Sometimes first impressions can be valuable. I have a Ferris 3100Z with Vanguard 30hp that may be getting a different engine. The big concern I had going to the SCAG TT was ride quality. The first day when I was pushing the speed envelope, 12mph on my property, I noticed the difference. This AM I experimented mowing at more reasonable mowing speeds, actually slower speeds as I am working in very wet grass that is way past due for mowing. I was very pleased with the ride and feel confident that the ride will not be a problem at the normal speeds I mow at, more like 6-10mph. I would like to mow faster and plan to optimize my property for fast mowing with 61" decks. I expect to work up to 8-12mph but I don't think I have enough large, open, unobstructed area to mow at 14-16mph. I am confident that this mower will meet my comfort requirements. The major benefits I see with the TT vs the Ferris mower are: The deck and motor combo handle tall grass, especially wet tall grass very well. The 35hp Vanguard engine is a positive in my hilly environment where I occasionally need a ZT that can do a little "bushhoging". I like the fact that there are no gas tanks on the side of the mower that can obstruct my view or hit things. The 8.5 gal tank under the seat is all the gas I need for a days work and placing the weight low in the center stabilizes the mower on hills. I think this feature benefits me by increasing my ability to mow around objects safely. The SCAG TT has the feeling of being a mature product all the controls feel like they are in the right place and function with a minimal amount of fuss. About my only issue with the TT at this point is so far I am not getting the quality of cut I was hoping for. Obviously this issue will get better as I figure out how to set the deck up, which blades to use...I tend to mow too high often at 4.25-4.5" or even taller. Sometimes my dogs need practice tracking in taller grass, sometimes I like to let the grass get tall enough to make some seed. When I lowered the deck to 3.75 from 4.25" I got better results. I may need to mow at 3-3.5" to get optimal results. I am very happy with the new SCAG TT mower. I can see why this mower has the highest resale value.
