61	Mulcher bar assembly	US3574320D	1969-05-15	US3574320A	1971-04-13	SIGMUND DONALD F
A mulcher bar assembly adapted for use with a plow and designed to trail the plow to mulch the freshly turned soil. A first pair of spaced apart arms are adjustably secured to the main plow beam and extend rearwardly and laterally therefrom. A second pair of spring loaded arms are pivotally and vertically adjustably secured at their upper ends to a first pair of arms and extend downwardly therefrom. A horizontal bar means is adjustably secured to the lower ends of the second pair of arms and has a plurality of spaced apart teeth extending downwardly therefrom. The spring loaded arms yieldably urge the teeth into the soil to mulch the soil as the plow is moved in the field. The second pair of arms, bar and teeth may pivot upwardly and rearwardly as a unit if a foreign object is struck by the teeth to prevent damage to the assembly and plow.
62	Plow mulcher	US3566974D	1968-11-20	US3566974A	1971-03-02	KOPASKA ARNOLD F
A plow having a pivotally mounted plow mulcher connected to the plow frame through hinged arms. A plow mulcher frame is carried on the outer ends of the hinged arm and may be moved between raised and lowered positions by operation of an overcenter spring arrangement, hydraulic cylinder and cable arrangement, or a hydraulic cylinder extending between the plow frame and the outer hinged arm portion. A cushioning spring may be provided for the hydraulic cylinder to yieldably permit raising of the mulcher frame without contracting the hydraulic cylinder. The mulcher and the plow may be operated from a common hydraulic power source through separate hydraulic cylinders connected together such that the mulcher is raised and lowered first due to its lower power requirements. Unlimited adjustability is provided in the mulcher structure to position the mulcher as desired relative to the plow.
