The purpose of the study was to substantiate promising directions for the creation of manual vibrators capable to improve the productivity of berries' harvesting in shrub plantations of various types based on the history of the creation in Russia of technical means for berry harvesting from bushes. The subject of the research was the technological process of interaction of the oscillating fork with the fruit-bearing branch. Everywhere the berries' picking of currant, gooseberry and honeysuckle, dog rose for a long time traditionally was carried out manually. However, since the middle of the last century, people began to use various devices not only to facilitate this process, but also to significantly increase the labor productivity. In the first models of commercial machines for the berries' picking, we used individual manual vibrators for each berry picker and lightweight mobile catchers. With the advent of high-capacity berry harvesters, we gradually ceased to use the technique with manual vibrators. New technologies and materials allow today to create more advanced manual vibrators for use not only in the homestead land, but also at group work on small commercial currants and other small fruit crops plantations, successfully competing with combines. Modernization of machines of this type, working without tractor, will have a positive impact on the environmental situation in perennial plantations.
