple, pointed teeth integrally formed along its forward edge. The teeth, disposed for cutting engagement with a substrate of soil and stump roots, are laterally spaced apart along the axis of rotation of the tool and angularly spaced in a direction of substrate ripping motion, wherein the teeth are engaged separately and in sequence for cutting the substrate. An excavation machine with a tree stump excavation tool is also described.

Abstract: A staggered edge bucket excavation tool has a body formed by side-leading edge plates, a back sheet, and a plate with a front leading edge spanning a region of the bucket between edge plates. The tool defines a volume for receiving material excavated from a hard packed substrate. Two or more teeth may be mounted along the front leading edge, with each tooth defining a forward surface non-aligned with forward surfaces of all other teeth, thereby disposed for individual, sequential initial engagement with the substrate during excavation. The teeth define a flat plane generally parallel to the planar plate. Each tooth defines an excavation angle between a surface of the tooth and the axis of rotation, and the excavation angle of each tooth being different from excavation angles of all other teeth. In implements, the front leading edge defines multiple edge portions or defines a single multiple edge portion.

Abstract: A single pointed ripper bucket excavation tool (SPRB) for use mounted to an arm of an excavation machine has a body mounted for rotation from the arm and a pair of generally flat, side plates mounted to the body and narrowing from a first width in a region of the body to a second, relatively smaller width at a tip region spaced from the body. A single ripper tooth is mounted in the tip region of the ripper bucket. One or more plates are mounted to span a region between the side plates, rearward of the ripper tooth in a direction of ripping motion, to define, with the side plates, a ripper bucket volume for receiving material ripped from the substrate during ripping motion.

Abstract: A multi-shank ripper excavation tool has a body mounted from an arm, e.g. a dipper arm or a boom arm, and at least first and second shanks mounted to the body. Each shank is perpendicular to an axis of rotation of the tool, and each the shank includes a ripper tooth positioned for ripping engagement with a substrate. The shanks and ripper teeth are laterally spaced apart along the axis of rotation relative to the arm, and the ripper teeth are angularly spaced apart in a direction of substrate ripping motion. In some implementations, plates are mounted to span a region between two or more shanks, rearward of the teeth in a direction of ripping motion, and define, with the shanks, a bucket volume for receiving material ripped from the substrate. Methods for ripping excavation of a substrate employing the above excavation tools mounted on a dipper stick or a boom arm are also described.

The tool does not have a bucket configuration. The shanks are arranged on the axis so the, as the tool is rotated about the axis, the shanks engage the substrate serially and axially offset.

Abstract: A fluid line connector assembly includes a first part defining a fluid channel; and a second part including an outer body and a member mounted for adjusting movement relative to the outer body in a direction normal to an axis of engagement in response to relative motion of the first part and the second part when the first part and the second part are connected, the member defining a fluid channel within the body. The first and second parts together define the axis of engagement along which the first and second parts are releasably connectable, the fluid channel of the first part being adapted to connect to the fluid channel of the second part, and, when the first and second parts are connected, the fluid channel of the second part remains in fluid flow connection with the fluid channel of the first part during adjusting movement of the member relative to the outer body of the second part.

Abstract: A non-spill, multi-line fluid connector includes a first part and a second part removably connected to the first part. Each of the first and second parts includes a plurality of fluid channels, each of which connects to a corresponding fluid channel of the other part without fluid spillage. The fluid channels in each part can be arranged concentrically, which enables the parts to be rotated relative to each other while maintaining the fluid connections. One part can be incorporated into a latch pin of a tool coupler, and the other part can be incorporated into a latch bracket attached to a hydraulically operated tool, wherein the latch bracket receives the latch pin to lock the tool to the tool coupler and to establish one or more hydraulic connections to the hydraulic tool. A locking assembly secures together the first part and the second part when fluid pressure is applied.

Abstract: A multi-line fluid connector has a pin and a receptacle, each including a plurality of fluid channels, and a fluid connector make-before-break connections between the fluid channels of the pin and corresponding fluid channels of the receptacle when the pin is moved into engagement with the receptacle.
