| A soil manipulation device is provided for closing a groove in soil formed by a soil tiller shank. The device includes a frame connected to a rear portion of the tiller shank and a pair of rotatable coulter blades mounted on the frame for engaging soil behind the tiller shank. The coulter blades are positioned on opposite sides of the groove so as to close the groove in the soil behind the tiller shank. The coulter blades are selectively movable and positionable in directions toward and away from each other so as to vary the distance between the coulter blades. The coulter blades also are selectively movable and positionable in a substantially vertical direction with respect to the frame, so as to permit variation in depth of coulter blade penetration into the soil. The coulter blades have side surfaces which are selectively movable and positionable from orientations which are substantially in parallel with the groove to orientations which are out of parallel with the groove, so as to variably manipulate soil on opposite sides of the groove. | ||||||
| 92 | Ground leveler attachment for a ground working device | US523152 | 1995-09-05 | US5595249A | 1997-01-21 | Dan P. Steinberger; Jack Oberlander |
| A ground leveler attachment for a ground working device comprises a bracket fastened to a shank supporting a ground breaking tool, a carrier arm connected to the bracket, a pair of leg supports in pivotal contact with the carrier arm, a pair of springs biasing the legs supports into pivotal contact with the carrier arm, a pair of leg members extending from the leg supports, and a pair of levelers rotatably mounted upon the leg members and biased into a ground engagement position by the springs. The levelers independently and resiliently retract upon contact with a relatively immoveable object or objects to avoid being broken off from the leg members or severely damaged beyond usefulness. | ||||||
| 93 | Bridge hitch type frame | US720418 | 1985-04-05 | US4625809A | 1986-12-02 | Gary Moynihan |
| A plow and disc combination machine which utilizes a bridge hitch type frame which is built in the same order as a highway bridge which enables the plow to have clearance so that a disc gang mounted under it and movable by hydraulics can be raised or lowered on the move. The fact that a bridge truss structure is utilized in the frame allows the discs to be movable over a wide vertical range and allows the subsoiler plow shanks to be used in the ground at maximum depth without the usage of the disc blades. The discs can also be lowered to cut material such as corn stalks as the plow is used. | ||||||
| 94 | Tillage implement and improved gang assembly therefor | US358121 | 1982-03-15 | US4492272A | 1985-01-08 | Thomas C. Jensen |
| A mulch tiller or similar implement having a rigid frame supporting a plurality of forward trash-sizing gang assemblies and rearward plow tools. Spring brackets rockably support the gang asemblies for independent vertical movement with respect to the frame and maintain a generally constant down pressure of the gangs against the soil. The frame includes diagonal beam structure and a lower subframe assembly for compact shipping, good draft load distribution and underframe clearance. Common depth control, main frame and hitch components are utilized for implements of varying widths to reduce cost. | ||||||
| 95 | Soil working machine | US919454 | 1978-06-27 | US4243104A | 1981-01-06 | Sandor Sipos; Sandor Varga; Imre Hali |
| A soil cultivating machine has a pair of frame units inclined rearwardly divergently to each other, each frame unit having a respective tool-holding shaft. Each shaft is associated with two tool-holding bars, one in front of the shaft and one behind it. The bars carry deep-tilling implements, while the shafts carry disc-like tools. There is a prescribed numerical relationship between the depth of tilling by these implements and the distance, measured in a direction parallel with the direction of advance of the machine, between a given implement and the associated disc-like tool. There is a further prescribed numeral relationship between this distance and the velocity of advance of the machine. | ||||||
| 96 | Soil cultivating implements | US806670 | 1977-06-15 | US4191258A | 1980-03-04 | Cornelis van der Lely |
| An implement attachable to the lifting links of a tractor has at least one, preferably two, rows of tines fixed to respective transverse frame beams. Between the rows of fixed tines, a supporting roller is pivoted to the frame. The roller can be adjusted relative to the frame to regulate the working depth of the first row of tines. An elongated soil working member is connected to the rear tined beam by a parallelogram linkage and a drive transmission, including at least one eccentric, is connected to upwardly extending support standards to reciprocate the working member in up and down directions so that lumps of soil are crumbled and levelled. The parallelogram linkage is resiliently connected or associated with the frame by opposing springs that permit reciprocal movements of the working member relative to the rear row of tines. The eccentric can be meshed pinions in a housing that are rotated by a drive shaft and each pinion weighted to be out of phase with the other by 180.degree.. Various ground engaging bottoms can be detachably secured to a carrier depending on the soil condition and intended use. | ||||||
| 97 | Adjustable height soil conditioner with frame extending rearwardly from cultivating implement | US507749 | 1974-09-20 | US3935906A | 1976-02-03 | Archie E. Neal; Paul Moore |
| A soil conditioner for use in combination with a cultivating implement drawn behind a tractor to break up the soil and leave a prepared seedbed in a single operation. The conditioner is mounted to a framework extending rearwardly behind the cultivator. It comprises a set of reels each mounted to the framework for free rotation about a transverse axis. Two sets of axial blade members are provided about each reel. The blades are equiangularly spaced about the axis and are arranged so that each blade of one set is angularly spaced midway between adjacent blades of the other set. The first set of blades include ground-engaging edges spaced a first radius from the axis. The corresponding edges of the remaining set of blades are spaced a second radius from the axis that is less than the first radius. The different radii of the two sets of blades enable the conditioner to be towed through a field, with the freely-rotating blades breaking up clods of dirt left by the cultivator, without the blades becoming clogged with dirt. The conditioner also includes an adjustment structure for elevationally adjusting the blade edges relative to the cultivator. This adjustment structure includes adjustment brackets each connecting two portions of the soil conditioner frame. Each of these brackets is provided with a plurality of apertures. These apertures are selectively aligned with a set of corresponding apertures on one of the two portions of the soil conditioner frame. By placing bolts through the aligned apertures, the elevation of the blade edges is selectively adjusted. | ||||||
