Hydraulic earth auger

Hydraulic drive

— the drive is based on a hydraulic system, the main components of which are a pump and a hydraulic motor. The pump, rotated by the main engine of the drill, creates oil pressure in the hydraulic system; due to this pressure, in turn, the hydraulic motor rotates. Such a scheme is notable primarily for its long service life, even under difficult conditions. That is why for heavy, dense soils like layered clay, it is recommended to choose hydraulic units. Another advantage is that the power unit (engine with pump) can be made separately from the work unit (hydraulic motor and drill), and both units can be connected with hydraulic hoses. Thus, the operator (operators) will not need to carry the entire structure, but only a relatively small and light working unit. On the other hand, motor drills with such a drive are more complicated in design and maintenance, have a very impressive weight, and are more expensive.
