Abstract
Abstract In a soil cultivating implement of the kind which comprises a row of power-rotatable soil working members 3 that extends substantially horizontally perpendicular to the intended direction of operative travel (A) of the implement, a toothed (18) packer roller 14 lies behind the soil working members 3 and is associated with a plurality of flat oblong scrapers 19 whose leading scraping edges lie very close to the curved surface of a cylinder 15 of the roller 14 between successive groups of the teeth 18 in positions which are behind the roller 14 relative to the direction A and at a level beneath that of the intended axis of rotation a of the roller 14. The scrapers 19 are connected in groups by arms 23 to a tubular carrier 26 and a lever mechanism comprising upper and lower lugs 27 at the opposite ends of the carrier 26 can be turned angularly about aligned pivot pins 28 by manually operable screw-threaded spindles 30 to turn at least half, and preferbly all, of the scrapers 19, in common, about that axis 28 to move all those scrapers 19 either closer to, or further away from, the curved surface 15 of the roller 14. This construction greatly facilitates simultaneous adjustment of all of the scrapers 19 into an optimum soil-shedding position relative to the cylinder 15 of the roller 14. Several other constructions and arrangements of the scrapers and lever mechanisms are described and illustrated and, in particular, a construction in which each scraper is elongate and of arcuately curved cross-section, its leading end being in the form of a convex rim which matches the curvature of the roller cylinder 15 where that rim is in very close proximity to that surface.
