Abstract
This invention relates to a farm machine with a toolholding frame including a crosswise support provided with at least two rotors which is jointed to a coupling device by way of a pin. The crosswise support is made up of a central part and two lateral parts jointed to the ends of the central part by way of substantially horizontal pins. Each of these lateral parts is provided with a coupling device having three hooking points for connection to a rotor.
Claims17
A farm machine with a toolholding frame movable in a direction of advance, comprising:
- a crosswise support and a coupling device which are pivotally connected by means of a substantially vertical hinge pin, said crosswire support having means for connecting at least two rotors, each of said rotors having a support pin and being rotationally driven around said support pin to move hay lying on the ground, said crosswise support having first means for both pivoting the crosswise support around said substantially vertical hinge pin and stopping the crosswise support in several positions in which different angles are formed relative to the direction of advance, wherein the crosswise support comprises a central part which is connected to said coupling device and two lateral parts which are pivotally connected to the ends of the central part by means of substantially horizontal hinge pins, each lateral part being provided with a further coupling device for connection to at least one rotor of said at least two rotors, and each lateral part comprising second means for pivoting said lateral part upward around said substantially horizontal hinge pin, wherein said central part comprises a distribution housing, each of said lateral parts having a transmission housing comprising drive means connected to the corresponding rotor and a transmission shaft connected to said distribution housing.
