Abstract: A quick attach accessory tool mounting frame is adapted to be mounted onto a quick attachment bracket and held in place. The adapter frame has spaced side plates that slide over a bracket and with a linear movement can be held in place on the bracket. The frame is held in place on the bracket with bolts that draw the bracket and frame together.

Abstract: A bracket and frame assembly permits attaching and removing a bucket or other tool to and from an arm of an excavator, backhoe, or the like. The bracket and frame assembly comprises two portions, a bracket and a detachable frame. The bracket mounts onto the arm of the implement. The bracket carries a latch member. The bracket can be moved onto a frame on a bucket or other tool, and is latched in place without dismounting from the backhoe, excavator or the like. The latch member can be released, either manually or under power, and then by manipulating the arm, the tool and frame can be removed from the bracket and a new tool mounted. The engaging portions of the frame and bracket are such that as wear occurs, the parts will compensate and remain secured without play or slop.

Abstract: A power attachment is attachable to a power machine which has a power circuit. The power machine also includes an operator input device receiving an operator input and providing an output signal indicative of the operator input. The attachment includes a tool and an actuator, coupled to the tool, to drive the tool. The actuator is also connectable to the power circuit of the power machine. A controller is operably coupled to the actuator and is operably couplable to the operator input device. The controller controls operation of the tool based on an operator input signal provided by the operator input device.

Abstract: The present invention relates to an auger mount device for coupling an auger to a vehicle such as an excavator, skid steer loader, or the like, having a dipper stick and a bucket link. The auger mount device comprises a mounting plate having a dipper end, an auger end, and a pivot aperture adjacent to the dipper end. The pivot aperture is suitable for mounting the auger mount device to the boom. A fin is attached to the mounting plate. The fin defines a slot suitable for attachment to the bucket link. The auger is mountable to the auger end.

Abstract: A loader boom assembly has articulated lift arms that have first and second lift arm sections pivotally mounted together. The rear lift arm section is pivotally mounted to rear portions of a prime mover frame. The main lift arm section is substantially longer than the first lift arm section and pivots on the outer end of the rear lift arm link. The lift arm sections are in a folded position when the lift arms are lowered, and a control link is provided to cause the lift arms to unfold as the lift arms are raised to keep the forward portion of the main lift arm section moving along a generally vertical path after a selected lift height to provide a better forward reach of the boom assembly at the higher range of lift. The proportional lengths of the lift arm sections and the control link and the placement of the pivot points and actuators on the main frame also provide structural integrity and efficient power utilization.

Abstract: A system for removably mounting a trenching attachment to hook and eye mounts on an end of a power unit. The trenching attachment includes a mounting frame having hook-engaging shafts and eye-engaging pins, a head drive assembly, a trenching boom assembly pivotally mounted to the head drive assembly, and a hydraulic boom cylinder for raising and lowering the boom assembly with respect to the mounting frame. With the boom assembly supported in a three-point stance adjacent the power unit, the cylinder is actuated in a first direction to rotate the mounting frame with respect to the boom assembly, and engage the shafts with the mounting frame hooks. Further actuation of the cylinder in the first direction rotates the mounting frames with respect to the boom assembly and power unit until the mounting frame pins are adjacent the mount eyes. A grease cylinder on the mounting frame is actuated to extend the pins and engage the mount eyes.

Abstract: A gas spring for supporting a cab enclosure pivotably mounted to the body of a skid-steer vehicle. A stop tube is mounted to a piston rod and is telescopically cooperable with a cylinder body. Two parallel slots extend in a transverse direction through the stop tube. A stop slide has a pair of legs which are adapted to slide within the slots of a stop tube. A release portion of the stop slide is sized to permit the cylinder body to pass between the legs, while a stop portion is sized to prevent the cylinder body from passing between the legs. A spring urges the stop slide toward a stop position at which the stop portion of the stop slide is aligned with the cylinder body when the piston rod is extended. The cab enclosure is thereby latched to a tilt-back position.

Abstract: The hydraulic system of this invention is for operating a tree processing implement on a work vehicle so that during a first part of an operating cycle the implement is supplied by two hydraulic pumps jointly, while during another part of the operating cycle the implement is supplied by only one of the pumps. The result is that during the first part of the cycle the implement moves rapidly but during the other part it moves slowly.
