Abstract: A carrier for coupling loader arms to an implement of a work vehicle includes a pair of brackets coupled by a cross-rod. Each bracket includes an inner wall spaced apart from an outer part. At least one of the inner walls defines a latch slot. The carrier includes a latch mechanism movable between latched and unlatched positions. The latch mechanism includes a latch plate having a retaining flange with an engagement surface, a pair of lock pins and a pair of latch receptacles associated with the brackets. When in the latched position, the latch mechanism has the lock pins received in the latch receptacles and the engagement surface disengaged from the one of the inner walls. When in the unlatched position, the latch mechanism has the retaining flange passed through the latch slot and the engagement surface engaged with the one of the inner walls.

Abstract: The tool carrier disclosed herein has a locking device with a low degree of complexity, a low diversity of parts, and a high degree of reliability. By the completely automated locking process, the setting up of the tool on the tool carrier is considerably simplified for the operator or the driver, since neither has to leave the cabin any longer in order to lock the tool. The actuation of the setting up and holding devices by the tool during the setting up of the tool ensures that the locking device is used only if a tool is also set up. An erroneous movement of the lock into its locking position due to vibrations or by a movement of the tool carrier or the front loader without a set-up tool is effectively avoided.

Abstract: 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).
