ABSTRACT:
A front loader coupling apparatus for a front loader having masts attachable to mast mounts of a tractor, and booms, boom cylinders and braces. The front loader coupling apparatus includes a first coupling device provided on the masts and mast mounts, a second coupling device disposed above the first coupling device, a stand device connected to the masts, and a brace connecting device. The brace connecting device includes a receiver for receiving a cross rod of the braces. The receiver has a fixing device for fitting on the cross rod from above when the masts are attached to the mast mounts, and a support for supporting the cross rod from below when the cross rod is uncoupled from the fixing device. The fixing device and the support define a space therebetween for enabling forward parallel movement of the cross rod.
