I looked into gator mulching blades and was told by the dealer that the reason these blades were designed this way was to eliminate the need for a mulching kit. Also there was no need with these blades to run doubles. Sorry to be repetitive but I really want to get some info before I spend a couple hundred bucks on these. Would I benefit from these blades with a mulching kit and WHERE can I find a mulching kit for a Wright Stander I can't seem to find a place to order one for my machine if I need to. Thanks again for all your help.
