A folding head (4) for a corn-shelling machine and/or combine harvester comprising a central portion (12) extending along a main transversal direction (Y-Y) and two lateral portions (20, 22) aligned with the central portion (12) in a working condition of the head (4). The head (4) comprises drive means (44) for moving the lateral portions (20, 22) so as to pass from the working configuration to a folded configuration wherein the lateral portions (20, 22) are at least partially folded and overlapping the central portion (12). Each lateral portion (20, 22) is operatively connected to the central portion (12) by means of connection means (32) comprising a relative arm (34) which connects each lateral portion (20, 22) to the central portion (12), wherein the connection means (32) comprise a first hinge (36) defining a first rotation axis (R') parallel to a longitudinal direction (X-X) of advancement of the head (4) and a second hinge (40) defining a second rotation axis (R"), perpendicular to the first rotation axis (R').
