Improvements to trailers for the transportation of agricultural machinery of the type comprising a chassis (1) including, at one end, means for hitching it to the rear of a tractor, the said chassis being supported by at least two wheels (14, 24) located one on one side and the other on the other side of the chassis (1) and mounted freely on their axle (13), characterised in that it includes, on the one hand, means for adjusting the height of the axles (13) of the wheels with respect to the chassis (1) so that the latter can be lowered right down to the ground and, on the other hand, means for causing the said wheels (14, 24) to pivot when the chassis is lowered in order to lay them flat against the ground. <IMAGE>
