摘要： A connection apparatus for connecting a knife to a rotary disc cutterhead comprising a mounting stud having a specifically configured head disposed on the rotating cutterhead and a key hole opening on one end of the knife which permits the knife to moved into engagement with the stud and head when the knife is specifically oriented and then retained in place by the stud and head when the knife is moved into a normal operating position. A hand-operated biasing element prevents inadvertent disengagement of the knife from the stud. The key-hole opening and connection stud may also be configured to limit the angular orientation of the knife which will permit disengagement of the knife from the connection apparatus.

摘要： A crop guide comprising one or more generally wedge-shaped guides configured to interact with a crop discharge stream as it is discharged from an agricultural mower having a counter-rotating disc cutterbar. The guides are positioned rearward from the cutterbar, with one guide being generally positioned on an axis centered between each pair of converging-rotation disc cutterheads where crop material flow is concentrated. Each guide is generally pyramidal in shape, having a pair of surfaces angled with respect to one another and forming a triangular pyramid form with respect to a third generally planar surface, typically the mower swathboard. The vertex of the pyramid is oriented upstream in the crop flow so that a portion of the crop flow is split by the angled surfaces and laterally dispersed. This dispersion of crop material produces a crop mat on the ground behind the mower having a more uniform thickness compared to that produced by a traditional mower using a counter-rotating rotary cutterbar.

摘要： A split spacer ring that is connectable to a cutterbar PTO drive shaft and works in conjunction with an anti-wrap shield to reduce the effects of crop debris accumulating on the drive shaft. Radial removal of the split spacer ring allows the anti-wrap shield to be axially displaced to enable sufficient telescoping movement of the drive shaft to disengage an end from a rotary cutterhead connection and thereby remove the drive shaft or other cutterbar components for repair or replacement. Improved axial clearance provided by the removed spacer ring also facilitates installation and removal of a crop conveying drum that may be installed on the drive shaft.

摘要： A seal device for preventing entry of debris into a rotary cutter drive housing when a shock protection device having frangible drive features is removed after having fractured the drive features following a driveline overload condition. The housing includes an upwardly facing opening through which a drive shaft for the cutter extends. The drive shaft rotationally engages the shock protection device for driving the rotary cutter. The seal device is disposed in the upwardly facing opening beneath the protection device and includes drive means for rotation in unison with the drive shaft. The seal device further includes a seal interface for sealing interface with a contact seal disposed on the inner circumference of the opening thereby preventing the entry of debris into the housing.

摘要： An adapter for connecting a agricultural implement swivel hitch to a drawing hitch on a towing vehicle that enables relative pitch and roll movement between the implement and vehicle at a single, pinned joint. Elongated openings in a first portion of the hitch adapter receive a transversely aligned connection pin. The openings are sized to allow limited pin angular movement about a vehicular roll axis. A second portion of the hitch adapter is also connected to the connection pin and configured to allow limited relative angular movement about a transverse pitch axis. The connection between the first and second portions at the connector pin allows relative angular movement therebetween about generally co-planar pitch and roll axes. The connector pin is formed from a softer material than the surrounding first and second portions thereby providing an inexpensive and easily replaceable weak link in the hitch adapter assembly.

摘要： A shock protection device having opposing pluralities of frangible splines separated by an annular groove disposed in an internal splined opening in a drive hub, the splines for intermeshing engagement with a splined end of a drive shaft for transferring rotary motion to a cutter head from a driveline. Variation in the width of the annular groove enables precise adjustment of the fracture torque for the shock protection device beyond the adjustment possible through variation in the number or configuration of the individual splines.
