An agricultural rake including a frame, ground engaging wheels for supporting the frame on the ground, and at least two rotors each of which is driven in rotation about a respective vertical rotor axis and mounted to the frame by a folding linkage that permits folding movement of each rotor between a working position and a raised position. Each rotor has at least one ground engaging guide wheel mounted inwardly of crop engaging tines with a height adjustment mechanism permitting adjustment of the rotor operating height. For road transport, a control system automatically retracts each ground engaging guide wheel into the respective rotor in the raised position to reduce overall width.
