Abstract

A haymaking device for displacing mown crop includes a frame having a main beam which extends in a longitudinal direction and defines a longitudinal center 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, preferably rotatably driven about a rotor center line. The crop processing tool can be a crop displacing tool, such as a rake. The 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 center line, to the first side arm for movement between an operative position and a transport position. In the operative position, the first pivot arm connection is located at a larger distance from the main beam than the rotor center line of the first crop processing tool.

Dependent claims

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,
at least a first side arm located on one side of the main beam,
a first satellite frame which is rotatably connected to the first side arm about a substantially vertical centre line,
a first pivot arm which, in the region of a first pivot arm connection, is pivotably connected to the first satellite frame about a substantially horizontal centre line for movement between an operative position and a transport position,
a first crop processing tool which is mounted on the first pivot arm in such a manner that it can be rotatably driven about a first rotor centre line,
a second pivot arm which, in the region of a second pivot arm connection, is pivotably connected to the first satellite frame about a substantially horizontal centre line for movement between an operative position and a transport position,
a second crop processing tool which is mounted on the second pivot arm in such a manner that it can be rotatably driven about a second rotor centre line,
wherein in the operative position of the first and second pivot arms, the first pivot arm connection is located at a larger horizontal distance from the longitudinal centre line than the first rotor centre line of the first crop processing tool and the second pivot arm connection is located at a smaller horizontal distance from the longitudinal centre line than the second rotor centre line of the second crop processing tool.
