Abstract: A disc mower conditioner utilizing a modular disc cutterbar to sever standing crop material by impact action supports the cutterbar from the header of the mower conditioner by a pair of transversely spaced support arms mounted by spherical bushings to the header to allow flexing of the support arms as induced by the cutterbar. The mounting of the spherical bushings utilize conical washers engagable with conical sockets in spacers to limit vertical movement of the spacer relative to the header when the corresponding support arm flexes. The mower conditioner header further includes an optional viney crop guide that has a curved leading edge that directs viney crop downwardly into engagement with the adjacent disc cutter. The viney crop guide is also bent inwardly to contain and control the flow of crop material.

Abstract: In the field of mass flow measuring apparatuses, it is known to provide a sensor member for the establishment thereon of streamline flow of bulk material, in which the sensor member design is optimised in order to minimise the effects of changes in the coefficient of friction between the bulk material and the sensor member.The invention relates to improvements in the construction of the measuring apparatus, whereby two mechanical quantities (such as a pair of forces; or a pair of moments) may be measured to provide additional data on the flow process. In particular, it is possible to determine an exit velocity value v.sub.e that is indicative of the momentum of bulk material in the sensor member.

Abstract: A modular disc cutterbar utilizes self-contained cutter modules clamped between alternating spacer modules by fasteners engaged with the spacer modules. To resist bending moments in the cutterbar, selected fasteners can have a length to span more than one cutter module. The drive mechanism is also of a modular construction including a symmetrical, reversible sealed drive apparatus within each cutter module and a transfer shaft passing through each interstitial spacer module to interconnect each cutter module drive mechanism. The drive apparatus incorporates an oil slinger to keep the remote seals lubricated. The rock guard for each cutter module is mounted on the adjacent spacer modules, while the skid shoe mounting is simplified. A crop mover mounted on each disc member above the cutting knife improves the transfer of severed crop material.

Abstract: An agricultural baler having a main frame, a stuffer for loading successive charges of crop material into a baling chamber installed on the frame and a plunger for compressing the charges into packages of crop material. When the package has reached a predetermined length, a trip mechanism actuates a tying mechanism to tie a series of strands around the package to form a finished bale. The drive line to the tying mechanism comprises a dog clutch assembly including a continuously rotated hub and a dog lever positioned for possible engagement of a cam lobe on the inner surface of the hub. In between tying cycles a lever of the trip mechanism keeps the dog lever away from the hub surface. A timing cam cooperating with a roller on the lever precludes the actuation of the dog clutch when the cam lobe passes in the vicinity of the dog lever.
