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.
Claims4
An agricultural implement for forming mounds or berms of material comprising:
- (a) a frame having a hitch attachable to a prime mover;
- (b) an elongate rotor mounted for rotation on said frame, said rotor having a plurality of blades defining moldboard surfaces for scraping and forming material;
- (c) a rock shaft mounted for rotation on said frame, said rock shaft being generally parallel to said rotor and spaced from said rotor said rock shaft extending substantially coextensive with said rotor;
- (d) spaced apart arm means extending from said rock shaft and having at least a pair of longitudinally spaced apart rollers associated therewith;
- (e) hydraulic shock absorbing means having a rod end and a cylinder end and extending between said hitch and frame to absorb shock loading imposed thereon;
- and
- (f) hydraulic actuating means for selectively rotating said rock shaft from a first position with said rollers engaging one of said rotor blades to arrest rotation of the rotor to a second position with said rollers out of engagement with the rotor thereby permitting rotation of the rotor.
