The interaction process between the working tool of a collector and a fruit has been considered, as well as the process of hitting water-melons on various surfaces. A diagram of speed distribution when the working tool interacts with a fruit has been presented, as well as that of the area of expansion of plastic deformation after a shock impact on a fruit. The absolute and allowable increment speeds after a shock have been theoretically determined and justified. The parameters of the allowable speeds for variety “Crimson sweet” and for variety “Kholodok” have been theoretically found and the verification of the theoretical analysis was performed through experimental researches on an installation for determining the critical impact speed on a fruit. The comparison of the theoretical and experimental values of the limit speeds confirms the accuracy of the studies.
