A quick coupler for coupling a tool such as an excavator bucket, a clamshell grapple or demolition shears to a tool operator such as an excavator arm or the like. The quick coupler including a coupling mount for receiving a first locking part and a locking mount for receiving a second locking part, wherein a locking element for locking the second locking part in the locking mount is at least associated with the locking mount, with the locking element being actuable by an adjustment actuator. The quick coupler can be electrically controllable, with the quick coupler having an electric drive for actuating the adjustment actuator for the locking element.

A coupler for securing an attachment to an earth working machine. The coupler comprises a coupler body that presents a receptacle having a capture region. A pin of an attachment can move into and out of the capture region. A retainer can capture the pin in the capture region but the retainer can be moved by a hydraulically driven driver to a position to allow release the pin from the capture region. A trigger that the pin will strike when the pin moves into or out of the capture region, decouples the driver from the retainer and the retainer is then allowed to be biased back to its retaining position by a spring.

A pin grabber coupler and method for locking and unlocking a tool to a machine is disclosed. The pin grabber coupler may comprise a tertiary lock configured to pivot between an unlocked TL position and a locked TL position. The tertiary lock may include a first and second shoulders, a leg, a tab, a latch, a bias member and a detent. The bias member may be configured to exert a biasing force on the tertiary lock to urge the tertiary lock to the locked TL position. The detent may be configured to exert, when in a hold position, a holding force against the latch that is greater than the biasing force exerted by the bias member. When the detent is in a release position, the holding force applied by the detent against the latch is less than the biasing force applied by the bias member.

A monitoring system for a work vehicle having a lift system to which an implement is attachable via a connection assembly includes a weight detection subsystem operable with the lift system and configured to transfer signals representative of a weight supported by the lift system. The monitoring system also includes a position detection subsystem operable with the connection assembly and configured to transfer signals representative of a state of the connection assembly. A controller is in operable communication with the weight detection subsystem and the position detection subsystem and is configured to receive signals from the weight detection subsystem and from the position detection subsystem, determine a condition of the connection assembly based on the signals received, and output a signal based at least in part on the determined condition.

Power machine bucket implements include a rear wall structure, a bottom wall structure adjoining the rear wall structure at a bend region, and a two-piece brace. The two-piece brace includes a first piece attached to and extending along a portion of the bottom wall structure and a second piece, separate from the first piece, attached to the back side of the rear wall structure.

Quick couplers release one attachment and quickly attach another attachment to the end of the arm. Different attachments are available with differing widths. The attachments comprise of a front and a back pin that are able to engage with the quick coupler. The front pin and/or the back pin are preferably presented mounted to side plates that are secured to the bucket of the attachment. The spacing between the side plates may vary from attachment to attachment. The present invention is a packer that is able to engage with a quick coupler so as to prevent slop when attachments narrower than the quick coupler are used.

A work-tool mounting mechanism detachably attaches a predetermined work tool that includes an engaged portion including an engagement hole. The mechanism includes: an engaging portion that engages the engaged portion and includes; a lever that is rotatably attached to the engaging portion; a lock pin that is movable between a locked position and an unlocked position, the lock pin being inserted into the engagement hole in the locked position, and not inserted into the engagement hole in the unlocked position; and a linking tool that moves the lock pin between the locked position and the unlocked position with a rotation of the lever. The linking tool includes a regulating portion that regulates the lock pin at the locked position from moving to the unlocked position.

An attachment assembly for use with a work machine includes an attachment adapter coupled to the work machine and fixed relative thereto and an attachment frame including a member defining an attachment point configured to engage, into an engaged mode, with the attachment adapter when a front suspension system of the work machine is raised to a raised position, and configured to disengage, into a disengaged mode, from the attachment adapter when the front suspension system is lowered to a lowered position, the attachment adapter configured to travel with the work machine when in the engaged mode and the disengaged mode, and the attachment frame configured to travel with the work machine when in only the engaged mode.

A system for connecting an implement to a machine. A universal adapter to connect implements with machines. A frame with brackets on one side to couple to lift arms and tilt operators on a machine such as an earthmoving vehicle. Brackets on the other side of the frame to detachably couple to the implement. A locking mechanism on the frame with operative handles to engage locking pins on the adapter with the implement between a release and locked position.
