Abstract

The present disclosure relates to an agricultural machinery comprising: a main frame (14); a first sub-frame (18) movable with respect to the main frame (14) between a transport position and a working position; a second sub-frame (20) movable with respect to the main frame (14) between a transport position and a working position; a first hydraulic actuator (114) for moving the first sub-frame (18) between its transport position and its working position, the first hydraulic actuator (114) being part of a first hydraulic circuit (102); a second hydraulic actuator (116) for moving the second sub-frame (20) between its transport position and its working position, the second hydraulic actuator (116) being part of a second hydraulic circuit (104); and a hydraulic system (100) comprising a pump for providing the first and second hydraulic circuits (102, 104) with hydraulic fluid flow, the hydraulic system (100) comprising a first flow divider (112) for dividing the hydraulic fluid flow between the first and second hydraulic actuators, the first flow divider (112) being capable of coordinating the movement of the first and second hydraulic actuators (114, 116); a first recirculation valve arrangement configured to enable recirculation of hydraulic fluid in the first hydraulic circuit (102), when the first sub-frame (18) is in its transport position.
