Plunger type hay baler having a frame 1 forming an internal pressing channel 5 in which a pressing plunger 9 moves in a reciprocating movement, an intake orifice 6 through which hay loads into the pressing channel 5 and a loading chute 7 which connects to the pressing channel 5 at the orifice 6. A loader 35 which operates in synchronization with the alternating movement of the plunger 9, periodically introduces into the loading channel 7 basic loads and causes them to go from the loading chute 7 into the pressing channel 5. The loader 35 and pressing plunger 9 are respectively associated with a transmission system 32, 22, 25, 24, 27, 28, 30 for transforming a continuously circular movement of a driving crankshaft 12 of the pressing plunger 9 into an alternating circular movement of the driving pivot 28 of the loader 35.
