Abstract: A cultivator-material dispensing combination includes a soil-working member that rotates about a horizontal axis forwardly, relative to the direction of travel, to displace soil over the top of that member to a screening at the rear thereof. A seed dispensing hopper has conduits that are supported on a hood that overlies the member and extends to the rear thereof. Material is metered from the hopper through outlets at the conduits' lower rear sides. Drive to the hopper is via a one-way transmission that is driven by a rear roller only when the combination moves forwardly. A further roller can be positioned to the rear of the first mentioned roller and a fertilizer hopper feed also driven to dispense material to the worked soil.

Abstract: A cultivating implement has an elongated frame portion with soil working tines rotatably mounted along the length of the frame portion. The implement is supported, at least in part, by a leading member and a rear member each of which bear on the ground in advance and to the rear of the soil working tines. The supporting members can be wheels, rollers, a row of rods, levelling bars or combinations thereof which are interconnected by at least one linkage. Each supporting member has a respective carrier that is pivoted to a strip or pair of strips secured to the frame portion. The carriers include upwardly extending arms or plates with holes at different levels that receive pins and the pins interconnect the upper portions of the carriers to an adjustable connecting member. When one supporting member is displaced upwardly or downwardly, the other member is displaced in an opposite direction.

Each tool has a central hub and radial arms with a tine secured at the outer end of each radial arm. The tools of each member are spaced from one another around their respective shaft by about 50 centimeters or less and are rotatable about axes inclined to that shaft by about 5.degree. to 10.degree.. Upon rotation of the rotor member, the tines of the tools contact the ground to rotate the tools. The tines have elongated, upper fastening portions that are angled to lower, elongated soil working portions. The cross-sections of the fastening portions are polygonal and held in matching bores of holders at the outer ends of the radial arms. A support roller is connected to the rotor members to regulate the working depths of the tines.

Each soil working member has arms and at the ends of the arms, tined soil working tools are mounted for free rotation about respective upwardly extending axes. Drive to the members is accomplished via coaxial shafts one of which is geared to bevel gears and the shafts extend transverse to the direction of travel. The two shafts include an upper input shaft and a lower drive shaft that are interconnected via a change speed gear.

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.
