may want to check the cub cadet site under parts--enter 1572 model number
look under brakes--part 7 is the bracket that pushes in safety switch found under electrical--part 27 and 28.
I believe the original bracket that pushes in the switch has been updated to a better system. I have a 1772 and the bracket broke on mine which prevents the safety switch from being pushed in when parking brake is set.
sounds like someone wired around your switch.
