Abstract: A row unit for a work vehicle includes a row unit frame with a closer frame. The closer frame defines a longitudinal axis and a transverse axis. The closer frame is supported for rotational movement about a substantially vertical steering axis to vary a turning angle between the longitudinal axis the vehicle longitudinal axis. The row unit includes a closer implement assembly with first and second closer implements and a walking beam construction. The first and second closer implements are attached to opposite areas of the walking beam construction. The walking beam construction is rotationally attached to the closer frame to support rotation of the closer implement assembly about the transverse axis. The first and second closer implements are configured to move ground material into a ground opening from opposites sides as the work vehicle moves across the field.

Abstract: A planting system including a plurality of seeding row assemblies, each having components maintained at a controlled elevation.

Abstract: A trash farming implement is provided with a plurality of tillage assemblies on an implement, each tillage assembly having a tillage disc arranged to rotate about an axis which is inclined slightly from the vertical both in end elevation and in side elevation so that it slopes upwardly and forwardly in the direction of travel, and also a soil replacing disc which has an axis of rotation which is nearly horizontal but slopes upwardly towards the tillage disc to which it is adjacent, the disc being so located that a furrow cut by the tillage disc will be filled by replacement of the lifted soil to its original position.

Abstract: A subsoil implement is disclosed that utilizes a horizontally rotatable disc that is moved beneath the surface of the ground for the purpose of cultivating or for producing a sub-surface bed for placing flowable material such as seed or soil treating gas along the prepared bed. A hollow delivery tube or rigid shaft leads to the disc and rotates about an axis defined by a bearing directly adjacent the disc. Seed or chemicals may be directed through the hollow tube form to the ground surface below the cultivator disc. Therefore, cultivating, planting or soil treatment can be accomplished with minimal effort. Trash clearing elements are provided on the rotating tube or shaft to eliminate trash build-up and minimize disruption of the soil surface.

Abstract: A cultivating implement has rows of tined soil working members that are freely rotatable about upwardly extending shafts. Each soil working member has tines positioned around the shaft which defines its axis of rotation. At the lower end of the shaft, a channelled feed member is attached and the shaft is hollow. Material from a container is dispensed from the container through the shaft and the feed member via a port to the ground being worked by the tines. The feed member is elongated and extends down, generally parallel to the tines of the corresponding soil working member which are mounted on circular plate supports. A further soil working member, preferably a supporting roller, is mounted behind the rows of soil working members.

Abstract: A cultivating implement has rows of rotatable soil working cultivating members that are mounted on beams extending transverse to the direction of travel, one behind the other. The members rotate about upwardly extending axes and can be positioned along the beams to cooperate with one another and work soil between rows of plants. Assemblies of crumbler-rollers are secured to the frame and positioned to engage soil worked by the cultivating members but avoid the plant rows. Each assembly is secured by a support arm adjustably settable along the length of a beam at the rear of the frame. Each assembly is a pair or two rollers journalled on a common shaft and each roller has two supports, one of which is movable along the shaft to and from the other to adjust the width of the roller. Each support mounts bars that form the periphery of the roller.

Abstract: An implement preferably has elongated, stationary beams that extend horizontally transverse to the normal direction of travel. Staggered soil cultivating rotors are fastened to the beams at spaced apart locations and are ground driven to work closely adjacent strips of soil or a single broad path. Each rotor is freely rotatable about an upwardly extending shaft and has downwardly extending soil working members, such as tines, with lower active portions. Each active portion can have a lower outwardly directed part that, during rotation, describes a circle having a radius about equal to or less than the length of the active portion. The outwardly directed tine part increases ground contact and improves rotation. The rotors can be mounted in pairs; the rotors of each pair being angled from the vertical so that they rotate in opposite directions from one another.

Abstract: A cultivator implement has a row of freely rotatable soil working members connected to a transverse frame beam by brackets. The members each have a stub shaft secured to an inclined web of a corresponding bracket so that the axis of rotation of each member is inclined to the vertical. Pairs of downwardly extending tines on support plates contact the ground and rotate the members. Between adjacent rotatable members, a cultivator tine is deflectably secured to the beam via an integral spring coil assembly. The cultivator tine is located non-centrally between rotary members and each tine is curved so that its lower tip extends forwardly. A soil working roller is positioned to the rear of the rotary members and is vertically adjustable on arms connected to the ends of the beam.

Abstract: A cultivator implement has two rows of freely rotatable, tined soil-working members connected to leading and rear transverse frame beams by respective brackets or plates. Each rotatable member is mounted for rotation on a corresponding stub shaft that defines its axis of rotation, which is inclined to the vertical. Pairs of downwardly extending tines that are secured in respective holders around the axis of rotation, contact the ground and rotate each member. A first row of rotatable members have axes inclined to one side of the vertical and a second row of rotatable members have axes inclined to the opposite side of the vertical. A fixed cultivator tine is deflectably secured to the beams via an integral spring coil assembly. The cultivator tines are positioned non centrally between adjacent rotary members and each tine is curved so that its lower tip extends forwardly.

Abstract: A combination implement has a leading cultivator with fixed tines and a rear rotary harrow with driven soil working tined members. The cultivator has side ground wheels with vertical adjusting means that controls the working depths of the fixed tines. The harrow has a trailing roller that is interconnected to the harrow frame with arms that also have an adjustment feature so that the working depths of the harrow's tined members can be regulated. The cultivator and harrow are linked to one another by a parallelogram linkage so that they can be disconnected from one another and individually connected to the three point lift of a prime mover. When the combination is assembled, a suspended drive shaft of the harrow's driving system is passed through the cultivator and connected to the p.t.o. of the prime mover.
