The downwardly inclined position is used in order to enhance performance of the agricultural implement, especially dual wing implements. | ||||||
| 242 | System for the fast road transportation of cumbersome industrial or agricultural equipment | US233954 | 1994-04-28 | US5474136A | 1995-12-12 | Ivano Ficarelli |
| A system for the fast road transportation of a cumbersome equipment comprises a first plate coupled with a lifting unit and connected by a hydraulic jack to the equipment. Against this plate a second plate is coupled which is provided with two parallel, horizontal and elongated curved slots cooperating with four fixed pins, three of them being placed at the apices of a horizontal base triangle, the fourth being located in the middle of the horizontal base of the triangle. The slots extend as anti-clockwise curved slots, the upper one directed downward, the lower one directed upward and having radiuses equal to the distance of the fourth pin respectively from the apex pin and from the base pin. A further anti-clockwise curved slot is provided directed downward which starts from the lower slot at a distance from its end equal to the double of the distance from the fourth pin to the base pin. | ||||||

| A vehicle, such as a tractor, has an attachment implement, such as a plow. An automatic controller acts upon a power lift of the plow, which moves the plow during operation in trenching position. In a first control, this motion of the plow ensues relative to the tractor, so that the vertical absolute velocity component of the plow becomes approximately zero. The plow is so moved relative to the vehicle that it moves upward during a downward motion of the plow-tractor joint and downward during an upward motion of such joint. The tractor is this completely disconnected dynamically from the plow, so that the pitching vibration behavior of the tractor is not subjected to a negative change due to the moments resulting from the forces of acceleration of the plow and affecting the plow, as is the case with a vehicle having a rigidly connected attachment implement. In a second control, the plow is moved in opposite phase to the tractor to counteract a change of its pitching angle coordinate. This results in a pitching angle behavior having an amplitude which is less than that of a tractor without an attachment implement. | ||||||
| 244 | Locking hitch assembly | US681259 | 1984-12-13 | US4650206A | 1987-03-17 | Leon H. Mathis |
| The present invention relates to a simplified tractor hitch structure for use with implements and an improved plow attachment for use in developing firelines in forest soil. The hitch allows implements to be moved between a raised transport position and a lowered working position. In the former, however, a simplified approach is employed to provide locking and unlocking functions controlled by the tractor operator while seated in the tractor and to positively prohibit horizontal swaying of the hitch and thus the implement. | ||||||

