Abstract: A loader coupler includes left and right inner rib mounts that mate with left and right ribs of a first type of attachment coupling structure. The coupler also includes left and right outer rib mounts that mate with left and right ribs of a second type of attachment coupling structure. Left and right plunger assemblies each move between a locked and unlocked position and each includes both a first lock plunger and a second lock plunger. The left and right first lock plungers extend into left and right inner locking regions when the left and right plunger assemblies are located in the locked position. The left and right second lock plungers extend into left and right outer locking regions when the left and right plunger assemblies are located in the locked position.

Abstract: A coupler for a construction attachment includes a frame including: (i) an upper portion adapted to be secured to an associated excavator; and, (ii) a lower portion adapted to be releasably coupled to a construction attachment. The lower portion of the frame includes a first hook and a second hook. A lock member is movably connected relative to the frame and is movable between an extended position and a retracted position. The first and second hooks include respective open mouths and the lock member obstructs the open mouth of the second hook when the lock member is in the extended position. An actuator is operably connected to the lock member and is adapted to move the lock member between its extended and retracted positions.

Abstract: A coupler includes a first hook assembly comprising a first hook adapted to receive a first associated attachment pin and a second hook assembly comprising a second hook adapted to receive a second associated attachment pin. The second hook assembly selectively pivots under force of an actuator relative to the first hook assembly by an actuator. The actuator comprises a screw jack that includes a locking sleeve to prevent unintended rotation of the screw member. The actuator can be a hydraulic cylinder and the coupler can include a locking cam that moves between a retracted position and an extended position, with a supplemental lock that selectively prevents movement of the locking cam from the extended position to the retracted position. In such case, the actuator is operatively coupled to the second hook assembly and the locking cam.

Abstract: A female coupler portion includes first and second vertical ribs arranged in a spaced-apart relationship. The ribs comprise first and second hooks and first and second ears, respectively, wherein each of the first and second ears includes at least one shoulder projecting outwardly therefrom. A male coupler portion includes a frame having a front region and a rear region that is pinned to the machine. A first pair of hook engaging mounts are adapted to be received respectively by first and second hooks of a female coupler portion; a first pair of openings are adapted to receive first and second ears of a female coupler portion; first and second lock members are movable between an unlocked position and a locked position to engage the ears of the female coupler portion. The ribs can be constructed from conventional ribs. The male coupler portion optionally includes multiple mounting locations for mating with different female coupler portions.

Abstract: A mulcher apparatus includes a tractor and a mulcher unit provided to the tractor. The mulcher unit includes a tooth assembly with a holder and a cutter element with a cooperating notch portion and cross bar arrangement. The notch portion can be retrofit to existing holder arrangements. The cutter element may include various features, to enhance cutting efficiency. For example, the cutter elements may include a double-ended structure, angle tab portions at each corner portion, carbide coatings, a pair of tip portions at each end with a space therebetween, and/or a generally H-shaped configuration.

Abstract: A lift truck assembly for impaling, lifting, and transporting large bales of hay. The assembly has a frame that is adapted for attachment to a standardized Industrial Truck Association (ITA) carriage. The assembly frame has several forwardly projecting spikes for impaling and carrying the bale of hay.

Abstract: The present invention is a skid-steer attachment device with a load bearing D-ring for securing loads to the attachment device. A number of different attachment devices can be attached to a skid-steer loader, however, the preferred attachment device in this invention is a pallet fork carriage. The load securing D-ring is attached to the pallet fork carriage of the skid-steer so that loads can be secured to the D-ring by tying, strapping, or otherwise attaching the load to the D-ring. The D-ring on the pallet fork carriage functions to prevent a skid-steer loader's load from becoming dislodged prematurely.

Abstract: A bucket sweeper combination unit that is used in connection with a skid loader or skid steer which has universal mounts and remote hydraulics that power the unit. The sweeper is mounted to the lift arms of the loader ahead of the bucket. Chains are attached to the rear of the sweeper and the lift arms of the loader, and the bucket is pivotally attached to the mounting arms so that it can be pivoted when it is desired to dump the spoil material. A spoil guard is located on the bucket side of the rotating brush of the sweeper unit so that as the material is picked up by the brush, it will be deflected by the spoil guard directly into the bucket and retained in the bucket by the downwardly extending portion of the spoil guard. Preferably, the spoil guard is made adjustable so that its position can be moved closer to the rotating brush as the bristles wear shorter.
