| 101 | Agricultural planting machine having interchangeable seed meters | US10875729 | 2004-06-24 | US07152541B2 | 2006-12-26 | Timothy J. Ptacek |
| Each opener of a seed planting machine may be essentially tool-free equipped with a selected one of two or more types of interchangeable singulating meters. Each type of meter is mounted on its own adapter plate to present a module that has quick-attach mounting projections arranged and configured in an identical manner to all other modules. The projections fit into mating slots on an upright member of the opener, and the upper projection of each pair is in the nature of a downturned hook that facilitates hanging the module on the opener while also retaining it against fore-and-aft displacement. A stabilizing clip at the rear of the module securely receives the lower, rear edge of the adapter plate, and an over-center toggle latch securely retains the plate within the stabilizing clip to complete the solid yet readily removable attachment of the meter to the opener. A chain drive assembly for the meter is permanently installed on the opener so as to not be removed therefrom during interchanging of the meters. A support plate for the drive assembly is normally close to the meter in an operating position but can be swung outwardly to a release position when a latch between the support plate and the metering module is released, thus disengaging the drive assembly from the meter and providing clearance for the metering module to be lifted and removed from the opener. | ||||||
| 102 | Tractor hitch transmission | US10623467 | 2003-07-18 | US20040132567A1 | 2004-07-08 | Gert Schonnenbeck |
| The invention involves an agricultural machine with a drive train to be coupled onto the power take-off shaft of a tractor, with a transmission integrated into the drive train. In these types of agricultural machines it is frequently necessary, after starting at a high torque, to select a lower transmission ratio, so that the agricultural machine can be driven at an optimal speed by an engine to which sufficient power is then still available for the propulsion for the tractor. In order to make this possible, it is proposed, in an agricultural machine of this type, to construct the transmission as a continuously variable conical-disk belt or chain transmission which is preferably fully hydraulic, is coupled with a hydraulic clutch, and has idle-shifting in the starting transmission ratio. | ||||||
| 103 | Coupling for a flexible rotatable drive shaft | US10214964 | 2002-08-08 | US06729250B2 | 2004-05-04 | Michael Eric Friestad; Kevin Hause |
| A flexible rotatable drive shaft is provided with a first male coupling that is received in a second female coupling located on a gearbox. The male coupling has two circumferential grooves that define a first fully engaged position and a second intermediate engaged position. In both engaged positions the male coupler is mounted to the gearbox, however only in the fully engaged position is the flexible rotatable drive shaft in a driving relationship with the gearbox. The female coupler is provided with a latch pin for selectively engaging the first and second circumferential grooves. The latch pin is provided with a circumferential surface for engaging the grooves and latching the flexible rotatable drive shaft to the gearbox and a recessed section for unlatching the flexible rotatable drive shaft from the gearbox. | ||||||
| 104 | Restraint for a flexible drive shaft gearbox | US10214968 | 2002-08-08 | US06715433B1 | 2004-04-06 | Michael Eric Friestad |
| A flexible rotatable drive shaft is used to drive a seed meter of a seeding machine. The seeding machine is provided with a seed meter gearbox. The seed meter gearbox has a flexible rotatable drive shaft receiving portion and a gear receiving portion. The gearbox output is drivingly coupled to the seed meter for driving the seed meter. The flexible rotatable drive shaft receiving portion extends outwardly from the gear receiving portion for receiving the drive ferrule of the flexible rotatable drive shaft. The gearbox restrain extends outwardly from the seeding machine and engages the flexible rotatable drive shaft receiving portion. The gearbox restrain comprises two legs that are parallel to the gearbox drive axis. The flexible rotatable drive shaft receiving portion is sandwiched between the two legs to prevent rotation of the gearbox. | ||||||

| 106 | Twin row planter | US09940014 | 2001-08-27 | US06520100B1 | 2003-02-18 | Steven Maurice Spooner, Sr.; Paul Barrett Wood; Eric Thomas Jorgensen |
| A twin row planter (10) includes planting units (20a-26b) arranged in pairs (20-26). Each pair (20-26) is configured and positioned for planting two rows (78,80) of seeds less than about ten inches apart to produce two rows of crops in order to increase the yield of the plot. With this spacing, the rows (78,80) in each pair are close enough to simulate a single row enabling the use of a conventional cultivator, sprayer or harvesting machine. | ||||||
| 107 | Variable rate drive | US09870174 | 2001-05-30 | US20020178981A1 | 2002-12-05 | Paul E. Drummond; Colin D. Christy; Eric D. Lund |
