Abstract: An agricultural wheel includes a body including a rim, and a semi-hollow-type tire including a flexible case including a sheath and a tread. The rim includes a seat section, suitable for receiving the tire, and a tool section, suitable for scraping the seed drill disc. The tread has a profile domed towards the outside of the tire. The case includes a first sidewall, close to the tool section, connecting the sheath to the tread. The sidewall extends radially or slightly inclined radially. The rim includes an intermediate axial section which connects the tool section to the seat section. The intermediate section is shaped as an axial stop for the tire which is form fitted with the first sidewall. The tire is mounted on the seat section by means of the sheath in an axially stressed state which maintains the first sidewall in contact against the stop.

Abstract: An agricultural tool includes a wheel body and a flexible tyre 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 tyre, and one of the end faces of the spacer has an axially protruding surface. The spacer is placed across the opening of the tyre such that the protruding surface engages the inner surface in an area of the portion corresponding to the bead.
