Abstract:
A removable scraper device is described herein. The removable scraper device includes an attachment element and a socket defined by the attachment element, wherein the socket is configured to receive a post of a scraper element therein. The removable scraper device further includes a slot defined by the attachment element, wherein the slot is configured to receive a portion of a bucket of a wheeled-machine therein. The removable scraper device further includes an aperture defined by the attachment element and a bolt sized to be received within the aperture. In some embodiments of the removable scraper device, the bolt and aperture are configured to selectively press the attachment element against the bucket to removably secure the removable scraper device thereto.
Abstract:
An assembly for detachably connecting an implement to a boom of a machine is disclosed. The assembly may include a stick and a coupler. The stick may have a first end portion configured for pivotal connection to the boom. The stick may also have a second end portion narrower than the first end portion. The coupler may be configured for detachably connecting the implement to the second end portion of the stick.
Abstract:
A coupler to secure a work attachment to a work vehicle is disclosed. The work attachment includes a first pin and a second pin, while the coupler body has a first engagement portion which is configured to accept the first pin and a second engagement portion configured to accept the second pin. The coupler body has a guide and a slider configured to slide along the guide. The body of the slider includes a first locking portion and a second locking portion. The coupler has a trigger located on the coupler body such that the trigger is released by contact with the second pin; and a first actuator that is activated by release of the trigger. When the trigger is released the first actuator moves the slider along the guide into an engaged position where the first locking portion engages and retains the first pin in the first engagement portion of the coupler body and the second locking portion engages and retains the second pin in the second engagement portion of the coupler body at the same time.
Abstract:
A modular system for connecting attachments to the extension arm of a construction machine, wherein each module has a standardized coupling arrangement. As a result, each module is compatible with another module to provide great versatility in configuring the machine. Additionally, the system includes a variety of different modules and a mechanism for remotely activating the coupling between modules.

Abstract:
The present invention provides an apparatus (10), as shown in the figur, that lifts, secures, splits and/or crushes tree stumps or other materials, particularly wooden materials and other materials that may be present at an excavation site. The apparatus is characterized in part by a two pivot point design. A first pivot point (14) allows for the pivotable operation of an engaging unit (12) which grabs and lifts the tree stump. The engaging unit further acts as a durable and secure support member for the tree stump during the splitting and crushing process. The second pivot point (14') allows for pivotable operation of a cutting device which facilitates splitting and crushing of the stumps.
Abstract:
A bucket assembly (13) includes a prime mover mounting portion (21) which includes a transverse attachment member (23), opposite ends of which are fastened to support arms (25). At their lower ends the support arms are connected to the bucket rear wall (9) by pivots (39). At their upper ends the arms (25) are coupled to the fixed pivots (29) of respective bell cranks (31). The bell cranks (31) have input moving pivots (33) which are respectively coupled to the rods (34) of hydraulic tilt rams (37). The bases of the cylinders of the hydraulic rams are coupled to their respective support arms (25) by pivots (39). The output moving pivots (35) of the bell cranks are coupled to rear wall shafts (41) which in turn are connected by pivots (43) to the upper border of the rear wall (9) of the bucket.
Abstract:
An apparatus and method of installing a shank onto a ripper assembly of a tractor or crawler. A rotating shank installer (RSI) is welded onto a front face of a ripper assembly of a tractor, e.g., on the outside surface of a pocket beam. A portion of the RSI is allowed to rotate with respect to the pocket beam. With the shank in a substantially horizontal position with respect to the ground, the shank is secured between two plates of the RSI using pins wherein the plates can rotate with respect to the pocket beam. The shank is locked in place by two pins placed through the plates and the shank's weight is unbalanced with respect to the RSI. The ripper assembly is elevated causing the shank to rotate within the RSI to a substantially vertical position. The crawler is moved forward while lowering the ripper assembly in order to rip a groove into the ground with the bottom portion of the shank where the shank lowers into the ground. The RSI is disconnected from the shank wherein the shank is held in place by the grove. The bottom of the pocket is positioned over the top of the lowered shank and the pocket is lowered so that the shank is installed within the pocket and secured therein.
Abstract:
A controller for a power machine attachment (12). The controller includes a computing device (52), having associated memory, and at least one sensor (104). The memory is programmed with an application program specific to the type of attachment, and operating parameters specific to planned use of the attachment (12).