| A drive apparatus has a first and second shaft rotatably mounted on the agricultural fertilizer implement. A drive wheel is fixed to the first shaft and an output wheel fixed to the second shaft. There are a plurality of wheels coupled to the first shaft and a plurality of wheels of varying sized fixed to the second shaft. A flexible connecting means is trained between a pair of selected wheels on the first and second shafts. A drive means rotates the drive wheel. A connecting means couples output wheel to the metering device. An engaging means is coupled to each of the plurality of wheels located on the first shaft coupling the selected wheel on the first shaft with the first shaft so that the wheel will rotate with the first shaft. There is also a control means that allows a user to selectively activate one of the engaging means located on the first shaft. When one of the engaging means is activated, one of the plurality of wheels is coupled to the first shaft and begins to rotate with the first shaft. The corresponding wheel located on the second shaft, coupled to the wheel on the first shaft by the flexible connecting means, begins to rotate the second shaft. The output wheel begins to rotate with the second shaft and transfers power to the metering device which regulates the amount of fertilizer dispersed from the implement. | ||||||
| 108 | Split meter roller for agricultural air carts | US09428524 | 1999-10-28 | US06240861B1 | 2001-06-05 | Russell J. Memory |
| A metering system for an air cart is provided in which a portion, preferably one-half, of a meter roller can be selectively disengaged from a common drive input. The metering system typically comprises two roller halves located in a common housing. The driven half of the meter roller is directly rotated by the rotation of the drive input. In a preferred embodiment of the invention, the controlled half of the meter roller is engaged or disengaged from rotation by a wrap spring clutch. The drive input does not engage the controlled meter roller half directly. Instead, the drive input extends within a hollow shaft which extends through the controlled half of the meter roller with the drive input lying concentrically within it. When only half the meter roller is required, the operator can disengage the clutch and stop rotation of the controlled half of the meter roller without stopping the operation of the air cart. In other words, the drive input provides continued rotation of the driven half of the roller with rotation of the controlled half being dependent on activation and deactivation of the clutch. This unique design enables the meter assembly to be contained in a common housing while providing a simple ways for controlling a portion, e.g. half, of the meter roller. The clutch may be remotely activated by the operator. Therefore, when the operator requires the entire meter roller to rotate, the clutch is engaged. When only half the meter roller is required, the operator can disengage the clutch and stop rotation of the controlled half of the meter roller without stopping overall operation of the air cart. | ||||||

| The invention is a mobile bin with two conveyors with each mounted on a main frame and with the main frame having wheels for rotatably supporting the vehicle along the ground. The bin has an opening along its bottom and the first belt conveyor is mounted beneath the opening in the bin and its remote ends extend to the opposite ends of the bin. A second elongated belt conveyor pivotally mounted about a vertical axis on the main frame of the bin vehicle from a storage position parallel in length to and beside and below the first belt conveyor to different positions laterally in length to the first belt conveyor with it one end remaining below and now beneath the one end of the first belt conveyor, said second belt conveyor being further pivotable about its one end on said mean frame to raise and lower the other end of the second belt conveyor while its one end remains below and beneath the one end of the first belt conveyor, whereby material may be conveyed from the bin opening by the first conveyor to its one end and then conveyed onto the second conveyor beneath the one end of the first conveyor whereupon it may be conveyed by the second conveyor laterally outward or laterally outward and upward from the one end of the first conveyor. | ||||||
| 110 | Broadcast spreading top dresser | US146449 | 1998-09-03 | US6149079A | 2000-11-21 | George Kinkead; Matthew A. Donner |
| A top dresser (10) includes a spinner assembly (40) removably connected by clips (44) to a cross beam (20) of the frame (12) mounting a hopper (30). The first and second sides (36) of the hopper (30) slope downwardly and inwardly to a conveyor (140) formed by sheeting (70) in the form of an endless belt having a relatively smooth outer surface. The valve (84) for the hydraulic motor (164) of the conveyor (140) is in series downstream of the valve (78) for the hydraulic motors (56) for the spinners (54) of the spinner assembly (40). Thus, it is not possible to mistakenly run the conveyor (140) without the spinners (54) operating. Therefore, the top dresser (10) is able to spread extremely minimal amounts of material evenly and without clumping or bunching. | ||||||
