摘要： A header for an agricultural vehicle. The header includes a header frame and an elongate sickle knife mounted along a leading edge of the header. The header further includes an actuator for reciprocally moving the elongate sickle knife in its longitudinal direction relative to the header frame between a first position and a second position over an intermediate position. At least one accumulator extends between the header frame and the elongate sickle knife to accumulate energy during a first movement of the elongate sickle knife from the intermediate position towards at least one of the first position and the second position, and to release accumulated energy during a second movement of the elongate sickle knife opposite to the first movement.

摘要： The present invention relates to cutting tools, in particular, to control systems for cutters such as vegetation cutters, especially hedge cutters or trimmers (10). Hedge cutters (10) frequently suffer in use from a problem of blocked cutting blades when they encounter a twig or branch whose size or density exceeds the capacity of the blades. We describe a vegetation cutting apparatus (10) having a plurality of cutting blades (11,12), at least one of which blades (11,12) is drivable by an electric motor. At least one driven blade (11,12) is movable between two predefined points of maximum travel. The apparatus (10) includes a control mechanism which causes a change of direction in the movement of the at least one movable blade at a point intermediate the points of maximum travel in response to an event sensed by the control mechanism.

摘要： Disclosed is a mowing apparatus, which includes a pair of first and second cutting members slidably superposed with each other, each of the members including a plurality of aligned cutting teeth; mechanism for moving the first cutting member relative to the second cutting member reciprocably within a predetermined range in the direction of the aligned cutting teeth at a substantially uniform speed; and a drive source for driving the moving mechanism. The moving mechanism includes a solenoid actuator having first and second coils and a plunger provided reciprocatingly movably between the first and second coils. The plunger is connected to the first cutting member. The moving mechanism further includes a switch alternately switches the first and second coils ON, thereby causing the first and second coils to become magnetized alternately to attract the plunger alternately so that the first cutting member to which the plunger is coupled is moved at a substantially uniform speed in accordance with the motion of the plunger.
