Pruning trees is one of the most laborious processes in fruit growing. The level of mechanization, electrification and automation of caring for fruit trees is high, but a number of technological operations are carried out manually. The use of manual labor when pruning tree branches leads to a decrease in the productivity of workers and makes their work ineffective. The use of a manual electrified tool will improve the efficiency of the technology of detailed tree trimming. The existing Russian secateurs have disadvantages that prevent their wide introduction into production. These drawbacks are the use of asynchronous electric motors and an electric current source of increased frequency, large mass and overall dimensions. Foreign analogs of secateurs have improved mass and dimensional indicators, but have a high cost. Taking into account all the mentioned disadvantages, electromechanical secateurs based on a linear electric motor are offered, which have the following set of properties: low power consumption, easy maintenance, high operational reliability, small weight and overall dimensions, high speed. These advantages of the secateurs are achieved by using a linear electric motor. The main advantage of the linear electric drive is the lack of transmission, it is easy to manufacture, reliable in operation and has a high speed. The main parameter for calculating the linear electric motor is the cutting force of the branches. Fruit trees have a certain hardness, which depends on the temperature and humidity of the environment. For successful trimming of fruit tree branches, the optimal combination of the mechanical characteristics of the cutting pair and the linear electric drive is necessary.
