Abstract: A depth control includes an actuator tube connected for movement with the rockshaft and having a threaded crank supported on the forward end of the tube. A valve operator bracket is slidably and nonrotatably received over the tube and includes a threaded portion engaging the crank threads to positively locate the bracket relative to the tube. The bracket carries a plunger which, as the rockshaft lowers the implement to the working position, is moved into contact with a valve actuator to close a valve and prevent further lowering of the implement. One turn of the crank gives the same positive movement along the tube each time the depth setting is adjusted so that working depth can be set very accurately and easily.

Abstract: A repositioning mechanism for an agricultural implement. The mechanism has an adjusting rod with a length, a receptacle for the adjusting rod, cooperating structure on the adjusting rod and receptacle for relatively moving the adjusting rod and receptacle lengthwise of the adjusting rod as an incident of the adjusting rod being rotated about its length, structure on the receptacle for mounting an agricultural implement so that the agricultural implement moves with the receptacle, an operating handle, and structure for attaching the operating handle to the adjusting rod to facilitate rotation of the adjusting rod about its length by manipulation of the operating handle. The attaching structure, in one form, is a pin on one of the operating handle and adjusting rod and a slot on the other of the operating handle and adjusting rod, to receive the pin with the operating handle and adjusting rod in an operative position.

Abstract: An agricultural earth working system including a vertically adjustable deep tillage tool in tandem with a V-shaped sweep blade tool, the system being mounted on a field traversable frame and adapted to be drawn through the field by a conventional farming tractor. A disk is positioned in front of a shank for the sweep blade tool. The system cuts roots of weeds with the sweep blade and at the same time deep shatters or cultivates the soil with the deep tillage tool in such a manner that very little of the field surface is disturbed, so as to retain stubble cover and prevent erosion, yet destroying the weeds and sufficiently working the ground beneath the surface, especially with the deep tillage tool to enhance water absorption.

Abstract: A tool, and method of utilization, for achieving fine vertical adjustment of a crop divider pivotally mounted on the front of a crop header. The tool includes an inverted J-shaped support member adapted for attachment to a frame member of the crop header. Rotatably secured to the support member is an elongated screw member to which is threadably mounted for axial movement an annular ring. The tool is mounted such that a coarse adjusting chain, which normally extends between the crop row divider and crop header, passes through the annular ring. By rotating the elongated screw, the ring moves axially in a direction generally perpendicular to the normal orientation of the chain to alter its effective length, causing the crop row divider to pivot about its mounting and thereby adjust its vertical position relative to the ground.

Abstract: An apparatus for soil working, consisting of a frame (1) drawn over the ground by a vehicle, a first roller (7) mounted rotatably in the frame (1), extending transversely to the travelling direction, a second rotatably supported roller (19) arranged parallel to and behind the first roller (7) and driven thereby through a transmission (17), and two or more rows of soil working members (6) fixed to the frame, wherein the first roller (7) extends between two rows of soil working members (6), and is mounted adjustably in height an securably with respect to the frame (1), the second roller (19) being coupled either to the frame (1) or to the first roller (7) by two or more vertically moveable swing arms (20), so effectuating a precise pressure on the ground of the first (1) or alternatively the second roller (19) independently of one another, and also by maintaining an exact setting of the soil working members (6) at a specific level.

Abstract: This invention relates to an attachment for conventional planters that will convert them to ridge-till planters at reasonable costs. It consists of a pair of laterally spaced vertical mounting bars, fastened suitably at their upper end to the parallel linkage of a planter, extending downward to connect pivotally to the rearward end of a horizontal L-shaped parallel linkage, whose forward ends connect pivotally to the horizontal frame of this invention called the ridgemate. At the forward end of the horizontal frame is a drum wheel that runs on top of a ridge and gives constant height to the horizontal support frame. To the rear of the drum wheel is a pair of disk openers, adjusted in depth by a tubular screw arrangement. Following closely and to the rear of the disk openers is a sweep to widen and further clean off the ridge. The sweep also is adjusted in its operating depth by a tubular screw arrangement.

Abstract: An attachment for a minimum tillage planter which is mounted forwardly of the planting shoe for removing residue from in front of such planting apparatus for the purpose of allowing consistency in the making of a trench and for the depositing of seeds therein in a consistent manner. The attachment generally includes a first center flat disc having a circular structure attached thereto for controlling the depth at which the planter rides above the ground. A pair of additional discs are mounted on each side of the depth control structure and on each side of the center flat disc. These additional discs are convex on the side adjacent to the first disc and concave on the other side thereof. The position of the additional discs are such that they do not extend into the ground as far as the first disc whereby the first disc will hold residue, such as a corn stalk, while the other discs which are higher will cut the residue off and then throw it to one side or the other.

Abstract: A soil cultivating machine comprises two transverse rows of fixed tines and three transversely extending rollers. The front roller has discs which cut parallel slits in the soil. The two following rollers have transversely extending releasable blades mounted on angle-irons which form shallow V's pointed in the direction of the rollers' rotation and which are twisted about 90.degree. from their outboard ends to their centers. The rollers are drivingly interconnected by a chain transmission so that the middle roller rotates slower than the other two and the rear roller rotates faster than it would if freely rotating on the ground. The tines are in rows between the rollers and their depth of soil penetration relative to the underlying soil is adjustable. The rollers are mounted on a generally horizontal framework which is adjustable, however, so it can be inclined slightly either forward or aft to increase or decrease the penetration of the front roller's discs.

Abstract: A soil cultivating machine has a frame portion extending transversely of the intended direction of operative travel and a row of cultivating members on that portion are rotatable about upwardly extending shafts. Behind the cultivating members there is a ground-engaging support roller pivotally connected with the frame portion by means of supporting arms. A mechanism, including a screw spindle or an hydraulic ram is provided for adjusting the roller in a direction of height to vary the working level and a locking device for fixing the roller against pivotal movement relative to the frame portion is also included. The locking device includes two parts that can be clamped against one another with relatively co-operating toothings interengaged. A resilient device on a rod of the mechanism is provided to allow relative movement between the co-operating toothings at the time of clamping the parts together.

Abstract: This invention consists of a vehicle for handling multi-furrow ploughs, which are very heavy and are equipped with only one wheel in the rear, when not attached to a tractor during operation. It consists of a two wheeled cart provided with two hooks attached to the main body of the cart, by means of which the front end of the plough is picked up and held, and a central arm for pulling the cart which is swivably attached to the main body. A ratchet operated cylinder having two oppositely threaded screws, one going in or out at each end simultaneously, is swivably attached to the arm and to the main body of the cart, so that turning the ratchet in one direction expands the distance between the screw ends thus lowering the hook towards/the ground to pick up the front end of the plough, and turning it in the opposite direction reduces that distance and lifts the hooks and front end of the plough to make it mobile.
