摘要：
A front loader arrangement (12) with a mounting frame (16) and mounting mast (18) is proposed, wherein 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). In order to facilitate coupling of the mounting mast (18) to the mounting frame (16), it is proposed that a hydraulic system (85) be coupled to the hydraulic cylinder working chamber(s) (90, 96) and include adjusting means by which the hydraulic cylinder (24) can be brought into a floating position when the hydraulic fluid supply is decoupled from the hydraulic system (85).
