In harvesting fruit, individual limbs of a tree are vibrated at their natural frequency, or a harmonic, so the fruit is removed therefrom. The limb is clamped firmly in a V-notch holder with a gate resiliently held in place so the limb is not damaged when the vibrator is vibrating the limb, or when the limb, at its natural frequency, is vibrating the holder.
