I've herd alot of people talk about double blade setups and was wondering if it would work with my mower. Right now I've got a JD GS30. I've got the original factory blades, factory mulching blades, and a set of gator blades. As far as the double blade setup goes, do you need certian or special blades or should you use just a high lift and a mulching blkade? Also, can you run double blades with the mulching kit in or is it better to just side discharge?