| 111 | Interlock system for spreader bodies | US412454 | 1999-10-04 | US6123276A | 2000-09-26 | Glenn Ungerer; Timothy Ray Schenk |
| Systems for reducing the possibility of inadvertent activation of an auger located in a supply body and/or spreader device while the covers of such a body or spreader device are open are provided. A motor that is drivingly connected to the auger is provided, as is a power supply for the motor that includes first and second engageable couplings. An arm located adjacent the spreader device is included, and is movable between a position that prevents opening of the cover and a position that permits opening of the cover. The first coupling is located with respect to the arm so that the first and second couplings may be engaged only when the arm is in a position that prevents the cover from opening. The cover can only be opened when the first and second couplings are separated, thereby interrupting the power supply to the motor and preventing operation of the auger. | ||||||
| 112 | Shaft rotation indicator clip | US205907 | 1998-12-04 | US5950550A | 1999-09-14 | Gary Deloy Luxon |
| A seeding implement adapted to be towed forwardly over the ground is provided with a seed meter coupled to a material hopper for receiving seed. The seed meter is driven by a drive shaft for dispensing seed to a furrow at a rate determined by a rate of rotation of the drive shaft. An indicia bearing member is releasably secured to the drive shaft for rotation therewith. The indicia bearing member includes two side legs secured to the drive shaft and a reflective portion connected to the side legs, said reflective portion extending along an axis of the drive shaft for indicating rotation of the drive shaft to an operator. | ||||||
| 113 | Clutch for chemical dispenser for planter | US471504 | 1990-01-29 | US5024173A | 1991-06-18 | Harry C. Deckler |
| A clutch arrangement for a particulate chemical meter for use in a planter includes an axially and rotationally moveable shaft having a coupler on a first end and a knob on a second end thereof. The clutch shaft is inserted through and coupled to a chain-driven sprocket and sprocket sleeve combination. A coiled spring disposed about the shaft urges the shaft toward and in engagement with a dispensing rotor of the chemical meter for dispensing an insecticide or herbicide. Rotation of the knob in a first direction causes a roll pin inserted through the shaft of the clutch to ride up a cam surface disposed on an end of the sprocket sleeve for axially displacing the clutch shaft and disconnecting it from the rotor. Further rotational displacement of the knob positions the shaft roll pin in a notch also disposed on the end of the sprocket sleeve for maintaining the clutch disengaged. Rotational displacement of the knob and clutch shaft in a second, opposed direction permits the roll pin to slide down the cam surface under the urging of the coiled spring for automatically engaging the clutch when the planter is moved and the sprocket is displaced in the second direction of rotation. | ||||||
| 114 | Planter population reduction drive unit | US766188 | 1985-08-16 | US4623078A | 1986-11-18 | Ralph E. Weeder |
| A planter population reduction drive system includes a third shaft adapted to be added onto a planter implement transmission unit having existing first and second shafts. The individual planter units are driven by the second shaft which is connected by a series of adjustable wheels to the first shaft for a selected population rate. The new third shaft is driven by the ground wheels and includes primary and secondary belt drive connections to the first shaft. A normally engaged wrap spring clutch on the third shaft normally provides for the transmission of torque from the third shaft to the first shaft but when the wrap spring clutch is disengaged, torque is transmitted through a secondary drive wheel which is mounted on the third shaft by an over running clutch. | ||||||

| 117 | Method and apparatus for minimum tillage farming | US32222473 | 1973-01-09 | US3811387A | 1974-05-21 | MEINERS E |
| Tillage required and fertilizer and herbicide consumption is minimized by placing fertilizer deep in the soil in the fall without thoroughly mixing the fertilizer and soil. The fertilizer is placed by first forming a deep channel, placing the fertilizer in the channel and forming a mound of dirt over the imbedded fertilizer. In the spring, seeds are planted in the top portion of the same mound. This method results in diminished weed growth and increased crop growth while using less amounts of fertilizer and herbicides. The same basic mound structure is then maintained from year to year. The tillage, fertilization and cultivation are performed with a single, combination farm implement comprising a platform having a number of plows, bedders and fertilizer applicators mounted thereon in the fall. In the spring, the same platform has spreaders, planters and bedders for planting mounted thereon.
