Abstract
An agricultural tool includes a wheel body and a flexible tire with a hollow chamber and an inner surface around this hollow chamber; a circular opening on the chamber; a pair of beads bordering this opening; and a spacer at least partially tubular with two axially opposite end faces. Over one portion corresponding to one of the beads, the inner surface extends frustoconically by widening radially outward of the flexible tire, and one of the end faces of the spacer has an axially protruding surface. The spacer is placed across the opening of the tire such that the protruding surface engages the inner surface in an area of the portion corresponding to the bead.

A kit intended to form an agricultural tool from a wheel body or a roller support, the kit comprising:
- a flexible tire having a hollow chamber and an inner surface around the hollow chamber, the flexible tire further having a circular opening on the hollow chamber and a pair of beads bordering the circular opening and by means of which the flexible tire is mounted around the wheel body or the roller support, and
- a spacer at least partially tubular with two axially opposite end faces,
- wherein at least over one portion corresponding to at least one of the beads, the inner surface extends generally frustoconically, by widening outward of the flexible tire, and one at least of the end faces of the spacer has at least one axially protruding surface, the spacer being shaped in such a way as to be placed across the opening of the flexible tire in such a way that the protruding surface is able to engage the inner surface in an area of said portion corresponding to the bead, and
- wherein the bead has a circular groove open on the hollow chamber and said area comprises the circular groove.
