The frame portion extends transverse to the direction of implement travel and a support beam with further soil working members is positioned at the rear of the frame portion. The support beam is interconnected to the frame portion by arms and at least one, preferably two, pivot points on each arm enable adjustments of the level of the support beam with the further soil working members to be effected. One pivot point is at the rear portion of each arm and includes locking and pivot bolts. A second pivot point, again including locking and pivot bolts, connects the forward portion of each arm to the frame portion.

Abstract: An implement has an elongated frame that extends transverse to the direction of travel and soil-working members rotatably mounted on a portion of the frame that depends from spaced apart, forward and rear frame beams. A coupling assembly having coupling points for auxiliary implements is pivoted to the forward frame beam by two beam members that extend rearwardly and rest on top of the rear frame beam to limit the downward movement of the assembly when the implement is raised. The rear ends of the beam members are connected to a tubular beam and further beams extend rearward from the tubular beam. A transverse beam interconnects the further beams centrally thereof and coupling points such as hooks are adjustably connected to plates that depend from the further beams. A central coupling point is fastened to the transverse beam and the further beams are adjustable to vary the width of the assembly.

Abstract: A homogenizing mechanism for a manure slurry in combination with a supply container and blades adapted to penetrate about fifteen centimeters under the soil surface for injecting manure into the soil by an injection pipe carried by the blade. The mechanism is disposed between container and the injection outlet so that the injected slurry must pass therethrough. An air displacement pump selectively places the container under pressure (up to about one atmosphere) or vacuum for moving the slurry out of or into the container, respectively. The homogenizing mechanism has a substantially cylindrical casing with an inlet from the container on one end and an outlet leading to the injector at the other end. The inlet may be a conduit or an open end of a casing mounted in part within the container.

Abstract: A cultivating implement has an elongated, rotatable cultivating member that is driven to rotate about a horizontal axis. The cultivating member has a central support that defines its axis of rotation and the support is polygonal in cross-section with tines resiliently fastened to each side along the length of the support. Each tine has an outer, arcuately curved portion that is fastened to an inner portion through a coil having turns located to the rear and adjacent a succeeding side relative to the direction of its rotation. The outer portion has a replaceable blade at its outer free end and different blades can be secured to that free end. A further row of fixed but resilient tines is connected to the frame in front of the rotatable member and an additional row of resilient tines is pivoted to the frame, at the rear of the rotatable member.

Abstract: A cultivating implement has a row of driven rotor members that rotate about corresponding upwardly extending shafts, the rotor members have two or three support arms and a freely rotatable tool on the outer arm ends. 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.

Abstract: An implement has a row of tined motors that work a broad path of soil. Immediately in front of the rotors is a soil displacing elongated bar that is held to penetrate and raise a shallow layer of soil which is thereafter deposited immediately in front of the working tines. The bar extends parallel to the row of rotors and has a flat bottom that slightly compresses the ground from which the layer of soil is being displaced. The bar can be raised or lowered on supports interconnected to the frame. In front of the bar, a V-shaped guide can be connected to smooth the soil engaged by wheels of the prime mover. A rear roller can be positioned to further level the layer of soil that has been worked by the counter rotating rotors so that a seed bed can be finally prepared in one pass.

The soil working members have tines, the inner ends of which are secured in recesses of plates near the axes of rotation of the working members. Each tine has an inner curved part and an elongated support portion to which downwardly, inclined soil working portions are integrally joined. The tines are free to deflect from their connections and neighboring soil working member tines work overlapping and/or adjoining strips of soil. The paths traced by the revolving tines spans a diameter that exceeds the width of two neighboring pinion gears.

Abstract: An implement, such as a cultivator with rotary tools, has a drive from an imput shaft to an output shaft via a change speed gear assembly. A driving shaft is connected to the imput and the driving shaft rotates a side shaft, which can be the output shaft. A corresponding set of different sized gear wheels are mounted on both the driving shaft and the side shaft. The gear wheels of one set are meshed with respective gear wheels of the other set and drive is transmitted through any one pair of meshed gear wheels. Either one of the driving or side shafts can be displaced with respect to the corresponding gear wheel set and external splines on that one shaft selectively engage the internal splines of any one of the gear wheels to selectively establish a gear transmission ratio that rotates the tools at predetermined speeds.

Abstract: A rotary harrow has a plurality of soil working members rotatably mounted on upwardly extending shafts and the shafts are journalled in an elongated frame portion that extends transverse to the direction of travel.
