Abstract: An apparatus for cutting vegetation is disclosed. The apparatus comprises a first and second cutting mechanism for cutting vegetation. The first cutting mechanism is configured to cut vegetation from an original height to a first height. The original height is a height greater than a height reachable by the second cutting mechanism. The second cutting mechanism is configured to cut the same vegetation from the first height to a second height, after the first cutting mechanism has cut the vegetation to the first height.

Abstract: A turf care device having an implement for performing a turf care function. The turf care device has a module for determining its position relative to the turf. The turf care implement is controlled based upon the position of the turf care device.

Abstract: A drive arrangement for a hand-guided working machine for agriculture, forestry and horticulture applications. The drive arrangement comprises an electric motor, a DC power source for electrical energy, and a control apparatus for the electric motor which is fed from the DC power source. The electric motor has a specific, in particular linear, characteristic curve between the electric current which is consumed by the electric motor and the rotational speed of an output shaft of the electric motor. The control apparatus has current-limiter which limits the current which flows through the electric motor to a maximum value in order to protect the electric motor against overloading. The control apparatus limits the current consumption of the electric motor in a range of low rotational speeds to values which are considerably smaller than the characteristic curve values which are given for these rotational speeds by the characteristic curve of the electric motor, as a function of the rotational speed.

Abstract: A double knife stubble cutting machine is provided for cutting stubble after a harvesting action into three separate pieces including a standing stubble piece and two cut pieces. The device comprises a frame having a center section and a pair of wing sections with the wing sections being pivotal about a horizontal axis upwardly to a transport position. The frame defines a tool bar across the full width of the frame which carries a pair of sickle knife support bars downwardly of the tool bar and arranged so that one sickle knife is forwardly of and upwardly of the second sickle knife. Both knives are open and free from support elements between the knives so that the cut material can be discarded back to the ground after cutting without any transverse movement or blockage. The harvesting action therefore allows the minimum amount of straw to be taken by the combine harvester so that the standing stubble element is cut into three pieces of equal length.

Abstract: A conventional header of a combine is modified by the addition of a second sickle knife positioned rearwardly of the pan of the header. The second sickle knife is mounted on a bar which is connected to a pair of arms extending under the pan to a forward end pivotally mounted just behind the conventional sickle knife of the header. The arms and the second sickle knife can thus pivot upwardly and downwardly and are mounted on suspension springs carried on the frame of the header. A simple drive from the conventional shaft of the header is connected through a belt to a drive wobble box carried on the second sickle knife at a position partway along its length.

Abstract: A monofilament line for a rotating string trimmer has a main body portion of a generally circular configuration. One or more sharp longitudinal cutting edges are integrally formed with the main body portion and protrude from the main body portion at an angle selected to cause controlled flex and asymmetrical drag on the cutting element, as it is rotated by a rotating string trimmer. This causes a torsional rotation of the free end of the line as it is rotated; so that the main body portion of the cutting element first strikes the object to be cut, followed by contact with the sharp cutting edge. This configuration is selected to cause cleaner cuts of grass and the like, with less shredding of the cut ends of the grass blades. In addition, larger vegetation such as weeds and small stalky shrubs may be efficiently cut without abnormally high wear of the cutting line.

Abstract: The invention relates to rotary mowers driven from below. According to the invention, shafts (18) and wheels (23) have at least their operational dimensions approximately identical, and alternate wheels (23) take two different positions in relation to the shafts (18). Moreover, when one of the disks (5, 6) is inclined in relation to an adjacent disk, the wheel (23) of the disk most inclined toward the front is farther from the disk (5, 6) than the wheel (23) is from the adjacent disk (5, 6). Moreover, the housing (4) comprises a sliding member (30) which at least partially closes the front part and/or the lower part of the housing (4).

Abstract: An attachment for forming standing straw snow traps comprises sickle blade, a curved guide and a support frame for mounting the attachment on the harvesting machine so that the sickle blade extends forwardly of, above and generally parallel to the machine's sickle blade over a short length thereof which is covered to prevent cutting of the crop. The attachment is connected to the reel arms of the machine for common height adjustment therewith. The curved guide directs the cut heads of the crop onto the collection draper of the machine. The attachment can be pivotaly mounted or mounted on scissors linkage from the cover.

Abstract: A frame assembly mounted in the windrow discharge area on a swather or windrower on which a plurality of horizontal assemblies, are mounted thereto. On these assemblies are mounted fraying and cutting blades. These blades are operated at a required speed to fray and distort the tips of the stubble and/or cut and reduce the length of the straw of the standing stubble so as to ensure that the supportive strength of the straw is not exceeded by the weight of the swath or windrow placed upon it. This will eliminate any distortion or buckling of the remaining conditioned standing stubble straws. A windrow delivery plate is mounted on the swather frame assembly within the windrow discharge area. This plate assures delivery of the windrowed material onto the swath support fingers which effects a gradual release of the windrowed material onto the remaining standing frayed and conditioned stubble directly behind the frayer conditioners track of travel in the field.

Abstract: An apparatus and method for controlling the growth of unwanted plants, such as weeds, volunteer plants, and the like, which project upwardly from a cultivated crop growing in a field, comprises providing an agricultural vehicle having a cutting bar thereon. The cutting bar is positioned at an elevation slightly above the uppermost portion of the crop, and the agricultural vehicle is piloted over the field, thereby cutting the upwardly projecting portions of the unwanted plants at a point thereon slightly above the uppermost portion of the crop, thereby arresting the growth of the unwanted plants, and facilitating the mechanical harvesting of the crop.
