An automated mushroom harvester has a carriage adapted to be moved over a mushroom-growing area, a picking head assembly being mounted on the carriage. The assembly includes a pneumatic ram mounted for rotation about its own axis, the ram piston rod being non-rotatable with respect to the ram cylinder. A suction cap is mounted on the lower end of the rod, and control means is provided for the supply of air to and from the ram. The control means is operated to drive the ram in such a way as to maintain substantially constant the speed of the suction cap as it approaches a mushroom to be harvested, and to ensure the maximum energy of the moving parts of the picking head assembly is below 0.25 Joules, during that constant speed approach.
