A front loader includes a link operating mechanism spanning a bucket and a stand. The link operating mechanism is configured to cause, using a swing force of the bucket, a bending and stretching link to bend so that propping and supporting of the bending and stretching link are released.

Disclosed embodiments include power machines, implement coupling systems and methods in which hydraulic or electric coupling between an implement and the power machine is made automatically using an existing actuator, for example a tilt actuator, of the power machine. Thus, additional actuators are not required to achieve hydraulic or electric coupling. In exemplary embodiments, power coupling is also free from the process of mechanically coupling the implement to the implement carrier. Also, in exemplary embodiments, a machine side coupler assembly moves with the implement after a connection is established, despite the implement coupler assembly being removed from the implement carrier. This allows the same implement carrier to be used on all similarly sized machines.

A quick coupler (1) for attaching a tool (2), comprising an attachment bracket with two parallel attachment pins (3a, 3b), to an earth moving vehicle, where the quick coupler (1) comprises a frame (4) with a first cutout (5) and a second cutout (6) arranged substantially perpendicular to each other, which are adapted to cooperate with the respective attachment pin (3a, 3b) of the tool (2). The quick coupler (1) further comprises at least one, in relation to the frame (4) moveable locking arrangement (9), adapted to delimit the second cutout (6) in a direction parallel to the first cutout (5), whereby one of the attachment pins (3aq, 3b) of the tool is locked in the second cut-out (6) and at least one locking segment (18a, 18b) arranged to be rotated in relation to the frame (4) in at least a first and a second direction between different positions, whereby the locking segment (18a, 18b) in at least one position delimit the first cut-out (5) and locks the second of the attachment pins (3a, 3b) of the tool.

A tool holder includes a locking cylinder provided with two first gripping pins extending laterally from each side of the fixed part thereof, and two second gripping pins extending laterally from each side of the moving part thereof. The tool includes at least two reception assemblies each having a first receiving portion and a second receiving portion the openings of which are each facing and provided to receive one of the first gripping pins and one of the second gripping pins for retaining the tool on the tool holder. The tool is locked on the tool holder by means of the locking cylinder by moving each gripping pin into abutment at the bottom of the associated receiving portion thereof.

A loader attachment system is configured so as to detachably attach a loader to a vehicle by detachably attaching a mast of the loader to a loader mount fixed on the vehicle. The loader attachment system includes a support device, a location device, and an engagement device. The support device is configured to support the mast on the loader mount so that the mast is rotatable relative to the loader mount. The location device is configured to locate the mast supported on the loader mount by the support device at an attachment position. The engagement device is configured to engage the mast at the attachment position with the loader mount so as to prevent the mast from rotating in a direction to detach the mast from the loader mount. The support device, the location device and the engagement device are configured independent of one another.

The invention solves this problem by retrofitting the machine and implement with mating hydraulic connector blocks, which automatically make the hydraulic connections when the retrofitted machine attaches to the retrofitted implement. In addition, the retrofitted machine is still compatible with non-hydraulic implements. Both a method and a kit are described and claimed.

Provided is a work vehicle including a cabin and a loader work device. The work vehicle includes: a vehicle main body; a main body rear; front and rear wheels; a bucket; a lifting arm connected to the bucket to lift the bucket; a boom support connected to the lifting arm; a rear link having one end coupled to a first boom support hinge part of the boom support and an opposite end coupled to a rear hinge part of the main body rear; a boom cylinder having one end coupled to a second boom support hinge part of the boom support to rotate the boom support; and a rotation link having one end coupled to a third boom support hinge part of the boom support and an opposite end coupled to a front hinge part of the vehicle main body.

A quick joint of a front loader, the quick joint includes: a coupling member (30) having a hook shape and pivotally connected to a first pivot point (P1) of a boom post (20) through a first pivot shaft (31); a spring member (32) for applying an elastic force in a direction of releasing the coupling member (30) from a coupling target shaft (14) disposed on a boom post support (10) which is attached to a tractor (1); a lock unit (34) having a part making contact with the coupling member (30), and provided with a lock pin (36) for restraining behavior of the coupling member (30) at a coupling position (A1); and a guide slot (38) having an arc shape and formed in the boom post (20) to define a moving path of the lock pin (36) when the lock unit (34) rotates.

A rotary ditcher attachment is selectively mounted onto the bottom of an excavator implement. The rotary ditcher attachment has an attachment frame including a mounting bracket for releasable mounting onto a tool mount on the boom of the excavator implement. A rotary disc assembly on the attachment frame includes a rotor supported for rotation relative to the attachment frame about a disc axis, and a plurality of blades supported on the rotor for cutting into the ground as the rotor is rotated. A drive motor for driving rotation of the rotor relative to the attachment frame is supported on the attachment frame so as to be releasable from the boom together with the attachment frame.

A quick hitch for coupling and decoupling a tool at a rotator for rotating the tool that has a rotator attachment part that is attachable to an excavator arm or the like and that has a rotary rotator part rotatable relative thereto, wherein the quick hitch has a coupling part at the rotator side that is fastenable to the rotatable rotary rotator part and has a coupling part at the tool side, wherein the two coupling parts can be brought into engagement with one another and can be latched to one another by at least one latch element. A latch operating actuator is provided at the rotator attachment part for actuating a latch adjustment part movably arranged at one of the coupling parts for the unlatching and/or latching of the latch element, the latch operating actuator being rotatable about the rotator axis of rotation relative to the latch adjustment part.
