摘要： The rowbucker apparatus for scraping and extending berm areas adjacent an irrigation ditch. The rowbucker comprises a frame that is towable by a tractor and supports a rotor for rotation. A tramper or trip mechanism is provided to engage the moldboard surfaces of the rotor to arrest rotation. The tramper mechanism includes at least one roller connected to a rockshaft through an arm. The rockshaft may be rotated by a hydraulic actuator to bring the roller in engagement with the moldboard surfaces in a scraping position or to disengage to deposit the scraped up material on the ground establishing a berm when the rotor is released.

摘要： As the backhoe boom 19 swings into a swing stop, hydraulic fluid is trapped in the head end 28 of the swing side cylinder 24. This trapped fluid is discharged through a cylinder relief valve, thus absorbing the boom kinetic energy and providing a smooth deceleration of the boom. Fluid discharged from the relief valve 47 is routed to the rod end of the swing cylinder and the head end of the opposite cylinder. Because of the swing linkage geometry, the cylinder rod 30 of the other cylinder had passed over the pivot axis about which the backhoe boom was swinging and thus the piston 29 of the other cylinder was caused to move in the same direction as the swing side piston 29. The movement of this piston can be utilized to provide additional deceleration torque as long as no voiding is permitted to occur in the head end of this other cylinder. Voiding only occurs when the backhoe swing control lever 38 is released prior to the backhoe boom reaching the swing stop. Voiding does not occur when the control lever 38 is maintained in a full power-on or is stroked in the power-on mode until the swing stop is contacted. Fluid from the swing side cylinder relief valve is routed to provide the necessary fluid to prevent such voiding. The routing of the fluid from the swing cylinder to the other cylinder assures that the boom deceleration is independent of whether the control lever is stroked or released.

摘要： A carriage assembly has first and second pairs of rollers rotatably connected to first and second sides of the carriage. First and second rail means are secured to spaced parallel sidewalls. The first rail device has first and second elongate rails positioned in end-to-end relationship at which the adjacent ends are spaced one from the other. Each of the first pair of rollers are rollably carried by respective first and second rails while the second pair of rollers are rollably carried by the second rail device.

摘要： A rear powered elevator equipped scraper vehicle having a bowl with a pivoted rotating floor for emptying material without an ejector device. The mechanism for actuating the rotating floor for material dumping is located non-interferingly behind the bowl and beneath the rear engine compartment and rear axle. The rearward frame members of the vehicle act as guiding tracks for a longitudinally translatable dolly which carries a forwardly extending horizontally disposed link which is pivoted to a forward portion of the rotating floor. Upon rearward actuation of the dolly by means of a substantially horizontally disposed jack mechanism, the rotating floor pivots rearwardly and upwardly to open the bowl bottom for dumping.
