FIELD: agriculture.
SUBSTANCE: group of inventions relates to agricultural tools, in particular to a hydraulic control system for foldable agricultural tool. The hydraulic control device for foldable agricultural tool comprises a first hydraulic control system for controlling the transfer of weight to the tools for interaction with the ground, mounted on the fixed and foldable side sections of the frame. The second hydraulic control system is used for folding and unfolding the side sections. There is a hydraulic remote control that docks both hydraulic systems for controlling the sequence of operations performed by the first and second hydraulic systems. The first and second hydraulic systems have valves with mechanical adjustment for controlling the flow of hydraulic fluid to the various lifting, folding and lowering cylinders.
EFFECT: group of inventions enables to provide control of hydraulic system.
