Abstract: In a mower having a frame and a plurality of rotatable disks supported by the frame, a driving device is operable to rotate each disk, and includes a driving wheel associated with each disk, and a shaft in driven connection with a corresponding driving wheel. A coupling in driven connection with a corresponding shaft for coupling a corresponding disk to the corresponding shaft is provided, and an antifriction bearing guides the corresponding shaft. Each driving wheel and its corresponding shaft, coupling and anti-friction bearing constitutes a separately replaceable subassembly in the mower.

Abstract: A supporting structure for an agricultural machine which may be connected to a movable vehicle includes a first frame adapted to be connected to the vehicle, a second frame adapted to be connected to the agricultural machine, an articulation device including a pivotable parallelogram mechanism connected to the frames, and permitting movement therebetween, and restraining devices limiting the movement between the frames.

Abstract: A rotary mower includes first and second supports extending in a predetermined direction and connected to one another end-to-end, and a set of elongated blade carriers rotatably mounted on each support. Each blade carrier, upon rotation, defines a trajectory, and neighboring blade carriers on opposite supports are mounted so that their trajectories do not overlap. First and second drive units are provided to drive each set of elongated blade carriers, respectively.

Abstract: A mower-conditioner for cutting and conditioning grass or other fodder comprises in combination a housing accommodating a cutting device (for example a bottom-driven disc-type rotary scythe device or a reciprocating cutter bar device) and a first conditioning device (for example a flail drum rotating about a horizontal axis and provided with pivotally-mounted flails), and a second conditioning device (for example a belt-driven fluted drum). The said first and second devices have at least one element (for example the said flail drum and driving belts or the like) in common. There are combs and grids to act on the cut fodder, and the mower-conditioner is readily adjustable for the treatment or production of different kinds of fodder.

Abstract: A power harrow has a frame that is normally substantially horizontal and at least one rotor. A rotatable shaft is journalled near one end in a bearing secured to the frame. The rotor is in driven connection with the other end of the shaft, and is rotated about a normally upright axis, so as to make contact with the soil to work it. A protective shield surrounds the bearing from below.

Abstract: A grass forage harvester has mowing and/or gathering mechanism whereby cut grass is brought to cutter mechanism comprising a rotor with peripheral cutter blades and to impelling mechanism comprising fan or projector vanes. The said cutter blades are articulated on the rotor and cooperate with at least one counter-blade which is placed between the said cutter mechanism and the said impelling mechanism to retain the grass so that it is cut into small pieces before it passes to the impelling mechanism. There is an elevator funnel through which the small pieces are raised for delivery into a vehicle.

Abstract: The disclosure is of a haymaking machine with two or more rake heads, a chassis, and a beam, and also means which automatically and simultaneously cause a pivoting of the chassis of the rotary rake heads about a substantially horizontal spindle of a pivot when the said chassis is pivoted about a substantially vertical spindle of the said pivot to modify its orientation in relation to the direction of travel of the machine when the latter is changed from the central tedding position into the lateral windrowing position and vice versa.

Abstract: The disclosure is of, in a mower which works over a great cutter width and comprises cutter discs or cutter drums or cutter belt pulleys or other rotary elements involved in the cutting operation, at least one device for reducing the width of the windrows comprising an endless flexible windrowing member which travels around two drums having substantially vertical axes of rotation, the first of said drums being approximately above one of said rotary elements at one extremity of the mower, the second of said drums being spaced to the rear of and nearer to the middle of the mower so that the windrowing member follows a path at an acute angle to the cutting front, at least one of said drums being driven at a speed different from that of said rotary elements so that the windrowing member impels cut fodder from a margin towards the middle of the windrow.

Abstract: The disclosure is of a fodder mower-conditioner mounted laterally of a tractor and comprising two or more rotary-scythe cutters and one or more conditioning rotors all rotating about axes which as viewed from above fall within a horizontal plane of a width equal to and containing the horizontal diameters of the tractor rear wheel tires, the rear wheel tire which is nearer the mower-conditioner being nearer to the nearest cutter trajectory than to the nearest conditioning rotor bearing.

Abstract: The disclosure is of a haymaking machine with a rotary rake head and a control mechanism for adjustable tool-carrier arms which are mounted for pivoting in support bearings which are wedged between two covers, one of which is situated above the control mechanism of the tool-carrier arms and is fast with the drive hub of the rotary rake head, and the other of which is situated below the said control mechanism of the tool-carrier arms.

Abstract: A haymaking machine for central tedding and lateral windrowing has a pair of rotary rake heads carrying working tools. The tools are rotatively interconnected by means of a support chassis that carries a forwardly extending frame beam. The direction of rotation of the rotary rake heads automatically reverses when the relative position between the support chassis of the rotary rake heads and the frame beam is modified, thereby to transpose the machine from the tedding position into the windrowing position and vice versa.
