| An agricultural implement (10) has front and rear gangs (12, 13) of rotatable tillage tools arranged to follow each other along a line of travel. The front and rear gangs (12, 13) are mounted to a main frame (21F), which is mechanically linked to a hitch frame (22) by a self-leveling linkage system (32, 33). The linkage system (32, 33) includes a spring assembly (48) arranged to allow relative movement between the hitch frame (22) and the main frame (21F) when the implement (10) is in a lowered field working position. The linkage system (32, 33) has a pivoting cam (41) for changing the field working preload of the spring assembly (48) to provide multiple hitch operation modes. The linkage system (32, 33) is arranged to make the main frame (21F) level and the hitch frame (22) rigid relative to the main frame (21F) when the implement (10) is in a raised position. The linkage system (32, 33) also includes an adjustable stop device (43) that limits upward hitch movement to provide multiple rear gang hitch operation modes. | ||||||

| An implement for soil preparation is moved in a direction of travel by a tractor with a three-point linkage. The implement includes an attaching mechanism, a coupling member with three coupling points, a first tool beam which is attached to the coupling member, at least one tool which is supported by the first tool beam, and three coupling elements which are each movably attached to the coupling member in the region of the respective coupling points to connect the coupling member to the attaching means. The first coupling element defines a path of movement for a guided movement of the first coupling point with respect to the attaching means. The second and the third coupling element each define a path of movement for a guided movement of their respective coupling point with respect to the attaching mechanism. | ||||||

| A crop harvesting machine includes a crop harvesting header mounted on a transport vehicle for carrying the header across the ground with at least one upper connecting link extending from the vehicle frame to an upper frame member and two support arms each extending from a front end at the header to a rear end pivotally mounted on the vehicle frame and arranged at a height below the upper link. Each support arm has a respective float spring connected thereto at a pivot thereon forwardly of the rear end and extending therefrom to the vehicle frame for applying a lifting force on the support arm. Each support arm has a pivot connection at the rear end defined by a pivotal link connected at a forward end to the frame by a resilient bushing and at a rear end by a similar bushing to the rear end of the support arm. The pivotal link is inclined upwardly and rearwardly in the normal operating position and thus pivots downwardly and rearwardly on an impact so as to absorb the impact on the crop cutter and tending to cause pivotal movement of the support arm relative to the pivot connection to the float spring to effect lifting movement of the cutter relative to the ground. | ||||||

| A coupling device for mounting an agricultural implement on a tractor equipped with a belt drive, which includes two coupling halves which are connected to each other by several coupling rods, designed in such a way that no components working on the linear drive principle are needed. According to the invention, the lower right and left coupling rods include in each case a lower front and a lower rear rod section which are connected to each other, and which are freely movable relative to each other. One end of the lower rear rod section carries an expanded portion, which is located inside a housing of the end region of the lower front rod section. A plurality of elastically deformable equalizing bodies are inserted between the inner surfaces of the housing of the end region and the outer surfaces of the expanded portion, limiting the movement of the lower rear rod section in relation to the lower front rod section. | ||||||
| 13 | Resilient hitch linkage for connection between a towing vehicle and a towed apparatus | US856771 | 1977-12-02 | US4147376A | 1979-04-03 | John J. Slazas |
| A resilient hitch linkage between a towing vehicle such as a tractor and an implement or attachment such as, for example, a rotary tiller, towed by the towing vehicle. The resilient hitch linkage serves to reduce the transmission of impact or shock loads and/or vibrations between the implement and the tractor and includes a front link pivotally connected to a hitch point on the tractor and a rear link pivotally connected to the attachment being towed. One of the pivoted links, such as the rear link, has a member with multiple flat exterior surfaces such as a member of rectangular cross section (a "square tube") secured thereto and extending laterally therefrom. The other pivoted link, such as the front link, has a first U-shaped clamp member secured thereto and lying on one side of the "square tube" carried by the one link. A pair of rubber cylinders are retained by the first clamp member. A second U-shaped clamp member is positioned on the opposite side of the "square tube" from the first clamp member, the second clamp member retaining a second pair of rubber cylinders therein. The two clamp members are fastened together to confine the plurality of rubber cylinders under pressure between the "square tube" and the clamp members, thereby defining a resilient connection between the front and rear link members. The rubber cylinders are deformed under the pressure exerted upon them. In the preferred embodiment, the resilient connection between the front and rear links is offset from the straight line connecting the respective pivotal connections of the front and rear links to the tractor and to the implement towed by the tractor, at least under normal operating conditions (i.e., in the absence of shock or impact loads). An upper and a lower resilient hitch linkage, each embodying a construction of the foregoing type is connected between the towing vehicle such as a tractor and the implement or attachment being towed by the tractor. | ||||||
