Just put on a new set of the Exmark Etreme blades because I did not have time to sharpen the high lifts. Well they did a pretty good job on a thick fescue yard that had went 10 days without mowing. The conditions were dry but they put a nice stripe on the yard and I noticed the clippings were etremely small (almost dust). I side discharge but use blades like this or gator type blades in the fall mostly but they did so well today that I may leave them on for a while. Not sure how they will preform when conditions are damp or high humidity. Any other reviews on this blade.? I would be interested in your opinions. Thanks. Cut was very smooth just like the high lifts in these conditions anyway.
