Abstract

The present disclosure relates to an implement connectable to a working vehicle. The implement (1) comprises an arm (2); an attaching arrangement (4) connected to the arm (2), said attaching arrangement (4) being attachable to a working tool (5); a locking arrangement (10) connected to the attaching arrangement (4) and configured to securely lock the working tool (5) to the attaching arrangement (4), said locking arrangement (10) comprising a hydraulic lock actuator (12); a first hydraulic circuit (40) configured to carry hydraulic fluid to a first hydraulic function (44) and to the locking arrangement; the locking arrangement (10) comprising a first safety valve (16) and a second safety valve (18) connected to the first hydraulic circuit (40), being configured to stop fluid acting on the hydraulic lock actuator (12) in the unlocking direction; the first safety valve (16) and the second safety valve (18) are connected in series.
