| 81 | FRAME CONFIGURATION FOR AN AGRICULTURAL TILLAGE IMPLEMENT | US14520698 | 2014-10-22 | US20150129261A1 | 2015-05-14 | Matthew R. Sudbrink; Dean A. Knobloch |
| An agricultural tillage implement includes a center frame section having a front frame member extending transverse to a travel direction, a rear frame member extending transverse to the travel direction, and a plurality of longitudinal frame members extending from and attached between the front frame member and the rear frame member. The plurality of longitudinal frame members include a pair of side frame members positioned at respective sides of the center frame section, and a pair of load distribution frame members. A plurality of tillage implements extend downwardly from the center frame section. A pull hitch is directly attached to the front frame member at two attachment locations and extends forward from the center frame section in the travel direction. Each attachment location is aligned with a respective load distribution frame member. | ||||||

| 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. | ||||||
| 83 | Suspended drawbar control with selectable operating modes | US11528221 | 2006-09-26 | US20080121401A1 | 2008-05-29 | John H. Posselius; Christopher A. Foster; Kevin M. Smith |
| A control for a drawbar of a hitch for a work machine, and at least one method of operation thereof, which provides operator selectable operating modes having different characteristics for different operating conditions and operator preferences, some of which modes being automatically adaptable for changing conditions, such as loading conditions and the like. Selectable operating modes can include, but are not limited to, a locked out mode; a stiffness mode; a position limited mode; a varying load mode; and an active mode. | ||||||
| 84 | Suspension system for a three-point apparatus | US11338562 | 2006-01-24 | US20060118312A1 | 2006-06-08 | Dan Steinberger; Alan Redman; Lawrence Bernard; Leslie Willemssen |
| A three-point apparatus is disclosed comprising a hitch system, an implement, and a suspension system. The hitch system is comprised of a base and a three-point interface. The base of hitch system is coupled to the three-point interface of the hitch system. The three-point interface is configured to connect to a three-point system, such as the three-point arms of a tractor. The suspension system is coupled between the base of the hitch system and the implement. | ||||||
| 85 | Coupling device | US09923514 | 2001-08-07 | US06601654B2 | 2003-08-05 | Hubertus Küsters; Joachim Oldenburg |
| 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. 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. | ||||||
| 86 | Telescoping carrier for forestry equipment | US13616 | 1979-02-21 | US4393943A | 1983-07-19 | Albert Andersson |
| A forestry cultivation instrument, particularly a scarifier, is attached to a telescoping carrier. In operation, the carrier is connected to a vehicle and, when an obstacle is encountered, the carrier may telescope outwardly thereby reducing shock loading to both the vehicle and the scarifier. The telescoping members are held contracted by fluid pressure with the telescoping occurring, after the obstacle is encountered, when the obstacle causes fluid pressure to increase beyond the pressure which would occur from normal drawing resistance of the scarifier. The fluid pressure may then be used to aid the operator in clearing the scarifier from the obstacle. Various other forms of forestry equipment may be substituted for the scarifier. | ||||||
| 87 | Coupling member | US905966 | 1978-05-15 | US4236613A | 1980-12-02 | Cornelis van der Lely |
| An elongated coupling member is connectable to the upper link of a three point tractor lift and to an implement carried by the lift, such as a spreader. The member includes a piston slideably mounted in a cylinder and a hydraulic circuit between a space at each side of the piston. The piston can be adjusted to a set position in which the relative positions of the piston and cylinder are maintained by hydraulic fluid within the circuit and spaces. An overload device, such as a spring biased, one-way valve, is included in the circuit so that upon overload, the piston moves, usually to lengthen the coupling member and allow fluid to flow from one space to the other. In one version, an overflow space or reservoir is in the circuit to accomodate excess fluid when the piston is shifted and one space is larger than the other. A pressure gauge in the hydraulic circuit indicates the fluid pressure in the circuit and since the pressure decreases incrementally as material is being spread from the implement, a measure of the amount of material dispensed can be gained. | ||||||
