Its time for a new turf tiger both of our ztr's are pushing 2000hrs.. Last year I demoed the 31 kohler efi and was not totally impressed. I think I had a bit of sticker shock and may have been looking for too much.. The dealer brought to my attention that my old scag tt ( advantage ) is still a good machine to begin with, so the new one my not have the wow factor. I guess I saw his point.. So I'm sure I'm staying with a Turf Tiger but I'm all over the place with motor options. That 31 efi is scary, looks like their is a lot of stuff to go wrong it that I would not know where to start with as far as service. The briggs looks very simple which is nice but a little worried about the fuel and engine life span.. The briggs is 10k the kohler 12.5k, and one dealer has a demo kohler with 130hrs for 10.5k although it looks like a rough 130hrs if you get my drift. So any advice would be great, I'm all over the place on this.. My machine's rack up around 20 running hours each a week. I was thinking fuel may not play to much apart unless it hits 5 bucks a gallon again.. Also does anyone one know of anything new for the TT in 2010.. Thanks any comments are appreciated..
