Abstract: A scraper assembly of an agricultural row unit includes an inner scraper configured to engage an inner surface of a disc. The scraper assembly also includes a biasing member engaged with the inner scraper and configured to urge the inner scraper toward the inner surface of the disc. In addition, the inner scraper has an engagement feature configured to contact an outer scraper to block translational movement of the inner scraper relative to a frame of the agricultural row unit.

Abstract: A tractor mounted tiller/cultivator system that includes right and left swing arms pivotally attached to tractor chassis, right and left cutting head assemblies mounted on the swing arms, each including a right disc motor driving a rotary disc mounted on a distal portion of the swing arm and operatively coupled to the motor. Ground-engaging cultivation wheels surround the rotary disc, and an annular guard prevents unwanted contact of the wheels with vines or trunks of vines and trees. A drive mechanism lowers and raises the swing arms to put the cultivation wheels into engagement and disengagement with ground and to rotate said swing arms about their longitudinal axes. User controls operatively connected to the swing arms, cutting head assemblies, and drive mechanisms enable a user to finely tune the movement of the cutting heads into and out from rows of trees or vines.

Abstract: Agricultural apparatus to be driven by a tractor comprises a main frame attachable to the rear end of the tractor, a pair of ground-engaging wheels carried on the opposite ends of the main frame, a pair of rotary-driven agricultural units mounted on opposite sides of the main frame along a common axis, and a third rotary-driven agricultural unit mounted on the main frame centrally between the pair of units and rearwardly of their common axis. The three rotary-driven agricultural units such as rotary tillers, are each independently mounted to the main frame by a separate 3-point connection, permitting each to be float upwardly or downwardly with respect to the ground.

Abstract: A frame carries two transverse digger shafts each having a plurality of diggers mounted thereon in spaced apart relationship such that the diggers form independent furrows. The frame is supported on wheels on a single axis between the two digger shafts and it tiltable on this axis substantially independently of the three point hitch by virtue of a pair of pivoted connections between the hitch and the frame. A longitudinal tilt arm extends from an elevated position over the frame and is connected near its forward end by a resilient member to the hitch or to a selected attachment point on a rigid telescoping member also extending between the tilt arm and hitch. The tilt of the frame is also biased by placement of the wheel frame axis slightly to the rear of the frame's center of gravity. The digger shafts are connected to the drive for opposite relative rotation with the rear shaft rotating rearwardly whereby its diggers apply a retarding force to the frame and stabilize the frame on the frame wheel axis.

Abstract: A soil working machine has elongated carriers that extend transverse to the direction of travel, one behind the other. Eccentric mechanisms are attached to each carrier to move tools depending from the carriers, back and forth in directions parallel to the direction of travel. The eccentrics have upper supports connected with resilient controls and lower supports of unequal lengths so that the tools work different paths. A front levelling member is connected to the frame via a parallelogram linkage and the rear carrier has a row of tines. A supporting roller is connected to the frame by arms each of which has two portions. The portions can be pivoted or slid towards and away from one another so that the roller is also moved towards and away from the carriers. Also, the arms with roller are vertically adjustable and fixable in position.

Abstract: An implement has rows of tines on carrier supports that are elongated and extend transverse to the direction of travel. A transmission shaft with pairs of eccentrics is positioned between the supports and connected to move the tines of the supports to and fro in relatively opposite directions. The eccentrics are in pairs and interconnected to the frame by adjustable links that control the operative movements of the tines, those movements being in the direction of travel. A pulverizing member is pivoted to the rear carrier support to move with same and a front soil levelling member with strip-shaped members is positioned in front of the tines. Preferably, a supporting roller is connected to the frame at the rear of the pulverizing member.

Abstract: An implement has a forward row of soil working members that have flat blades and the blades are periodically raised and lowered to initially coarsely break the soil with pivotal motions induced by respective eccentrics mounted on a horizontal shaft. The members have respective polygonal linkage connections to the frame. Further soil working members that include elongated bars with tines are moved to and fro to work the upper layer of coarsely broken soil. The bars are pivoted about upwardly extending pivots and an eccentric reciprocates the bars in relative opposite directions. A trailing roller is linked to the bars and to the frame supporting the bladed members. The bars and roller are interconnected to the frame sides by parallelogram linkages that can be fixed to regulate the working depths of the blades and the tines.

Abstract: A self propelled disk harrow having four gangs of disc members attached thereto which are rotated to propel the disk harrow and to thereby till the soil. Wheels are provided for allowing the disk harrow to travel on public roads and to aid in propelling the disk harrow. When the disc members extend too far into the soil or otherwise become ineffective in propelling the disk harrow, such as because of wet or sandy soil, the weight of the disk harrow transfers to the wheels and the wheels tend to primarily propel the disk harrow.

Abstract: A cultivating implement has an elongated frame portion and soil working members journalled in the frame portion to rotate about upwardly extending axes. Each soil working member has a single downwardly extending tine that is spaced from a shaft that defines the corresponding axis of rotation. The upper ends of the shafts of the members are secured to pinion gears and the gears of neighboring shafts are meshed with one another so that a power take off connection to a central pinion drives all of the pinions and adjacent soil working members rotate in relatively opposite directions. The members are staggered in two straight transverse rows so that their axes of rotation are arranged at the corners of an imaginary zig-zag line when the implement is viewed in plan and the members of a leading row are rotated in common in a direction opposite from those members of a rear row. The tines of the members in each row are preferably orientated in the same direction.

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.

Abstract: Disclosed is a tilling apparatus characterized by a regulating drive connection between the towing tractor drive axle and the tiller shaft, the tiller tines having a modified arcuate configuration which provide a pocketed, rather than a furrowed or channeled, tilling depth profile.
