Mine is a 2010 RZT 50. Recently, after mowing for a short while, when I disengage the PTO, it would not re-engage immediately. I'd have to ride around for a few minutes for it to kick in. For example, if I go into reverse and try to re-engage the PTO going forward, it would not engage immediately. I thought there's a short somewhere, but can't find any electrical short. Any ideas would be appreciated. Thanks.
