A grappling attachment for an industrial or farm vehicle, such as a skid steer or tractor, includes an upper jaw and a lower jaw, which can close relative to each other to grasp roots and debris. At least one of the upper jaw and the lower jaw is formed as a plurality of first curved bars with serrations formed along edges of the plurality of first curved bars facing toward the other jaw, which serrations assist in cutting embedded roots and debris as the first and second jaws are pulled away from the embedded roots and debris, such as when the vehicle is driven in a reverse direction. A U-shaped crossmember is attached to at least one of the first and second jaws. The U-shaped crossmember has slots cut therein to hold the plurality of first curved bars in a spaced relationship. One or more edges of the U-shaped crossmember has serrations facing toward the other jaw. In a preferred embodiment, the U-shaped crossmember has serrations at both ends of the U-shaped profile.

A method of coupling a tool to a work machine including inserting a front lug of a coupling assembly into a front recess on the tool, inserting a rear lug of the coupling assembly into a rear recess on the tool, moving a retaining member of the coupler assembly to a retaining position relative to the tool to releasably mount the tool to the work machine, while simultaneously preventing movement of a hydraulic coupling manifold on the coupling assembly from moving; and moving the hydraulic coupling manifold to a coupling position with a hydraulic power transmission coupling on the tool to hydraulically couple the tool to the work machine in response to the retaining member reaching the retaining position.

The subject matter of this specification can be embodied in, among other things, a grapple assembly that includes a grapple unit having a fixed assembly, an articulating assembly having a pivot point located at a proximal end of the articulating assembly, pivotably coupling the articulating assembly to the fixed assembly, and an articulation connection point distal to the pivot point along the articulating assembly, and a linear actuator having a first actuator end and a second actuator end configured to move linearly relative to the first actuator end, the first actuator end being pivotably coupled to the fixed assembly and the second actuator end being pivotably coupled to the articulation connection point, and configured to actuate the articulating assembly relative to the fixed assembly.

A debris grapple bucket attachment for securement with the loader of a compact tractor, generally used in conjunction with the front end loader of a tractor, the attachment comprising a grapple incorporating a grapple bucket for use in combination with a front rake like member, with the grapple bucket having sidewalls, a formed back wall, all structurally integrated together, with the rake like member being secured with an electrically operated industrial linear actuator, to provide for pivoting of the rake like member from an open to a closed position as when urging debris onto its grapple bucket, and to retain the same, for removal.

A material handling bucket apparatus including a material handling bucket and method of use thereof. The material handling bucket includes a bucket back half and a bucket front half. The bucket back half is configured to engage a loader. The bucket back half includes a plurality of guide slots and a dozer scraping lip configured to engage a surface. The bucket front half is pivotally coupled to the bucket back half. The bucket front half includes a plurality of slide members receivable in the plurality of guide slots. The plurality of slide members are configured to slide within the plurality of guide slots to allow the bucket front half to move linearly and pivotally relative to the bucket back half.

A method of coupling a tool to a work machine including inserting a front lug of a coupling assembly into a front recess on the tool, inserting a rear lug of the coupling assembly into a rear recess on the tool, moving a retaining member of the coupler assembly to a retaining position relative to the tool to releasably mount the tool to the work machine, while simultaneously preventing movement of a hydraulic coupling manifold on the coupling assembly from moving; and moving the hydraulic coupling manifold to a coupling position with a hydraulic power transmission coupling on the tool to hydraulically couple the tool to the work machine in response to the retaining member reaching the retaining position.

The invention is directed to a loader with a grapple and a winch device, or a grapple and winch device combination configured to attach to a loader. The grapple has an upper grapple arm, a lower grapple arm, and a cavity formed between the upper and lower grapple arms. The winch device is housed within the cavity. The grapple and winch device are operable with a shared hydraulic actuation system, with the shared hydraulic actuation system comprising a separation of a hydraulic line to proportion the hydraulic pressure provided to the grapple and winch device.

A utility system may include at least one moveable arm, and at least one grappling assembly connected to the at least one moveable arm. The grappling assembly may include an upper claw including one or more lower grasping surfaces, and a lower claw including one or more upper grasping surfaces. The lower claw may be pivotally secured to the upper claw. The upper claw may be configured to close with respect to the lower claw. The lower claw may be configured to be wedged into at least a portion of the moveable arm so that the upper claw may compressively grasp a structure between the one or more lower grasping surfaces and the one or more upper grasping surfaces.
