摘要： PURPOSE: To eliminate danger to damage a connecting rod or a driving member by providing a support body structure, which is extended orthogonally to working direction, and providing a safety system which can rotate a working tool behind an obstacle. CONSTITUTION: A mower is linked through a 1st chassis 4 to a connector 2 of a tractor 3, and joint relays 9, 11, 12 and 13 are arranged so as to form a deformable parallelogram. A 2nd chassis 14 and its working instrument 15 can be matched well with ruggedness on the surface of the ground. A safety system 43 prevents support body structure 17 from being rotated backward to a support body structure 18 around a relay 21 composed of a shaft 20 and a U link 31 and rotates the support body structure 17 and the working instrument 15 backward to the support body structure 18 because of obstacle and a limiting member 57 limits its rotating angle.

摘要： PURPOSE: To prevent the deformation of a supporting beam or a reinforcing member at a broken place by providing the rear connecting part of shoes with such a connecting member in which the rear part of each shoe travels backward to be removed from a cutting rod at the time of operation. CONSTITUTION: At the time of operation the cutting rod 23 slides on the ground surface 25 in the state of being butted to a shoe 24 and the abrasion of the part 57 of the shoe 24 is remarkable. Unless the abraded shoe 24 is replaced at a fixed time, the thickness of this part 57 becomes insufficient and the plate 40 of the shoe 24 is broken at this place. In a mower continues advance in the direction of an arrow 13 in this state, the tip edge 58 of the rear part of the broken plate 40 is caught by the ground surface 25 to remove the rear part of the broken plate 40 from a connection member 52. As an opening part 51 is made large enough to allow the branch part 54 of the member 52 to pass through, the plate 40 is simply removed.

摘要： PURPOSE: To form a beautiful hay line even at a curved part by providing a hay collector with a supporting shaft to be freely rotated to a chassis, connecting the supporting member at a position deviated from the advancing direction of the machine and fixing the supporting shaft within a horizontal plane while working. CONSTITUTION: A supporting shaft 17 provided with a cam 22 for drive is freely rotated to a chassis 1 during work, this supporting shaft 17 is connected through a connecting means to a supporting member deviated from this connecting means in the advancing direction of the machine, and the position of this supporting member 31 is fixed within the horizontal plane of the connecting means during work. Thus, the supporting member 31 is always positioned behind the supporting shaft 17 and automatically turned toward the moving direction of the machine during work.

摘要： A mower comprising at least one mowing unit 1 provided with a cutting bar 2 on the upper face 8 of which are placed a plurality of cutting elements 5, 6, and 7 mounted to rotate around axes 15 directed upwardly with the aid of a plurality of shafts 9, 10, and 11 guided in rotation in a housing 4 of the cutting bar 2. A support structure 3 is placed at a certain distance above the cutting bar 2 and is connected to the cutting bar 2. The support structure 3 includes a beam 28 extending crosswise to the direction of advance of the mowing unit during use. The beam 28 is connected to a strut 29 extending downwardly in the direction of a cutting element 7. The strut 29 is connected to the shaft 11 by a bearing 132. The bearing 132 includes a cylindrical guide 31, 32 the axis of which is merged with the axis 15 of the shaft 11. A connecting device 35 connects the strut 29 to the beam 28. The connecting device 35 includes a joint 36 having an axis 37 directed at least approximately perpendicularly to the plane containing the axes of rotation 15 of the cutting elements 5, 6 and 7.
