Abstract: A support device, to be hooked up to a hitching device of a tractor: the support device includes a chassis 10 as a machine-welded metal structure which is fixed at 20 to the hitching device, and a platform extending cantilevered relative to the fixing device, the platform has an upper side 16 equipped at 160 to pre-position and center a box 40 to be supported on the platform, and a lower side 19 including at least one accommodating housing 191, 192 for cooperating with a corresponding protuberance 51, 52 of an add-on weight 50, intended to be supported under the platform to provide an anchoring in the shape of a “dovetail” type connection extending in the longitudinal direction substantially parallel to the direction of travel of the tractor.

Abstract: A main ballasting weight (10) straight from the foundry for a farming tractor, comprising upper faces and lower faces (11, 12), two faces (13, 14) oriented transversely to the direction of movement of the tractor, and two lateral faces (15, 16) parallel to the direction of movement of the tractor, said lower face comprising dovetail type means of connection (121, 122) to provide an anchoring with a secondary weight, said upper face forming an upper plate comprising a means of pre-positioning and centring (110) of a box (20) designed to be mounted on said main weight, said lateral faces (15, 16) being able to cooperate with lateral flanges (22, 23) of said box which are attached bearing against said lateral faces and having fixation orifices (150) able to receive fixation screws cooperating with said lateral flanges for the fixation of said box to said main weight.
