A crop take-up assembly having a rotatable take-up rotor with tines mounted thereon. A first guide assembly encloses the tines in an upper, forward and lower region, and defines a first set of guide tracks in which the tines are guided along a curved path. A second guide assembly encloses the tines in a rear region. The second guide assembly guides the tines into the first set of guide tracks during a reversal of rotation of the take-up rotor.
