A mast coupling arrangement for mounting a front loader to a work vehicle, the mast coupling arrangement comprising: a mounting bracket mounted at a proximal end of a mast of the front loader; a mounting frame defining first and second connection points (150, 152; 156, 160) and a load point, the mounting frame being connectable to the work vehicle a first mast connector configured to removably couple the mounting bracket and the first connection point (150; 156) of the mounting frame when the front loader is attached to the work vehicle; a load element mounted to the mast and, when the front loader is attached to the work vehicle, being in load transferring contact with the load point of the mounting frame, wherein the mounting bracket is configured to rotate due to gravity when the first mast connector is removably coupled to the first connection point (150; 156) of the mounting frame such that the load element is in load transferring contact with the load point; and, a second mast connector configured to removably couple the mounting bracket and the second connection point (152; 160) of the mounting frame when the front loader is attached to the work vehicle; wherein the second mast connector and the second connection point (152; 160) of the mounting frame are separable when the front loader is attached to the work vehicle; wherein the load element is configured to positively align the second mast connector, the second connection point (152; 160) of the mounting frame, and a connection bore of the mounting bracket only when it is in load transferring contact with the load point; characterised in that the load element is a multi-sided bar, and the load point of the mounting frame is a multi-sided notch having complementary sides configured to engage at least two sides of the bar in surface contact; and wherein the multi-sided notch is located on the mounting frame between the first (150; 156) and second (152; 160) connection points. a mounting bracket mounted at a proximal end of a mast of the front loader; a mounting frame defining first and second connection points (150, 152; 156, 160) and a load point, the mounting frame being connectable to the work vehicle a first mast connector configured to removably couple the mounting bracket and the first connection point (150; 156) of the mounting frame when the front loader is attached to the work vehicle; a load element mounted to the mast and, when the front loader is attached to the work vehicle, being in load transferring contact with the load point of the mounting frame, wherein the mounting bracket is configured to rotate due to gravity when the first mast connector is removably coupled to the first connection point (150; 156) of the mounting frame such that the load element is in load transferring contact with the load point; and, a second mast connector configured to removably couple the mounting bracket and the second connection point (152; 160) of the mounting frame when the front loader is attached to the work vehicle; wherein the second mast connector and the second connection point (152; 160) of the mounting frame are separable when the front loader is attached to the work vehicle; wherein the load element is configured to positively align the second mast connector, the second connection point (152; 160) of the mounting frame, and a connection bore of the mounting bracket only when it is in load transferring contact with the load point; characterised in that the load element is a multi-sided bar, and the load point of the mounting frame is a multi-sided notch having complementary sides configured to engage at least two sides of the bar in surface contact; and wherein the multi-sided notch is located on the mounting frame between the first (150; 156) and second (152; 160) connection points.
