The present invention relates to an apparatus for transferring agricultural products, for agricultural machines designed for the formation of a bale, which comprises at least one impeller rotor (2), which can be arranged between a pick-up drum of agricultural products, of the type of grass, grain, maize, hay, forage, and the like, and a chamber for the compression of the agricultural products, for the formation of the bale. Furthermore, the rotor (2) is facing a deck (3), for delimiting at least partially a channel (4) for transferring the agricultural products, which are pushed by the rotor (2), from the pick-up drum to the chamber. The deck (3) is coupled to a fixed frame (5) by way of at least two supports (6, 7) which can move on command. At least one first support (6) comprises at least one support pin (8), which is coupled to a first portion of the deck (3) and moved, in a corresponding guiding slot (9), by a corresponding actuator (10)； at least one second support (7) comprises at least one crank (11), which is coupled to a second portion of the deck (3) and rotatable about a rotation axis (A) that is perpendicular to the advancement direction.
