摘要:
An agricultural machine including a frame capable of being coupled to a tractor, which frame comprises hinge means, adjusting means and one or more frame beams which are pivotable about a relevant first pivot shaft, of which frame beams at least one is carrying at least one working member, characterized in that a relevant frame beam is pivotable about a second pivot shaft extending substantially parallel to the first pivot shaft and at some distance therefrom, and that the adjusting means comprise an adjusting element bridging the first and second pivot shafts, by means of which adjusting element , upon energizing, a pivotal movement about both pivot shafts takes place.

An implement for laterally displacing crop lying on the soil, which implement comprises rake members (4, 5, 11, 12) that are driven mechanically so as to be rotatable about upwardly orientated axes, which rake members, seen in the direction of travel, are arranged in at least two groups of at least two rake members, said groups being disposed one behind the other, the outer rake members of each group rotating in opposite directions, the distance between the axes of rotation of the outer rake members (4, 5) of the leading group being smaller than the distance between the axes of rotation of the outer rake members (11, 12) of the group of rake members disposed therebehind.

The invention relates to an implement for displacing crop lying on the soil, comprising a frame and at least two rake members (2) which are each suitable to be driven about respective, spaced-apart axes of rotation (7), each rake member (2) being provided with a number of rake tines (5) which are pivotable about a respective axis of rotation, while at least one rake member is provided with a support carrying the rake member during operation. The implement further comprises hinging means (13) with the aid of which one rake member can be folded up on top of the other.

The invention relates to a control cylinder (1) comprising a housing (2) accommodating a movable piston (3) that fits the inner walls of the housing (2) and is provided with a piston rod (4), said piston (3) dividing the housing (2) into a first and a second chamber (5; 6) which are each provided with respectively a first and a second aperture (7; 8) for supplying a medium, such as e.g. oil, to the chambers or discharging same therefrom. The control cylinder (1) is further provided with connecting means (9) that connect the first chamber (5) to the second chamber (6) during a predetermined period of time and/or across a predetermined length when the piston (3) is moved in the housing (2) via respectively a third and a fourth aperture in the first and the second chamber (5; 6), thus permitting the medium to flow freely from the first chamber (5) to the second chamber (6) or vice versa.

The invention relates to an implement provided with a number of crop working members (14, 29, 30) rotatable about respective upwardly orientated axes, which crop working members are arranged in one or more groups (28, 22) each consisting of at least two crop working members for forming, in the folded out operative position of the implement, at least one row of crop working members orientated transversely to the direction of travel, while at least one group is fitted to a frame (1) so as to be pivotable forwards or rearwards relative to the direction of travel, from the operative position into the folded up position, and pivoting means being provided, so that at least one of the crop working members of at least one group is pivotable, for the purpose of reducing, in the folded up position, the length of that group relative to the direction of travel, while, in the folded up position, at least one of the crop working members has pivoted through an angle of less than 180°, preferably less than 160°, for the purpose of reducing the length in the folded up position.
摘要:
The invention relates to a method of adjusting an agricultural machine, in particular a tedder, having a range of two or more working members which, in the operative position of the machine, are disposed in side by side relationship in the direction transverse to the usual direction of travel of the machine, at least a range of two of these working members being moved sidewards relative to the direction of travel, the orientation of this range relative to the direction of travel remaining unchanged. The invention also relates to an agricultural machine by means of which this method can be applied. The invention furthermore relates to a method of crop handling.
摘要:
A construction for processing crop residues lying on the field, such as hay, comprising at least one carrier element which is pivotal and drivable about an at least predominantly upwardly directed shaft, to which working members (1) are attached via arms (2, 16), a working member (1) being provided with a connecting member (4) which is secured to an arm section with the aid of a clamping member, whilst the construction includes further connection means (7, 11, 19 - 28), with the aid of which a working member (1) can be adjusted to a finite number of positions relative to an arm section (5, 17).
