| PURPOSE: To prevent an overload of planetary reduction gear, by resiliently contacting a ball to the peripheral hollowed part of a ring gear in the planetary reduction gear. CONSTITUTION: An input shaft 10, integrally formed with a sun gear 10', and an output shaft 16, integrally formed with a carrier 15, are concentrically arranged in a face-to-face position. Planetary reduction gears are constituted by meshing planet gears 9, supported to the carrier 15, to the sun gear 10' and ring gear 11. A ball 13 is forcibly contacted by resilient force of a spring 14 to a hollowed part 12, provided in the periphery of the ring gear 11, if an overload is caused, the ring gear 11 is rotated against the resilient force of the spring 14.

| 4 | BIASED DIAGONAL IMPLEMENT BRACE | EP07719372.0 | 2007-02-06 | EP1983816A1 | 2008-10-29 | BEAUJOT, Norbert |
| A diagonal brace apparatus for an implement frame includes a bias element connected to a front location on a front portion of the implement frame and connected to a rear location on a rear portion of the implement frame laterally offset from the front location. The bias element is operative to exert a bias force resisting rearward movement of an outer end of the implement frame with respect to an inner end of the implement frame. Conveniently the bias element is provided by a hydraulic cylinder which exerts a bias force and can extend to allow the frame to flex to reduce shock loading on the implement when excessive forces are exerted on the frame. | ||||||

| An arrangement for an implement (1) intended for soil cultivation which is so arranged as to be connected to a towing vehicle or similar via a hitch (13), said implement (1) being capable of pivoting about an articulation (14). The invention permits, amongst other things, automatic movement parallel to the ground by the implement (1) in question to be achieved by simple means. The hitch (13) and the implement (1) are connected to the aforementioned articulation (14), which is situated on a level higher than the level at which soil cultivating devices (3) forming part of the implement are so arranged as to be effective when they are introduced down into the ground (5), for which purpose the implement is so arranged as to be attached with the aforementioned hitch (13) behind the articulation (14), when viewed in the direction of working (15) of the implement, in such a way that a turning moment which is produced about the aforementioned articulation (14) is so arranged as to counteract the moment which arises as a result of the interaction of the implement with the ground (5). | ||||||

A second sensor unit is arranged on the elongate shaft and is configured to measure forces acting on the shaft. A processor is communicatively coupled to each of the first and second sensor units. The processor is configured to generate an output signal indicative of a soil characteristic based on the forces measured. | ||||||

| A harrow implement comprises a tool bar and harrow sections extending rearward therefrom. Each of a plurality of hydraulic cylinders is connected between the tool bar and a corresponding harrow section. A hydraulic control is operative to supply pressurized hydraulic fluid such that the hydraulic cylinders exert a substantially constant selected bias force on the harrow sections. The hydraulic control is operative to direct pressurized hydraulic fluid into a first port on each hydraulic cylinder to exert a downward bias force on the plurality of harrow sections, and operative to direct pressurized hydraulic fluid into a second port on each hydraulic cylinder to exert an upward bias force on the plurality of harrow sections. The hydraulic cylinder can be configured to raise the harrow sections to an idle position above the ground, and to a transport position extending up from the tool bar. | ||||||

| 12 | Agricultural implement having diverse hitch and gang operation modes | US15160474 | 2016-05-20 | US09497897B2 | 2016-11-22 | Mark Hennes |
| 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. | ||||||

| A agricultural implement incorporates a frame which is adapted to engage a three point hitch of a tractor. The frame employs a longitudinally extending member which is pivotally connected to a link member. A resilient yielding assembly is disposed between the longitudinally extending member and the link member to absorb forces exerted from the link member onto the longitudinally extended member. Accordingly, when the link is acted upon by forces which cause the link to exert a stress on the three point hitch of a tractor, the resilient yielding assembly allows the first link to pivot about the longitudinal member thereby reducing compressive loads exerted on the upper link of the tractor's three point hitch. | ||||||

| An agricultural implement, such as a baler, has a fly-wheel connection that disconnects drive to the ram and other baler parts upon overload. The fly-wheel includes a first member on a driving shaft that is connected to a second member on a driven shaft through at least one shear pin. Preferably, there are a plurality of pins that can be advanced upon overload and reduction in driving speed, to automatically re-establish connection between the two members. | ||||||
