The implement includes a wheeled frame operably supporting at least three longitudinally spaced tillage tool assemblies which first chops crop surface residue, then aggressively lifts and redistributes the chopped surface crop residue and breaks up the soil surface crust, and then levels the soil so that the soil surface is substantially smooth and ready for planting, all in a single-pass without tilling the soil at seed planting depths.

Abstract: A drawbar having a boom with at least two pivotally connected sections which in a field position extend generally transversely of the direction in which the draw is drawn. Each section carries at least one first soil working device and at least one other second soil working device is trailed behind said first soil working device. The sections are pivotable in unison, about a horizontal axis transverse to the direction in which the drawbar is drawn, from said field position to a non-working position. In the non-working position the soil working devices are raised in order that the sections can be pivoted relatively to each other to a folded, transport position.

Abstract: A tine mounting arrangement for a harrow provides a transverse elongate support member with a plurality of stub shafts extending outwardly therefrom in the same horizontal plane at an angle of 45.degree.. Each stub shaft carries a pair of spring tines with the springs wrapped around the shaft and an inclined portion of the tine extending forwardly from the angled shaft and therefore at an angle to the transverse support member. Two such members can be mounted on pivot arms to provide a transverse reciprocating working action of the tines. This harrow element can be mounted upon support arms pivoted from a draw bar and carried on ground wheels which may be simple depth wheels or may form packer wheels. In an alternative arrangement the packer wheels and harrow element are mounted on a subframe which can be reversed so that the packers operate in advance of the harrow element.

Abstract: A cultivating implement has one or more forward cultivating rotors that are driven to work the top soil. During this working, stones and debris are unearthed. At the rear of the cultivating members, one or more rows of soil working members are moved through the soil and these members are soil engaging members with edges that contact the stones and push the stones down into the subsoil. The soil engaging members can be discs with edges having projections and the discs can be driven to rotate in the same or opposite direction as the rotor. Alternatively, the soil engaging members can be bars that extend down into the soil. In either case, a sieve of rods or bars can be positioned behind the rotor to allow fine soil to pass while stones are guided downwardly in front of the fine soil. The lower ends of the soil engaging members can be interconnected with a horizontal shaft on which the discs are mounted. A protective hood overlies the rotor as well as the soil engaging discs or bars.
