What are there for tricks to keeping the mower deck on the 'x' 500 series tractors so that it doesn't shut down when going in reverse. I know they claim this to be a safety feature, but I was wondering what others are doing to hold the engagement lever in place so it doesn't pop out when you go in reverse. My only solution so far has been to jam the rubber key chain holder between the lever. This works ok but can be a pain to get set just right. Does anyone have other neat tricks? Thanks!
