Abstract
A cultivator comprises an array of laterally-spaced soil-inversion discs having their centers arranged in a substantially horizontal line lying at not more than 30.degree. to a transverse plane of the cultivator and being mounted for rotation about individual axes which are equally inclined to the vertical and, when viewed in plan, also to the longitudinal plane of the cultivator.
Claims15
A cultivator having an array of laterally-spaced soil-inverting units, each soil-inverting unit comprising a plough-type body having a plowshare and a mouldboard to begin inversion of laterally spaced strips of soil, a respective concave ground-driven soil-inversion disc spaced laterally and rearwardly from each said mouldboards working at a similar depth to the plough-type body and inclined to vertical and when viewed in plan, also to a longitudinal plane of each unit so as, in operation, to lift both deposited soil partially inverted by the plough-type body and the unmoved strip of soil beneath the deposited soil, and respective generally planar deflector means following the disc and arranged to complete the soil-inversion process across the entire width of soil defined by said array of units.
