WHEEL FORMING AN IMPROVED AGRICULTURAL TOOL

A tool (1) for an agricultural machine comprises a wheel body (3) including a hub (71), a rim (73) and at least two spokes (75) each mutually connecting the hub (71) and the rim (73). At least one opening (78) is formed between the two spokes (75) and the rim (73) and has a closed outline (28). The tool (1) comprises an accessory-forming part (2) having a profiled portion (23) of shape generally corresponding to said closed outline (28), and a generally surface portion (21) which terminates the profiled portion (23). The profiled portion (23) is inserted from one side of the wheel body (3) into said opening (78) by sealing the latter through shape cooperation. A fastening set (24) ensures the holding of the part (2) in a final position in which the surface portion (21) comes flush with the spokes (75), at least in the vicinity of said outline (28).