| A multiple implement to tractor hitch assembly. A horizontally disposed elongated first beam is horizontally curved and connected intermediate its ends by a tongue with a tractor drawbar for horizontal pivoting movement of the first beam about the vertical axis of its tongue connection for positioning implements when connected with respective parallel end portions of the beam in a tandem or laterally spaced soil working position by a power cylinder extending between the first beam and the tongue. A second substantially identical beam is hingedly connected in tandem by one of its ends to the trailing end of the first beam for vertical pivoting movement of the beams about the horizontal hinge connection. An agricultural implement is connected with the beams at their hinged connection and with the respective other end of the respective beam. | ||||||
| 246 | Implement and transport wheel assembly therefor | US573748 | 1984-01-25 | US4585076A | 1986-04-29 | Robert J. Stevens; Clinton E. Bromley |
| An apparatus for transporting an earth working implement, most specifically, a roller-chopper unit for use in forestry, wherein a transporting wheel assembly is disposed upon the earth working implement or its frame thereby providing transportation for the earth working implement from job site to job site. The wheel assembly has a stored position in which the wheels are maintained while the earth implement is performing its task at a specific job site and the transporting wheel assembly further being movable between a working position in which the wheels are maintained against the ground and support the earth working implement during transportation between job sites. | ||||||
| 247 | Automatic lock for farm equipment transport wheel | US548963 | 1983-11-07 | US4534416A | 1985-08-13 | Terry L. Johnson |
| Movement of a wing frame to folded position moves a locking member into position to be engaged by the arm which actuates the wheels to lowered position. When engaged, the lock prevents the wheels from being raised. To disengage the lock the wing must be unfolded first to enable the locking lever to rise out of the way when the arm is actuated to disengage the lock. The entire operation is controlled hydraulically and the farmer need not get off his tractor to lock or unlock the rig. | ||||||
| 248 | Transport lock actuator | US364951 | 1982-04-02 | US4418516A | 1983-12-06 | James T. Donovan; E. Graham Webster |
| A transport lock actuating mechanism for a crop harvesting machine having a pivotally moveable tongue mounted to the frame of the harvesting machine, commonly referred to as a pivot-tongue windrower, is disclosed wherein a single spring is compressed to exert a biasing force on a locking pin to urge the pin through suitable aligned apertures in the base of the tongue and in the frame of the machine to automatically extend the locking pin through the apertures when they become aligned due to manipulation of the pivotal movement of the tongue by the operator at a location remote from the locking pin. The transport lock actuating mechanism is alternatively operable to exert a biasing force on the locking pin to urge the locking pin into a position withdrawn from the apertures so that the machine can be moved from a transport position to an operating position. | ||||||
| 249 | Multi-hitch apparatus for tandem towing of farm implements | US227983 | 1981-01-23 | US4381118A | 1983-04-26 | Harry D. Weeks |
| Apparatus for connecting a plurality of towed portable farm implement in optional dual configurations characterized by a first position wherein the farm implements are towed in a staggered or offset relationship to one another for field use and a second position wherein the farm implements are towed in aligned relationship behind the towing vehicle for over the road transportation. The apparatus includes a first tongue portion adapted to be pivotally mounted on the first farm implement between said first and second positions and locking means for releasably fixing the tongue in each of said positions. Additionally, a second hitch means is provided on a pivoted tow bar which is pivotally mounted to a swinging frame portion mounted on said first farm implement between an offset position and an aligned position. Releasably latching members are provided to fix said frame and said arm in the desired position. The arrangement of said first tongue portion and said swinging frame and pivoted tow bar carrying the hitching members cooperate with one another to assure that the hitched connection of said first tongue means is aligned equi-distant between the outermost opposing wheels of the farm implements being towed in either of the towed configurations to equalize the pulling force applied to the trailing towed vehicle. | ||||||
| 250 | Soil working implement including hydraulic centering and locking means for caster wheel | US247581 | 1981-03-26 | US4359105A | 1982-11-16 | Terry L. Van Natta |
| Hydraulic center and lock structure for the caster wheel of, for example, a tractor-drawn plow, operative on a centering element rigid with the standard of the caster wheel for forcibly centering the standard and ultimately locking the standard against turning about its axis when the caster wheel is in its straight-ahead position. The hydraulic device is bi-directionally operative for disengagement from the centering element to enable free castering of the wheel, as when the plow is raised for transport. The invention also provides two forms hydraulic control for coordinating the raising and lowering of the plow with unlocking and locking the caster wheel. In one form, the system provides for trapping fluid in the caster wheel cylinder in its straight-ahead position, with a separate valve operated manually to release the fluid when the plow is lowered to operating condition. In another form the valve that releases the trapped fluid is made responsive to a predetermined pressure. Both systems prevent unlocking of the caster wheel during relative minor height adjustments of the plow during operation. | ||||||

| A soil cultivating machine has a row of driven rotatable soil working members and a tool bar at the rear thereof to which tools, such as seed drills can be attached. The machine is connectable to a tractor lift and the members are driven via a p.t.o. At least one supporting member is detachably connected to the machine frame and the tool bar for operational support and transport purposes. The supporting member is elongated and extends rearwardly from the frame above the tool bar and to a rear support wheel. The supporting member includes a forward support that is pivoted to a rear arm and a hydraulic assembly bridges the pivot connection. Actuation of the assembly lifts the machine, including any tools on the tool bar so that the entire machine with attachments are supported solely by the tractor lift and the rear wheel or wheels. | ||||||
| 252 | Vehicle for handling multi-furrow plough | US569775 | 1975-04-21 | US3963137A | 1976-06-15 | William J. Chayer |
| 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. A variation of the above invention shows the hooks being attached to a pair of hydraulic jacks, thereby replacing the said ratchet operated cylinder and the swivel attachment of said central arm. | ||||||
