Provided is a front loader assembly (12), comprising a mounting frame (16) and mounting mast (18). The mounting mast (18) can be coupled to the mounting frame (16) and can be decoupled therefrom. Furthermore, a loader arm (20) is connected to the mounting mast (18) for being pivoted vertically by a hydraulic cylinder (24) extending between the loader arm (20) and the mounting mast (18). The hydraulic cylinder is provided with cavities (94, 96) on a piston rod side and on a piston bottom side in a dual function manner, and is provided with a device used to bounce the front loader arm (20). The device comprises a hydraulic fluid reservoir (82) capable of being connected with a control valve (84), and the control valve (84) can be controlled by load pressure. In order to make process of front loader assembly (12) easy, the front loader assembly (12) is provided with an adjusting mechanism. Under the condition that hydraulic supply is disconnected, the hydraulic cylinder (24) can be sent into a floating position through the adjusting mechanism. The adjusting mechanism comprises a stop valve (90). The stop valve (90) is provided with a first switchover position and a second switchover position (108,110), wherein in the first switchover position (108,110), fluid connection flowing through the stop valve (90) can be established between the cavities (94, 96) on the piston bottom side and the piston rod side.
