Abstract: An agricultural implement having an elongated main chassis member, ground engaging wheels for supporting the main chassis member on the ground and at least one set of two arms, each arm being provided with at least one working implement and each arm being pivotably connected to the main chassis member and adapted to be moved between a working position, a headland position and a transport position. In the headland position, an inner working implement of the at least one set of arms is displaced laterally away from the main chassis member.

Abstract: A remote controlled floatation chamber with a trolling unit can be directed to a selected site in order to treat and control aquatic plants. The chamber method allows use of a broad range of treatment agents including herbicide, chemical and microbe's and UV-C light waves to destroy aquatic species. Provisions for deflating floatation tubes on the chamber allow it to be remotely lowered over species to be treated. Once the chamber is placed over the aquatic specie the treatment agent can be dispersed within the small volume of the containment volume with minimum exposure to the surrounding water. A variable volume device or storage bladder within the containment volume may be used to recycle the herbicide once treatment is completed. The chamber can then be moved to another site and the cycle repeated.

Abstract: A pick-up assembly having a pick-up drum, rotatably mounted to a frame; a windguard, attached to a support linkage which is pivotably mounted to the frame; at least one winch drum, rotatably attached with respect to the frame; and at least one flexible elongate element having opposite first and second end regions. The first end region is attached to the support linkage and the second end region is windably attached to the at least one winch drum.

Abstract: A pick-up device, usable by an agricultural machine, includes a frame and first and second units. The first and second units each include a displacement device, are arranged beside each other and a small distance apart, are connected directly to the frame by respective first and second articulations having first and second distinct axes directed in a direction of advance, include respective first and second pick-up rotors rotatable about third and fourth axes, and are connected to one another by a guidance device. The first and third axes are in a same seventh plane, the second and fourth axes are in a same eighth plane. A stop mechanism defines two work end positions of the first and second units with respect to the frame, between which they can pivot freely within a limited range, and remain connected to one another regardless of their position between the work end positions.

Abstract: A pick-up device, usable by an agricultural machine, includes a rotating part including at least one support arm, to which are attached raking and picking up tools and which is configured to pivot about a rotation axis with respect to the rotating part by at least first and second bearings, the at least first and second bearings each including an outer ring rigidly fastened to the rotating part, and with respect to which outer ring the support arm can pivot about the rotation axis. The first bearing includes an inner ring configured to pivot about the rotation axis with respect to the outer ring and rigidly fastened to the support arm. A stop mechanism connects the inner ring to the outer ring, and limits displacement of the support arm with respect to the rotating part in a direction substantially parallel to the rotation axis to a small or nil value.

Abstract: A pick-up assembly for an agricultural machine having a pick-up drum rotatably mounted in a frame, a windguard mounted at a free end of two lateral support arms, the two lateral support arms pivotably mounted at their other end to the frame, a crossbar having tines mounted at one end to the crossbar, the crossbar pivotably mounted to the support arms for allowing a range of free movement of the free extremities of the tines between an upper limit and a lower limit wherein two elongate flexible tension elements are connected at one end eccentrically to the crossbar and at their other end to the frame.

Abstract: The apparatus is a farm machine that inverts crop windrows using only the raking tines of a conventional rotary rake machine. The tines engage and move an existing windrow, and invert the windrow as the crop is being disengaged from the tines. The inverting machine accomplishes the inverting by imparting motion to the discharging crop that has a vector of motion that is in the same direction as the movement of the inverter machine. This causes the crop to move faster than the machine itself and inverts the windrow by pushing the disengaging crop over the crop that was previously discharged.

Abstract: A folding frame for a drawn implement such as a hay rake is disclosed. The frame includes cushion fold cylinders, a lift cylinder, and a windrow width cylinder. The lift arms actuated by the lift cylinder lift the frame wings and engage a selector valve, providing an open circuit to either the fold cylinder or the windrow width cylinder, or both. During folding, when the cylinders reach the cushion region of their stroke, the pressure in the hydraulic circuit increases, resulting in a change in the force applied to the selector valve by the lift arm. By careful adjustment, this change in pressure will adjust the selector valve so the hydraulic circuit is open to both the fold and windrow width cylinders. Consequently, the windrow width cylinders extend, keeping the frame wings from colliding with the main frame.

Abstract: A haymaking machine for windrowing forage includes a frame carrying several rotors connected to carrier arms which are articulated to the frame and which can be moved from a work position into a transport position. The carrier arms are made as two telescopic parts of which the second carries the corresponding rotors and can slide with respect to the first part to vary the position of the corresponding rotor. The first telescopic part of at least one carrier arm includes an additional guide section making it possible to increase the distance over which the second part with the corresponding rotor can move.

Abstract: The present invention relates to a hay making machine, particularly a windrower for plant matter, comprising a structure carrying at least one raking wheel. The latter is connected to the end of a carrying arm in such a way as to be able to pivot about a first axis and a second axis.

Abstract: The present invention relates to a haymaking machine including a chassis which carries several tedding and/or windrowing rotors. This chassis has lateral parts which can be folded upward for transport and/or setting down. A protection device which at least partially surrounds the rotors is connected to said chassis. This protection device includes lateral elements which can also be folded upward for transport and/or setting down.Each lateral element of the protection device includes at least one substantially straight section which is guided in such a way that it can move longitudinally in a bearing which is connected to the corresponding lateral part of the chassis so as to reduce the height of the machine in this position.

Abstract: This invention relates to the improvement of a new hay rake system that utilizes two separate wheel-type rakes which are substantially merged into one by mounting them to fold in for traveling and fold out for the raking position.

Abstract: An operational carrier for a wheel-type hay rake has an upper frame with one end for single point attachment to the draw bar of a towing vehicle. A lower frame is disposed beneath the upper frame and pivotally connected at one end to the upper frame. A first linkage is pivotally connected at one end to the upper frame and has an opposite end for attachment to the frame of the hay rake. The lower frame is provided with means for pivotally attaching an opposite end of the lower frame to the frame of the hay rake. Hydraulic means mounted on said upper frame has a piston rod connected to the lower frame for raising the lower frame to move the frame of the hay rake when said first linkage is connected to the frame of the hay rake in a substantially vertical direction from a raking position to a transport position.
