| 20080222926 | SNOWPLOW WITH PIVOTING SIDEBLADES - The left and right sideblades are hinged to the mainblade about vertical axes, and can pivot each through 180°. The sideblades are rotated by means of left and right hydraulic rotary actuators. The actuator includes a piston formed with helical splines, which drive a rotor sleeve of the actuator to rotate in a single-plane-circle when the piston is driven axially. The journal bearings in the rotary actuator are supplemented by bearings provided in a coaxial lower hinge, which are of much greater journal capacity than the bearings in the rotary actuators. The lower hinge protects the hydraulic rotary actuator from shocks due to the sideblade impacting against a kerb. | 09-18-2008 |

| 20090051163 | COUPLING APPARATUS FOR RELEASABLY COUPLING HYDRAULICALLY POWERED WORK IMPLEMENTS TO A WORK VEHICLE - A coupling apparatus for releasably coupling a hydraulically activated work implement to a work vehicle includes an implement attachment device for attaching a work implement to a work vehicle, a first coupling assembly, and a second coupling assembly. The implement attachment device includes a forward side for facing the work implement and a rearward side for facing the work vehicle, first mounting members extending from the rearward side for mounting the implement attachment device to at least one boom arm of the work vehicle, and second mounting members for mounting the implement attachment device to the work implement. The first hydraulic coupling assembly extends from the rearward side, and includes a first coupler configured for fluid communication with a hydraulic power source on the work vehicle. The second hydraulic coupling assembly is mountable to the work implement, and includes a second coupler configured for fluid communication with a hydraulic system of the work implement, the second coupler being shaped and configured for engaging the first coupler. The first coupler is movable between a retracted position and an extended position so as to selectively engage the first coupler with the second coupler when the work implement is attached to the implement attachment device and the second hydraulic coupling assembly is mounted to the work implement, for placing the hydraulic system of the work implement in fluid communication with the hydraulic power source. | 02-26-2009 |
| 20100052289 | Trailer with Four Wheel Steering and Independent Suspension - A trailer having a frame extending along a longitudinal axis and having a front end and a rear end, a steering linkage coupled to the frame, a pair of front wheel assemblies coupled to the front end of the frame, and a pair of rear wheel assemblies coupled to the rear end of the frame. Each wheel assembly includes a wheel carrier having a pivot member pivotally coupled to the frame along a steering axis, the wheel carrier being coupled to the steering linkage so that actuation of the steering linkage pivots the wheel carrier about the steering axis, and a wheel rotatably coupled to the wheel carrier along a wheel axis. The wheel axis is oriented approximately perpendicular to the steering axis, and the wheel axis is offset from the steering axis. | 03-04-2010 |
| 20100258662 | BALE PROCESSOR HAVING IMPROVED SHREDDING ROLLER - A bale processor, having a support surface for supporting a bale of crop material, a shredding roller positioned at one end of the support surface, the shredding roller having an elongate roller body, the roller body configured to rotate about an axis of rotation, and a feed mechanism positioned on the support surface, the feed mechanism configured for urging the bale towards the shredding roller. The shredding roller includes at least one separating section having at least one impacting member that protrudes outwardly from the elongate roller body, the at least one impacting member configured to impact the bale when the roller body rotates so as to separate the crop material therefrom. The shredding roller also includes at least one conveying section configured to engage a portion of the bale and to direct that portion towards the separating section in a longitudinal direction aligned with the axis of rotation of the roller body. | 10-14-2010 |
