Embodiment Construction

[0045] figure 1 and partially figure 2 9 to 9 show an agricultural machine 1 (here in particular a disc mower) having a working part 2 which is equipped with a backing plate 4 on its lower wall 3 .

[0046] These backing plates 4 are formed in the lower wall 3 of the working part 2 or are rigidly fixed together with the lower wall, and the backing plates 4 constitute a raised bearing area, each of which is equipped with a forming bush and embedded in the The wear-resistant member 5 on the backing plate 4 (embedded on its lower end surface).

[0047] Each bushing 5 has at least one front end 8 and front edges 9 (one front edge 9 on each side of the front end 8).

[0048] According to the invention, at least one front edge 9 , preferably both front edges 9 , of the bushing 5 have protrusions 12 , at least part of which enter into grooves 13 formed in the corresponding backing plate 4 .

[0049] The front edges 9 on both sides of the front end 8 are best seen in a front view (n...

Abstract

The invention relates to an agricultural machine with skids equipped with interchangeable liners. The agricultural machine is a disk mower, a swather or similar machine, resting at least partly in braced manner on the soil during its use and provided with a working element (2) and with skids (4) designed to slide on the soil. These skids (4) are formed in a lower wall (3) of the working element (2) or are integral with this lower wall (3), and each skid (4) is provided with a liner (5) having at least one frontal end and a frontal rim on each side of this frontal end (8). At least one of the frontal rims of the liner (5) of each skid (4) has a relief (12), at least one part of which penetrates into an indentation (13) formed in the corresponding skid (4).

Description

technical field [0001] The invention relates to the field of agricultural machines, in particular machines of which part of the weight is supported on the ground during operation by a support plate arranged in particular below the working parts. The invention has particular application to lawn mowers, such as disc mowers, or sun mowers, but is also applicable to other agricultural machinery which is hitched to a tractor and which, in use, is at least partially slidably supported on the ground. . [0002] In this context, the invention relates to an agricultural machine with a backing plate equipped with interchangeable bushings. Background technique [0003] A variety of agricultural machinery has functional implements, equipment or mechanisms, which are collectively referred to as working parts. When in use, they slide on the ground and are supported on the ground by at least one backing plate or at least one backing plate + bushing device. Generally speaking, they have M...
