I am looking at getting a MF 1758, but want a loader with self-leveling. I see alo Quicke 180c has mount for a MF 1560 and MF 1660. Does the 1758 use the same subframe as a 1660? Or is there another manufacture selling in the US that has a loader with self-leveling system for the 1758? Also, I wish Massey would add the true 3rd function valve to the joystick. Thanks
