1. A mower comprising a support structure on which are articulated about substantially horizontal axes at least two mowing units each comprising a carrier frame carrying at least one cutterbar and a conveyor belt for grouping the mown products, wherein said mowing units can be moved about said substantially horizontal axes from a substantially horizontal working position into a substantially vertical transport position, wherein the conveyor belts are articulated relative to the cutterbars about conveyor belt axes that are substantially parallel to said cutterbars and the mowing units comprise means for automatically moving said conveyor belts relative to the cutterbars about said conveyor belt axes to bring the conveyor belts closer to the corresponding carrier frames and consequently to the middle of the mower when the mowing units are placed in the transport position,
wherein the means for automatically moving each conveyor belt includes a first rod and a second rod articulated with one another about a rod axis, said first rod being articulated on said carrier frame about a first axis and the second rod being articulated on said conveyor belt about a second axis, and a third rod articulated on the first rod via a third axis and on the support structure via a fourth axis which is offset relative to the substantially horizontal axis of articulation of the corresponding mowing unit on said support structure.
