Abstract: A berry picker, especially for blueberries, is equipped with a plurality of picking units forming at least one row of picking units in a picking head movably carried by a mobile support chassis. Each picking unit has its own picking conveyor carrying a plurality of picking combs. Each picking conveyor is supported by its own picking frame. All the picking frames are carried by a mounting frame or carriage floatingly mounted on the mobile support chassis. Each picking frame is movably supported by the floating mounting frame or carriage for automatically lifting each picking frame individually by a respective first power lifter in response to an obstacle signal representing the ground condition. The ground condition signal is sensed by a ground sensor provided individually for each picking unit. The floating movement of the mounting frame is accomplished by separate second power lifters in response to further sensors or in response to a manual operator control.
