I had the Tri-cycler installed on my 62C before delivery. Also had the Tri-cycler on my 60" deck traded in. Love them both. My lawn is healthier for it.
I must add that there is a considerable incerase in effort to keep the deck clean throughout the year. The newer kits are better in that there are fewer nooks and crannies and less likelihood of rust developing. The 62C delivers a very good cut. No windrows or bogging. I cut about 3.75 acres of healthy tall fescue keeping it between 3.5 and 4 inches. With any mulching deck, you will improve performance by avoiding cutting dew-ey or wet grass. Make sure you are cutting no more than 30% of the total height of the grass.
All in all, it's worth every penny and the extra effort for a healthier lawn. Just my $ 0.04, adjusted upward for economic reasons.
