| 141 | Tiller and Bed Former With Dual Belt Drive | US13563515 | 2012-07-31 | US20140034340A1 | 2014-02-06 | Eugene W. Walker, JR. |
| A tiller (100) configured to be pulled by a tractor includes a support structure (110) comprising a hitch assembly (112), a rotor housing (120), and a rear support (114). A rotary tiller assembly (150) is rotatably mounted in the rotor housing. A drive assembly (130) includes a gear box that receives power from a power takeoff and splits the power between left and right belt drives that engage either end of the tiller rotor (151). A bed former assembly (170) extends rearward from the tiller and includes a pan with a converging channel and a distal portion, positioned to receive tilled soil to form a raised bed. Shovel assemblies (190) are disposed on either side of the rotary tiller assembly. | ||||||

| A comminution machine included in an earth working machine which can be moved over a terrestrial area to be worked in a direction of working comprises a rotating roller comminution device. A grader blade is mounted on the comminution machine down stream from the comminution device in the direction of working. | ||||||
| 143 | Conservation implement including a shredder | US741078 | 1996-10-30 | US5743338A | 1998-04-28 | Pompeyo Jaime Benavides Gomez; Antares Salvador Ortega de la Cruz; Raul Americo Reyes Gonzales; Senen Alfonso Arzate Ramirez; Jesus Esteban Garza Huerta; Jose Rafael Garcia Villanueva |
| A conservation tillage implement including a shredder with a transverse rotor hood structure having one-piece end panels which are welded to each side of the hood and project rearwardly of the hood to receive a toolbar which extends the width of the implement. The center of the toolbar is connected to a pair of parallel upright central panels which are connected to the central rear portion of the hood. A reinforcing member extends from the central rear portion between the central panels around the top of the hood adjacent the hitch structure which connects the implement to a tractor. The end and central panels and reinforced hood structure define a compact, unobtrusive frame which is sturdy enough to pull heavy drawbar loads and resist heavy torque loading. In one embodiment of the invention, the toolbar supports a plurality of transversely adjustable deep tillage tools such as rippers, and disk structure is connected by adjustable bracket structure to the toolbar behind the rippers. Transversely adjustable lift and transport wheels may also connected to the toolbar, along with transversely adjustable down-limit members for limiting disk penetration and supporting the disk structure above the ground when the wheels are lowered to the transport position. A variety of earthworking tools, including those presenting a heavy draft load, can be mounted at different locations on the toolbar. | ||||||

| The equipment system consists essentially of the undercarriage 101 having supporting wheels, the rotary device with dovetailing prongs 102, the sowing machine 103 and the land roller or clod breaker apparatus 104. The system components may be used in various combinations or individually. | ||||||
| 145 | Combination implement for agricultural cultivation | US528463 | 1983-08-31 | US4509438A | 1985-04-09 | Willy Rau; Christian Taus |
| A combination implement for agricultural cultivation has a main frame liftably connectable with a pulling or dragging machine and supporting a cultivating device, and an auxiliary frame carrying a crumbler roller which supports the combination implement during cultivation and is adjustable relative to the main frame, wherein a supporting member is provided between the main frame and the auxiliary frame and has a play so that the main frame with the cultivating device arranged thereon can be upwardly deflected relative to the auxiliary frame or the crumbler roller during the cultivation. | ||||||
| 146 | Soil cultivating machines | US806671 | 1977-06-15 | US4181180A | 1980-01-01 | Cornelis van der Lely |
| A soil cultivating machine has a front row of subsoil penetrating tools and a second soil working member or row of members that work the top soil. The tools can be strip-shaped tines, at least some of which have plate-shaped elements pivoted to their lower ends. The elements or tines are connected to an eccentric mechanism that periodically raises and lowers the elements as the machine is operated. The second soil working member can be a row of tined rotors or an elongated further working member that extends transverse to the direction of travel and works the top soil from a direction that is different from the direction of movement of the strip-shaped tines. Intermixing the worked top soil and the subsoil is prevented. | ||||||
| 147 | Soil cultivating machines | US806663 | 1977-06-15 | US4149600A | 1979-04-17 | Cornelis van der Lely |
| A cultivating machine has subsoil tines and corresponding plate-shaped elements are pivoted to the lower portions of the tines. A driving mechanism, including at least one eccentric is connected to one or more of the elements or tines and the elements are caused to pivot up and down at their working depths to only partially raise the subsoil. The driving mechanism can also be connected to a further soil working member with soil engaging bars positioned to oscillate and work the topsoil. | ||||||
| 148 | Rotary tiller device adapted for chopping | US591098 | 1975-06-27 | US4044841A | 1977-08-30 | Alexander Smith; Burton D. Baggs, Jr. |
| A device in the nature of a rotary tiller equipped for traveling through fields as well as uneven terrain, for effectively chopping up encountered clods, vegetation and debris, and mixing same with the soil. We utilize a framework in which either of two different types of bladed, couner-rotating rotors may be effectively mounted, with one type of rotor having a number of outwardly extending teeth that are adapted for penetrating the ground as the tiller device moves thereover. The outermost portion of each tooth is provided with a novel cutting blade, which may interact with a stationary shear bar, with this type of blade being well adapted for chopping up encountered vegetation and for mixing it thoroughly with the soil. Another type of blade usable in our rotary tiller is a cylindrially-shaped gumbo rotor, utilizing a number of essentially flat, peripherally disposed blades, each of substantially rectangular configuration, which blades are oriented such that their principal surfaces each form a part of the exterior of the cylinder, and with each blade having a long edge that is sharpened, and caused to engage the soil. This latter type of rotor advantageously will not clog or become ineffective, even in very sticky soil. Our tiller device is equipped for mounting either type of rotor in such a manner that the depth of cut can be carefully controlled, and such that the closeness of the toothed blade to the shear bar can be carefully controlled. We preferably utilize a spring bias arrangement in the fore and aft positioning of the rotor, such that upon a hard obstacle becoming lodged between the shear bar and the rotor teeth, the spring bias can be overcome in such a way as to cause an enlargement of the distance between the teeth and the shear bar, such that the obstruction can pass through. Other features of our invention include the use of at least one skirt on the rear of the device for assuring a highly satisfactory leveling action. | ||||||
| 149 | Plow and earth fragmentation machine | US520196 | 1974-11-04 | US3998276A | 1976-12-21 | Douglas M. MacMillan |
| This invention relates to earth processing equipment and, more particularly, to a scarifier or plow apparatus capable of deep soil penetration which has an attached earth fragmentation assembly. The apparatus comprises a frame mounting on its forward end, a scarifier assembly which is adjustable from the frame to provide varying soil penetration. An earth fragmentation assembly is permanently affixed to the frame immediately behind the scarifier and comprises a scoop bucket with internal, shaft-mounted rotatable arms or cudgelers for fragmentizing earth passing interiorly of the fragmentation assembly and with a fixed bottom support for the soil within the scoop bucket. This apparatus is particularly useful for the single pass processing of compacted agricultural beds. | ||||||
