This may sound like a dumb question, but would it be better to run mulching blades rather than the standard blades that comes on my mower? I have a JD 737 w/ high rise blades, and I have a few lawns I do that grow so quickly that I am always leaving more clippings than I would like to see. What would you suggest? Stay w/ the standard high rise blade? Use mulching blades? Doubles? If I were to go to doubles, would that cause much more wear and tear on the mower? For my own lawn, I cut it every 5-7 days at 3.5 or 3.75. It looks really nice, but the clippings drive me crazy. Any suggestions would be much appreciated.
