Conveyor system (1) for forage bales (2) comprising driving means (3) for said forage bales (2) and dragging means (4) for said driving means (3) for moving said bales (2) along a conveying direction, and it is characterised in that said driving means (3) are rotatably mounted about a longitudinal axis ("Y") of said dragging means, said driving means (3) being susceptible to freely rotate about said axis ("Y") to permit the relative movement of the bales (2) with respect to said dragging means (4). The system prevents the breakage of tie threads, permits to auto-align the bales and permits the bales to trace curved paths with a very little rotation radius.
