The energy performance of material shredders varies and depends on many factors. Concerning the use of single-stage mobile shredders of fruit tree branches of a compacted garden, there are none at all. Therefore, the purpose of these studies was to determine the energy performance indicators of the branch chopper based on a generalized assessment. The obtained data analysis showed that an increase in the rotation frequency from 12 to 21 s–1 led to a rise in the specific work for the technological process execution from 3–5 to 11–15 kJ/kg. During an increase in the rotation frequency within a range from 12 to 19 s–1 with the supply of branches from 1.58 to 2.18 kg/s, the energy intensity of the process decreases from 0.632–0.727 to 0.536–0.721 kJ/kg. It is due to achieving the operating speed of the hammers necessary for the effective grinding of branches, reducing the time the material stays in the chamber, and increasing the degree of grinding. The energy capacity reaches its minimum value at the rotor rotation frequency range from 14 to 19 s–1 (depending on the material feed). In contrast, the sieving capacity of the recutters will coincide with the productivity of the flow of crushed particles. Labor costs for obtaining 1 kg of chopped wood at the upper limit of throughput capacity of 1.58 kg/s are 10.6 kJ, and the energy intensity of the process is 0.539 kJ/kg.
