Abstract: A mower with two pairs of counterrotating cutting disks has a frame on which two yokes are mounted for independent swinging about a horizontal axis transverse to the direction of travel, each yoke carrying a pair of coacting horizontal conditioning rollers which in a working position lie in the wake of a respective disk pair to gather and press the mown crop coming from these disks. The conditioning rollers are driven from a pair of ancillary shafts on the machine frame, operatively linked with the disk drive, through extensible and universally jointed transmission shafts enabling each yoke to be separately swung into a retracted position.

Abstract: A drive system for a field chopper in which a belt and friction wheel transmission operates the blade drum or cutter reel and is driven from a speed-reducing and distribution drive having a number of output shafts which operate the pickup and intake elements of the harvester.

Abstract: A spring tine assembly for agricultural machines has prongs extending from a coil spring in a direction substantially perpendicular to the coil axis. An elastic retainer bridging the prongs or crop-engaging tines forms a passage for each of the prongs and is depressed thereagainst by clamping means, e.g. bolts. The assembly is useful for agricultural machines and, more particularly, for haymaking machines.

Abstract: A field chopper, having a chopper drum or reel rotatable on the chassis and a plurality of feed rollers for advancing the crop material to the chopper drum, is provided with a pair of arms flanking the drum and swingable about the axis thereof. The arms each carry a pivotal compensating bar, a pair of pressing rollers being journaled on these arms and being driven by gears meshing with a central pinion whose shaft forms the axis of one of the bars and is, in turn, driven by a transmission. The pressing roller proximal to the blade drum is received in notches in the compensating bars and is connected thereto so as to be easily releasable.

Abstract: A harvesting machine having a plurality of vertically reciprocal shaking elements is provided at the top of each of these elements with a distributing plate that extends the full length of the shaking elements and is pivotal about an axis on this shaking element. Each of these distributing plates is oscillated about its respective axis so as to loosen up and order the straw lying on the shaking elements and at the same time to separate grain from them. The plates have sawtoothed upper edges and may be oscillated at a rate equal to three times the vertical reciprocation rate of the shaking elements.
