Mower

A mower comprising:

• (a) a frame by means of which said mower is, during use, hitched to a pulling vehicle;
• (b) a cutting bar connected to said frame, said cutting bar comprising:
• (i) two rotary cutting elements and
• (ii) a housing located under said two rotary cutting elements, said housing comprising two cases and a brace element determining the distance between said two cases, said two cases and said brace element extending at least approximately in line one after the other in the longitudinal direction of said housing, each of said two rotary cutting elements being guided in rotation in an associated one of said two cases around an upwardly directed axis, said brace element being formed integrally with at least a part of one of said two cases so as to form a module which comprises a flange abutting a flange on the other of said two cases, and assembly elements, one part of which extends at the front of said housing and another part of which extends at the rear of said housing, said assembly elements comprising bolts which extend at least approximately appellate to said longitudinal direction of said housing and which form the only connections between said modules, said bolts rigidly but releasably connecting said abutting flanges of said modules and said other said two cases to one another and extending, as seen from above, at least approximately beneath at least one of said two rotary cutting elements;
• and
• (c) transmission means adapted, during use, to transfer rotational power from a source of rotational power to said two rotary cutting elements for driving in rotation each one of said two rotary cutting elements around the corresponding one of said upwardly directed axes.

In a cutting bar comprising a plurality of rotary cutting elements and a housing located under said plurality of rotary cutting elements, said housing being at least partially formed by cases and brace elements determining the distance between each two adjacent cases, said cases and said brace elements extending at least approximately in line one after the other in the longitudinal direction of said housing, sat least some of said plurality of rotary cutting elements being individually guided in rotation in an associated one of said cases around an upwardly directed axis, said cutting bar also comprising transmission means for transferring rotational power to said plurality of rotary cutting elements from a source of rotational power, an improved housing comprising modules each formed by one of said brace elements formed integrally with at least a part of the corresponding one of said cases, at each end of each one of said modules there being a flange which abuts an associated flange on an adjacent one of said modules, and assembly elements, one part of which extends at the front of said housing and another part of which extends at the rear of said housing, said assembly elements comprising bolts which extend at least approximately parallel to said longitudinal direction of said housing and which form the only connections between said modules, the corresponding bolts of two adjacent modules rigidly but releasably connecting the abutting flanges of said two adjacent modules to one another and extending, as seen from above, at least approximately beneath at least an associated one of said plurality of rotary cutting elements.

In a cutting bar able to be equipped with a plurality of rotary cutting elements and comprising a housing located under said plurality of rotary cutting elements, said housing being at least partially formed by cases and brace elements determining he distance between each two adjacent cases, said cases and said brace elements extending at least approximately in line one after the other in the longitudinal direction of said housing, at least some of said plurality of rotary cutting elements being individually guided in rotation in an associated one of said cases around an upwardly directed axis, said cutting bar also comprising transmission means for transferring rotational power to said plurality of rotary cutting elements from a source of rotational power, an improved housing comprising modules each formed by one of said brace elements formed integrally with at least a part of the corresponding one of said cases, at each end of each one of said modules there being a flange which abuts an associated flange on an adjacent one of said modules, and assembly elements, one part of which extends at the front of said housing and another part of which extends at the rear of said housing, said assembly elements comprising bolts which extend at least approximately parallel to said longitudinal direction of said housing and which form the only connections between said modules, the corresponding bolts o two adjacent modules rigidly but releasably connecting the butting flanges of said two adjacent modules to one another and extending, as seen from above, at least approximately beneath at least an associated one of said plurality of rotary cutting elements.
