Beschreibung
Zusammenfassung:	The invention discloses a tractor oil way control valve block which comprises a control valve block body used for controlling conduction of oil. An oil duct I; the seventh oil duct is parallel to the first oil duct; the second oil duct is horizontally formed in the bottom of the first oil duct; the outer wall of the control valve block is provided with a regulating valve A for sealing the sixth oil duct; the eighth oil duct is parallel to the sixth oil duct; an oil duct 9; an oil duct III; an oil return joint is arranged at the end part of the fourth oil duct; and a regulating valve B for controlling the conduction of oil is arranged in the oil duct V. The device has the beneficial effects that the flow direction of oil liquid is adjusted through the oil channel in the single control valve block so as to improve stretching and contracting of the oil cylinder and adjust the height of the suspended farm tool, operation is convenient, reliability is high, whether an oil way is in a strong pressure state or not c
