Been cutting for 8 years. On my third 23 horse 60 inch deck. Got the new Triton, used all of last year and still not satisfied with it. It boggs down in moderate to thick grass. Had 2 ultra cuts and was satisfied with them. Now when ex mark came out with the new Triton you would have thought of an improvement, but it only got worse. Cant get no good answers from the reps. And yes Ive got the after market piece on the deck and my rpms are where they are suppose to be.
