Abstract: Shallow angle furrows between crop beds are reshaped and cleaned in one pass using a tractor-towed implement having angularly even-spaced cutter blades mounted in tiers on drums for rotation about generally vertical axes, perpendicular to the furrow walls on opposing, angularly adjustable decks. The blades of the lower tier are angled to cut into the wall material laterally, parallel to the wall slope, without destroying the root structure of protective sod covering. The cut material is lifted up to the upper tier blades which are offset and lagged so as to eject the cut material up and beyond the furrow wall edges following cutting, in one continuous operation. Plates and pivotal deflectors mounted at the edges of the decks, direct the discharge of cut material. A bell crank and pivotal linkage provides for hydraulically assisted raising and lowering of the apparatus from and into ground contact.

The knives of each pair orbit in the same direction and cooperate as the blades of shears to loosen and comminute the ground. The holders are driven by a motor and the cutting edges of the knives constitute helices extending counter to the direction of orbital movement of the respective knives.

Abstract: The soil loosening device has at least one, preferably two journals protruding downwardly from a supporting body, which are driven to a pivotal motion along a limited angle. Tine-like soil loosening tool members in bifurcate arrangement, to be driven along a circle segment, are mounted on the journals.

Particularly, there is provided a crank shaft which drives a toothed rack member to an oscillating motion. Gear wheels connected to the journals mesh with the toothed rack member. Accordingly the expenditure in manufacturing the device is low and the device has a high resistance to wear. The driving unit of the device may be attached to the supporting body in different angular positions by means of a coupling device.

Abstract: An agricultural machine with a frame on which tool rotors are mounted on upright shafts in a row extending across the direction in which the machine travels. The rotors are driven by a horizontal driveshaft that is segmented and interlocked by couplings. Each segment of the driveshaft is a component of one of the angular gears that drive the tool rotors. The horizontal driveshaft is coupled, through a coupling device that is inside the housing of a main train mounted on the frame, with the output gearwheel of the main train and hence driven by it. Guides for aligning the central axis of the components of the driveshaft with the center line of the output gearwheel of the main train are positioned in a known way at least between the main train and the gears of a tool rotor that are immediately adjacent to it. The coupling device has a coupling component that is rigidly attached to the components of the driveshaft that extend into the main train.

A bevel pinion is rotatable around the lower end of such fixed shaft and is fastened by adhesively secured pins to the top of one of the spur pinions, each of which is welded to the upper end of a rotary shaft carrying the corresponding soil working member. Blades are provided adjacent the bevel pinion and nearby spur pinions to distribute lubricant to such pinions. One lifts lubricant to the intermeshing spur pinions and another blade further guides same to the bevel pinion.

The frame portion comprises three spaced apart sheet walls that define an upper chamber and a lower chamber. Driving means, including meshed pinion gears in the upper chamber and bearing housings in the lower chamber, receive and support upwardly extending shafts of soil working members. The soil working members have downwardly extending tools that are rotated by the pinions and their shafts are journalled in bearings held between the upper and lower walls of the lower chamber. The upper wall of the lower chamber forms the lower wall of the upper chamber. All three walls are bent at their front and rear sides to provide portions with rims that are joined to one another by bolt fastenings.

The tine has an operative portion that is curved from its holder so that the majority of that portion co-extends with the center line of the shaft. Each cultivating member can have a single tine that is fastened to the lower shaft end and a supporting part on that end has a face that cooperates with an opposing face of a fastening tine part and a centering member ensures proper fit. The members are removable as separate units together with their bearings, housings, gears and connections, from the top of the hollow frame portion or at least from above the bottom of the frame portion.

Abstract: A cultivating implement has an elongated frame portion that mounts a row of rotors that rotate about upwardly extending axes. At the lateral sides of the frame portion, screening plates are positioned to arrest the lateral displacement of soil being worked. Each screen is substantially vertical with its front part being linked to an overlying frame structure and rear roller that supports the frame portion. Parallelogram links arranged one above the other interconnect each plate with a support part of the structure. The links extend forwardly from the plate from pivot connections to further pivot connections. The connections define horizontal transverse axes that allow the plate to move up and down as it rides along the ground. The front connections are resilient members that allow some lateral deflection of the plate. The plate has an upper, rear bent over portion that allows entry of a supporting roller arm to a pivot connection to the supporting frame structure.

The common driving shaft is located below the imput shaft and both shafts extend transverse to the direction of travel. The change speed gear includes interchangeable pinions housed within a box at the lateral side of the frame portion.
