Types of machines and units for extraction of trees and shrubs

Abstract

This article analyzes the structure, operating principle, technical indicators, and efficiency of PZU-1, KOP-2, and Tree Spade machines for digging tree and shrub seedlings along with their roots. Based on a comparative analysis of the machines, the advantages and disadvantages of each unit and the optimal conditions for their use were determined. The results of the study show that the hydraulic Tree Spade is the most efficient technique for large trees, while PZU-1 and KOP-2 are economically acceptable for small and medium-sized seedlings.
