Abstract: A mini diker farm implement system for diking a field includes one or more mini diker assemblies attached to farming equipment configured for movement through the field by a tractor. Each mini diker assembly includes a mounting bracket assembly, an H-frame assembly pivotably attached to the mounting bracket assembly, a diker paddle wheel assembly having a paddle wheel supported for rotation by the H-frame assembly, and a lift arm assembly configured to adjust a position of the paddle wheel. A diking method includes the steps of providing the mini diker farm implement system, removably attaching the mounting bracket assembly to the farming equipment, adjusting the vertical position of the paddle wheel using the lift arm assembly, and moving the farming equipment through the field to rotate the diker paddle wheel and form dikes and reservoirs.

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.

Abstract: An agricultural machine has at least one movable tool, such as a cultivating rotor, mower or raking member, spreader disc, or other driven member such as a tractor wheel or freely rotatable roller, which parts are interrupted in movement by a protective mechanism. The mechanism can be a pawl device associated with an overload coupling in the drive train that is actuated by a mechanical or electrical monitor to overload the device. The monitor can be a pivoted cover that partly overlies a rear roller or space adjacent same with projections that intercept the roller or a trip bar with contacts that opens or closes a circuit in a system that interrupts the drive to the moving parts responsive to contact with an external object. In another variation, the circuit can have sensors such as infrared or photoelectric cells to detect the presence or lack of presence of a human operator and these sensors can be placed in a tractor cab.
