Haymaking device

A haymaking device for displacing mown crop, comprising:

• a frame having a main beam extending in a longitudinal direction and defining a longitudinal centre line, and at least a first side arm located on one side of the main beam, wherein the side arm carries at least one crop processing tool
• wherein at least a first crop processing tool is mounted on a first pivot arm, in the region of a first pivot arm connection, is pivotably connected, about a substantially horizontal centre line, to the first side arm for movement between an operative position and a transport position, wherein, in the operative position, the first crop processing tool is substantially located between the first pivot arm connection and the longitudinal centre line.

The device according to claim 30, wherein the pivot arm extends substantially at right angles to the longitudinal centre line.

A haymaking device comprising a frame having a main beam extending in a longitudinal direction and defining a longitudinal centre line, and at least a first side arm located on one side of the main beam, wherein the first side arm carries at least a first crop processing tool, wherein the first side arm is movable between a transport position, in which it extends substantially along the main beam, at a first angle to the main beam, and an operative position, in which the first side arm extends sidewardly from the main beam, at a second angle, larger than the first angle, wherein at least a first crop processing tool is mounted on a first pivot arm which, in the region of a first pivot arm connection, is pivotably connected, about a substantially horizontal centre line, to the first side arm for movement between an operative position, in which the crop processing tool can be active, and a transport position, wherein the first pivot arm is mounted on a first satellite frame which, in the region of a rotational connection, is rotatably connected about a substantially vertical centre line to the first side arm, wherein the first satellite frame is mounted at the end of the first side arm and is provided with a support wheel.

A haymaking device for displacing mown crop, comprising a primary frame part with a hitch for hitching to a tractor, wherein the frame with the hitch defines a longitudinal centre line of the device, which longitudinal centre line is parallel to the direction of travel or movement in the operative position, wherein the device further comprises two secondary frame parts, located on both sides of the primary frame part, which are connected to the primary frame part and are each provided with a first and a second crop processing tool, wherein the first and second crop processing tools are connected to the secondary frame by a first and a second pivot arm, respectively, for movement between an operative position and a transport position by a pivoting movement about a substantially horizontal pivot centre line, wherein, in the operative position, the first and second pivot arms extend in substantially opposite directions from the secondary frame part.

A haymaking device comprising a frame having a primary frame part and a front end provided with means for hitching to a tractor, and comprising four crop processing tools, wherein the frame of the haymaking device comprises a longitudinal centre line which is substantially parallel to the direction of travel, wherein two crop processing tools are located on both sides of the longitudinal centre line, in operative position behind each other with the front one of each pair being outwardly staggered with respect to the rear one of said pair, wherein the rear crop processing tools are each mounted on a respective rear, first pivot arm which is mounted, via a first pivot connection, on or near the free end of a first frame arm which extends per se freely rearwardly in a floating manner, substantially parallel to the longitudinal centre line and which, during use, is located at an intermediate distance from the longitudinal centre line, when viewed in a direction transverse thereto.

A haymaking device for displacing mown crop, comprising a primary frame part with a hitch for hitching to a tractor, wherein the frame with the hitch defines a longitudinal centre line of the device, which longitudinal centre line is parallel to the direction of travel or movement in the operative position, wherein the device further comprises two secondary frame parts located on both sides of the primary frame part, connected to the primary frame part and each provided with at least, wherein the secondary frame parts are connected to the primary frame part via a parallelogram mechanism active in a horizontal plane, for movement between an operative position at a distance from the primary frame part and a transport position near the primary frame part whilst maintaining their orientation with respect to the longitudinal centre line.

A haymaking device comprising a frame having a central, primary frame part, the main part comprising a main beam extending in longitudinal direction, and a longitudinal centre line, and two side arms extending sidewardly on both sides of and from the central frame part and each carrying at least one crop processing tool, which crop processing tool is connected to the respective side arm by means of a pivot shaft having a substantially horizontal pivot centre line in order to be pivoted between an operative position and an upwardly pivoted transport position, wherein the device further comprises a hitch for hitching the device to a tractor, and support wheels for supporting the frame in the operative position and the transport position of the device, wherein the support wheels are mounted to the ends of the side arms and are each rotatable about a substantially vertical centre line, and wherein the device further comprises setting mechanisms for setting the position of each support wheel with respect to the longitudinal centre line in at least one oblique position with respect to the longitudinal centre line.

A haymaking device comprising a frame having a central, primary frame part, the main part comprising a main beam extending in longitudinal direction, and a longitudinal centre line, and two side arms extending sidewardly on both sides of and from the central frame part and each carrying at least one crop processing tool, which crop processing tool is connected to the respective side arm by means of a pivot shaft having a substantially horizontal pivot centre line in order to be pivoted between an operative position and an upwardly pivoted transport position, wherein the device further comprises a hitch for hitching the device to a tractor, and support wheels for supporting the frame in the operative position and the transport position of the device, wherein the support wheels are mounted to the ends of the side arms and are each rotatable about a substantially vertical centre line, wherein the device further comprises an adjusting mechanism for adjusting the support wheels for the side arms into different oblique positions with respect to the longitudinal centre line.
