The thrower is attached to the discharge end of a baler in position to receive bales successively issuing therefrom. A pair of generally superimposed conveyors of the thrower operate at relatively high speeds compared to the speed at which the bales issue from the baler, and as the leading end of each bale enters the awaiting thrower, the high speed conveyors grab the bale and propel it upwardly and rearwardly toward an awaiting receptacle such as a trailing wagon. The upper conveyor is so mounted that it clamps down in a self-actuating manner against the bale as the latter enters the thrower and makes engagement with the propelling surfaces of the conveyors, such clamping action arising from the reaction force generated by the slowly moving bale contacting the rapidly moving surface of the upper conveyor.
