Abstract
Folding heads for corn-shelling machines and/or combine harvesters which include a central portion extending along a main transversal direction and two lateral portions aligned with the central portion in a working condition of the head are provided. Folding heads may include drive elements for moving the lateral portions so as to pass from the working configuration to a folded configuration wherein the lateral portions are at least partially folded and overlapping the central portion. Each lateral portion may be operatively connected to the central portion by connection elements which may include a relative arm which connects each lateral portion to the central portion, wherein the connection elements include a first hinge defining a first rotation axis parallel to a longitudinal direction of advancement of the head and a second hinge defining a second rotation axis, perpendicular to the first rotation axis. Methods of making and using folding heads are also provided.
