A whole crop harvesting and/or separating apparatus (1) for use with grain or seed bearing crops such as wheat, barley, pulses and the like. The apparatus comprises a first rotor (2) and concave (4) and a second rotor (6) and concave (8) arranged so as to define a substantially S-shaped path for a crop in use of the apparatus to pass along. The first (2) and second (6) rotors are driven in opposite rotational directions. The first concave (4) comprising a first threshing portion (10) having a plurality of radially extending crop engaging bars (12) spaced apart in the direction of rotation of the first rotor (2) for threshing, vigorously, of a crop in use of the apparatus. The second portion (16) of the first concave (4) and the second concave (8) comprise a plurality of spaced apart crop rubbing bars (18) inclined with respect to a radial direction. These crop rubbing bars (18) are formed and arranged with the first (2) and second (6) rotors so as to convey the stalk portion of a crop in use of the apparatus along the S-shaped path in a substantially non-stalk breaking manner whereby a maximum of "long" straw passes around the concave path uncut. A straw breaking chamber (22) or baler may also be provided for the further processing of straw exiting the second concave. A multi-use wheeled undercarriage is provided with onboard hydraulic drive raising/lowering means.
