| 81 | Implement caster wheel | US463673 | 1995-06-05 | US5562167A | 1996-10-08 | Gregory J. Honey |
| A mounting assembly of a gauge wheel for an implement, such as an agricultural crop harvesting header, the mounting assembly including a king pin member rotatably mounted in a king pin bushing housing and having a wheel spindle projecting substantially horizontally from one side of a king pin shaft for rotatably mounting the gauge wheel. The rotational axis of the king pin shaft is tilted rearwardly and upwardly relative to the vertical and sideways and upwardly relative to the vertical in a direction opposite to the side of the projecting wheel spindle. Accordingly, when the gauge wheel enters a caster turn in a direction corresponding to the direction of projection of the wheel spindle the axis of the wheel spindle swings from a substantially transverse direction in relation to the straight ahead travel direction towards a rearwardly and downwardly inclined orientation. A spring is arranged to bias the king pin shaft to turn in a direction counter to a caster turn, and stops are provided to limit the rotation of the king pin shaft between a substantially straight ahead travel condition and a caster turn of a preselected amount of turn. Effective castering of a gauge wheel at the inside of a turn is accomplished together with good straight ahead stability. The structure also allows positioning of the castering gauge wheel close to the framework of the header. | ||||||

| 83 | Combined depth-control and wing-lift hydraulic circuit | US824415 | 1986-01-31 | US4700784A | 1987-10-20 | Kenneth J. Wiebe; J. Richard Harwood; Russell J. Martin |
| A combined depth-control and wing-lift hydraulic circuit is disclosed. The circuit is preferably used in combination with a farm implement having a tool bar. The tool bar is horizontally disposed relative to the ground, and is carried by the implement. The hydraulic circuit comprises means to raise and lower the tool bar relative to the ground, thereby to effect depth control. The tool bar includes pivotally connected wings. Each wing carries an associated wing wheel. The hydraulic circuit includes means for causing rotative movement of each wing about its associated tool bar pivot between a substantially horizontally-disposed position and a substantially vertically-disposed position, relative to the ground, and for further causing each wing to be selectively disposed at one of these positions, thereby to effect wing lift. Each wing wheel is coupled to, and is distally spaced from and located beneath, its associated wing structure when such wing is in the substantially horizontally-disposed position. Also, each wing wheel is outwardly spaced from its associated wing structure when the wing is in the substantially vertically-disposed position. The hydraulic circuit further includes means for causing each wing wheel to be drawn inwardly toward its associated wing structure when such wing is in the substantially vertically-disposed position, thereby to effect a special "wheel-tuck" feature of the present invention. The hydraulic circuit can additionally be used to control operation of a marker arm for forming marker furrows. | ||||||

| 85 | Wheel with stub axle releasably to end of powered tubular shaft | US527969 | 1983-08-31 | US4483400A | 1984-11-20 | Walter E. Arndt |
| A removable transport wheel assembly for a ground penetrating machine such as a roto tiller for providing removable wheels for movement of the machine from place to place and loading and unloading. The machine has a transverse power driven shaft carrying earth working implements and having tubular transverse ends. Pin assemblies have shanks that pass diametrically through the transverse ends of the shaft. A pair of wheels are provided each having a stub axle with a diameter to be slip fitted in a transverse end of the shaft, and with an enlarged shoulder to engage the transverse end of the shaft to limit axle movement of the axle into the shaft. Each stub axle has a slot which engages the shank of the pin assembly. At the inner end of the slot is a groove which provides a seat for the shank of the pin assembly to releasably fasten the wheels to the shaft of the machine for transport from place to place. The wheels are readily removed for using the machine in an earth working function. | ||||||
| 86 | Mechanism for spring loading a transport lock | US374356 | 1982-05-03 | US4418518A | 1983-12-06 | Earl E. Koch; A. Dale Gamber; Philip J. Ehrhart |
| A mechanism for spring loading a transport lock on a crop harvesting machine having a pivotally movable tongue mounted to the frame of the harvesting machine, commonly referred to as a pivot-tongue windrower, is disclosed wherein first and second springs are compressible 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. An actuating lever includes a camming surface that is selectively cooperable with either the bight portion of the housing or the base plate on the tongue to effect a compression of the first and second springs, respectively, to bias the locking pin toward either a locked or unlocked position. The lever maintains the respective spring in compression until the locking pin moves into the position in which it is being urged. | ||||||
| 87 | Dual implement hitch | US154206 | 1980-05-29 | US4344639A | 1982-08-17 | Lorne R. Pollard |
| A dual implement hitch for connection between a tractor and the implements for moving the implements to preferably an echelon position for field operation and to a tandem position for transport, while maintaining the tractor hitch pin on the line of pull of the implements. The hitch includes a hitch tongue pivotally connected to the tractor and to a support attached to the first implement. A curved beam is pivotally connected to the support forward of the tongue connection thereto and extends rearwardly over the first implement in the transport position to a caster wheel support and a pivotal connection to the second implement. Link means are pivotally connected to the hitch tongue and curved beam rearward of the pivotal connection of the curved beam to the support. A single hydraulic cylinder connected to the support and tongue provides the power for the movement of both implements to the noted positions from the tractor seat. | ||||||

| A locking device for holding an implement which is hung from a ground traversing frame in elevated transport position. The device comprises a free swing link pivoted on the frame and which is moving in a lifting direction is abuttable with a lever of the lifting linkage connected between the frame and the implement. The lever has a slot elongated in the direction of its movement and the slot is transversely alignable with a slot on an anchor lug fixed to the frame. These slots receive a pin therethrough for locking the lever to the anchor and accommodate the free link to swing away from the lever to permit separation of a hydraulic ram connected between the link and the frame. The extent and position of the slots permit storing the pin in either slot when the linkage is operational without the pin interfering with the operation of the linkage or causing the parts to break during operation of the ram if the pin is left in locking position.
