A pivot coupling system that permits the use of attachable equipment such as material pushers or containment plows with a range of vehicles including all-terrain vehicles (ATVs), utility task vehicle (UTV), lawn and garden tractors, small farm tractors, small trucks, skid-steer loaders, etc.

A work machine extending in a fore-aft direction comprising a frame and a ground-engaging mechanism, the ground-engaging mechanism configured to support the frame on a ground surface; a boom assembly coupled to the frame, the boom assembly having a pair of boom arms pivotally coupled to the frame; and an attachment coupled to a fore-section of the boom arms. The attachment may comprise a guide rigidly coupled to a fore-section of the frame; a movable member coupled to the guide, the movable member moveable relative to the frame by a pair of hydraulic cylinders, the guide restricting movement of the movable member in a non-vertical direction; and a work tool coupled to the movable member wherein actuating the pair of hydraulic cylinders engages the movable member, vertically lifting or lowering the work tool relative to the frame.

An adaptor configured to move a work vehicle implement includes a work vehicle portion that includes a first receiver interface configured to couple to a work vehicle. The first receiver interface includes at least one receiver locking feature configured to non-movably couple the work vehicle portion to the first connector interface. The adaptor also includes a work implement portion moveably coupled to the work vehicle portion and a second connector interface configured to couple to a second receiver interface of the work vehicle implement. The adaptor also includes a track system comprising a slot disposed within the work vehicle portion and a slider disposed on the work implement portion, wherein the slider is configured to move along the slot, and at least one actuator configured to actuate the work implement portion with respect to the work vehicle portion along a guide path.

A swivelable adapter device used with skid steer loaders includes a mounting plate and a swiveling work tool plate for holding, rotating, and positioning skid steer attachments. Rotation about a longitudinal axis of skid steer arms is accomplished using a barrel within a barrel assembly allowing the work tool plate to be positioned from angles between horizontal and vertical. A mounting plate is attached to skid steer arms and is rigidly affixed to an inner barrel. An outer barrel with a notch plate and a work tool plate slides over a greased inner barrel. Swivel operation of the work tool plate is accomplished by hand, eliminating the need for hydraulic systems. Once positioned, the work tool plate is locked to a notch plate using a locking mechanism, such as a locking pin or locking latch. The device is reinforced with metal plates to handle torsion forces created by heavy loads.

An adaptor for quickly, easily, and safely attaching and removing compatible tools from the end of a boom of an excavating machine. A quick-change device for use in quickly changing implements utilizing a mounting plate and attachment plate in slidable communication.

A cutting tool adapter for creating an underpinning structure and method of creating the underpinning structure are provided. In some examples, the cutting tool adapter may connect a cutting tool to a working machine arm to enable the cutting tool to cut and dislodge soil below an existing foundation or structure. As the soil is cut and dislodged, it is mechanical mixed with an additive, such as a cementitious material, via the cutting tool. The mixed soil and additive may then harden in the area below the existing structure or foundation to create an underpinning structure to provide additional support for the existing structure or foundation.

A universal mounting structure for changing attachments on a construction machine includes first and second ear plates mounted disposed in spaced relation. The ear plates include a first and second pair portions of elongated cutout patterns. First and second collar/pin assembly each includes a pin and a pair of collars. Each collar has an eccentric bore configured to removably receive each end of a pin and each collar has surfaces engaging complementary surfaces of one of the first or second pair portions of the elongated cutout patterns. The first and second collar/pin assemblies are configured such that a center distance between the pins can be adjusted 1) in large increments by moving either one or both of the first and second collar/pin assemblies within the respective pair portion of the elongated cutout patterns, and 2) in small increments by axial rotation of a pair of collars about a respective pin of one or both of the collar/pin assemblies.

The invention concerns a working machine (1) comprising a mobile chassis (2) that can move on a surface of the ground, a lifting arm (3) mounted on the chassis (2) to pivot about a horizontal axis (4) for a raising and lowering movement of the arm (3), and an accessory coupler (5) that can be secured to the free end of the arm (3) by a pivot link (6) with axis parallel to the axis (4) for pivoting the arm (3) with respect to the chassis (2). The coupler (5) comprises a plate (7) having a rear face (8) facing the arm (3) equipped with said pivot link (6) of the coupler (5) to the arm (3) and an opposite front face (9). The plate (7) is provided with a through-opening (10) and at least one part (61) of the pivot link (6) connecting the coupler (5) to the arm (3) is arranged facing said opening (10).

A reconfigurable material moving attachment for a vehicle includes a blade having a blade working face directed toward a front of the blade; and a coupling mechanism for reversibly mounting the blade to the vehicle. The coupling mechanism includes a first coupling portion fixed to the blade and a second coupling portion attachable to the vehicle. The second coupling portion is releasably interconnectable with the first coupling portion in: (i) a forward pushing configuration, in which the blade working face is directed away from the vehicle for pushing of the blade during forward operation of the vehicle to collect and push material in a material collection space adjacent the blade working face, and (ii) a back-dragging configuration, in which the blade working face is directed toward the vehicle for pulling of the blade during reverse operation of the vehicle to collect and back drag material in the material collection space.

An earth levelling blade assembly for mounting on the lift arms of a loader includes a laterally extending main blade and two shoes supported at opposing ends of the main blade for sliding engagement along the ground. The shoes are supported for movement between a forward position ahead of the main blade and a rearward position behind the main blade, as well as being adjustable in height relative to a bottom cutting edge of the main blade. A coupling arrangement between a first mounting frame on the lift arms of the loader and a second mounting frame on the rear mounting face of the main blade (i) supports the second mounting frame to be freely pivotal about a forward axis relative to the first mounting frame in which the forward axis is oriented in the forward working direction of the loader and (ii) supports the second mounting frame to freely translate relative to the first mounting frame along an upright axis.
