On the basis of the performed study, it was concluded that the mechanical drill for deep planting (poplar) "3M" has a significant advantage over the hydraulic manual drill. The basic advantage is the greater working speed of the mechanical drill due to the greater power. The second advantage is its simple construction, which makes it significantly less expensive compared to all types of hydraulic drills used for this purpose. The maintenance costs of the mechanical drill have to be lower, and the maintenance itself is easier and more simple. The large dimensions are a drawback of this drill. Some of the drawbacks could be easily eliminated.
