Power machines with implement carriers that can sense the proximity of an implement to the implement carrier with a plurality of sensors. Such sensing is indicative of the likelihood of an implement being positioned adjacent to the implement carrier. In some embodiments, a sensor detects whether a locking mechanism is activated.

A carrier for coupling loader arms to an implement of a work vehicle includes a pair of brackets coupled by a cross-rod. Each bracket includes an inner wall spaced apart from an outer part. At least one of the inner walls defines a latch slot. The carrier includes a latch mechanism movable between latched and unlatched positions. The latch mechanism includes a latch plate having a retaining flange with an engagement surface, a pair of lock pins and a pair of latch receptacles associated with the brackets. When in the latched position, the latch mechanism has the lock pins received in the latch receptacles and the engagement surface disengaged from the one of the inner walls. When in the unlatched position, the latch mechanism has the retaining flange passed through the latch slot and the engagement surface engaged with the one of the inner walls.

A tractor attachment mountable on a loader boom of a tractor and a tractor attachment kit. In one embodiment, the tractor attachment is a grapple assembly, and the grapple assembly kit includes a mounting assembly, a plurality of clamping units, and a plurality of support units. The clamping units and the support units are removably mountable on the mounting assembly and may be arranged in different combinations on the mounting assembly. Such combinations may range from a single clamping unit mounted on the mounting assembly to a mixture of clamping units and support units mounted on the mounting assembly to several clamping units mounted on the mounting assembly. The clamping units may have alternative pivot points to permit jaws of the clamping unit to close at different speeds and with different forces. One or more fangs may be removably mounted on a clamping unit to enhance its grip.

A quick hitch for mounting an implement on a machine includes at least one lug for connecting the machine and a securing assembly for securing the quick hitch to an implement. The securing assembly includes an over-center mechanism and a locking member. The over-center mechanism includes a first member pivotal at an axis D relative to a chassis, a first end of a first link that pivots at an axis E relative to a first arm of the first member, and a second end of the link that pivots at an axis F. When the securing assembly is in a first position with the hitch secured to an implement, axis E lies on a first side of a line between axes D and F. When in a second position with the hitch unattached, axis E lies on a second side of a line between axes D and F.

An attachment for the rear of a skid steer type vehicle to connect any of a variety of commercially available attachments to the rear of that vehicle. A pair of hydraulic actuators articulate the arm assembly relative to the plate assemblies affixed to the vehicle to raise and lower the attachment.

The coupler is mounted on the end of the boom of a boom-tractor, and provides secure locking-in of a bucket. The coupler having been set to its latched-open condition, the tractor is driven to the bucket so that a bottom-lug of the bucket enters the coupler, whereupon the bucket is picked up and is automatically securely locked into coupler, without any manipulation of the coupler being required of the tractor-driver other than manipulation of the boom. For setting the bucket down on the ground, after use, the driver manually pulls out a slider of the coupler. That action sets the coupler into its slider-held condition, whereby when the tractor is driven away from the bucket, the coupler is automatically left set in the said latched-open condition.

The invention relates to a quick-change device (IO) having at least one locking bolt (26) and a motor drive which moves the locking bolt (26) into a locking position and an unlocking position, wherein the drive (16) has an energy connection (28a, 28b) and output means (34) interacting with the locking bolt (26), wherein the drive (16) comprises a rotary drive (30) having a motor and an output shaft (34), wherein the output shaft (34) is mechanically connected to the locking bolt (26), with the result that the locking bolt (26) is movable along an actuation axis. The invention is distinguished by the fact that the drive (16) has an attachment (20) for a shaft-hub connection, on which attachment a tool for manual actuation can be mounted, with the result that a manual actuation acts directly on the output shaft (34) and here the attachment (20) is arranged coaxially to a rotary connection (32a, 32b) of a gear shaft (32c, 32d).

A coupler for securing an attachment to an earth working machine. The coupler Includes 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 of 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 coupler assembly for coupling a work tool to a work machine. The assembly includes a body, a first locking mechanism, and a second locking mechanism. The first locking mechanism is pivotable about a pivot from a first position to a second position and is configured to be coupled to the work tool in the first position and decoupled in the second position. The second locking mechanism includes a pin having a first end and a second end, a tab coupled to the pin proximate the second end, and a spring disposed between the first end and the second end. The second locking mechanism is axially and pivotably movable about an axis such that the second locking mechanism includes a locked position and an unlocked position. As the first locking mechanism moves from the second position to the first position, the second locking mechanism automatically moves to the locked position.

An interface for an implement that is to be operably coupled to a power machine includes an implement carrier mountable to a power machine for securing the implement for use with the power machine. The implement carrier includes an implement carrier frame, a locking feature for securing an implement, and a coupler block that is pivotally mounted to the implement carrier frame for engaging couplers on the implement. Implements and adapters configured to interface with the implement carrier are also disclosed.
