ABSTRACT:
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.
