-
1. A device for mechanically clearing waterways, particularly ditches, comprising a king post assembly mounted on a vehicle, a vertically swingable multi section boom carried by the king post assembly, an hydraulically controllable mowings receptacle with a cutter bar positioned at the side away from the carrying point by which the mowings receptacle is connected to the boom which cutter bar can be driven by means of a driving mechanism mounted on the mowings receptacle and which driving mechanism can be controlled from the vehicle.
-
2. A device according to claim 1, characterized by the driving mechanism for the cutter-bar being a motor actuated by oil supplied under pressure.
-
3. A device according to claim 2 wherein the driving mechanism for the cutter-bar is mounted on the mowings receptacle.
-
4. A device according to claim 1 characterized by the mowings receptacle comprising a supporting beam and a cutter-bar interconnected by semi-circular bars
-
5. A device for mechanically clearing waterways, particularly ditches, comprising a vehicle, mounting means having a substantially vertical axis of rotation mounted upon said vehicle, a vertically swingable multi section boom connecting at one end to said mounting means, a receptacle incorporating a cutter bar pivotally connecting at the other end of said boom, a shaft providing the pivotal connection between said receptacle and the boom, said shaft being substantially parallel to said cutter bar, and a motor mounted on said receptacle and providing the force for driving the cutter bar, said motor comprising an oil pressure actuated motor.
-
6. The device according to claim 5, wherein said mowing receptacle is mounted to the multi section boom by means of a first shaft that extends parallel to the cutter bar and a second shaft that extends perpendicular to said first shaft and the cutter bar.
-
7. A device for mechanically clearing waterways, particularly ditches, comprising a vehicle, a mounting means pivotally mounted upon said vehicle, a vertically swingable multi section boom carried by said mounting means, a mowing receptacle incorporating a cutter bar connecting to the other end of said boom, a horizontal pivot means providing the means for connection between said boom and the mowing receptacle and extending at least substantially parallel to said cutter bar and the pivot axes of the multi section boom.
-
8. The invention of claim 7 wherein said mowing receptacle comprises a supporting beam having a cutter-bar spaced therefrom and interconnected by substantially semi-circular bars, said connecting means extending substantially parallel to said supporting beam and said cutter-bar.
-
9. The mowing receptacle according to claim 8 and further characterized by said pivot means including an additional means for pivotal connection that extends perpendicularly to said first pivot axiS and to said cutter-bar.
-
10. The mowing receptacle of claim 9 including a spring means attaching to said supporting beam and cooperating with said pivot means to stabilize the mounting of said receptacle to the boom.
-
11. The receptacle according to claim 8 and further characterized by a driving mechanism for said cutter bar, said driving mechanism being formed from a motor being actuated by an oil supply under pressure that is mounted on the receptacle.
-
12. A device for mechanically clearing waterways, particularly ditches, comprising a vehicle, mounting means having a substantially vertical axis of rotation mounted upon said vehicle, and vertically swingable multi section boom connecting at one end to said mounting means, a receptacle incorporating a cutter bar pivotally connecting at the other end of said boom, a motor mounted on said receptacle and providing the force for driving the cutter bar, said motor comprising an oil pressure actuated motor.
