I know the "big guys" don't like the tractors for mowing and I hope I don't catch too much heck for bringing this up. One thing I didn't like about the Exmark was the tendency (sp) to tear up the grass if you aren't careful. I know there is a learning curve as far as operating ZTRs, but I've talked to some experienced ZTR operators who say they even sometimes tear up the grass if they are in a hurry or just not thinking. The scary thing for me is that it only takes a second of not thinking to tear up the grass. I can only imagine what some picky customers say about that. This is where the AWS tractor might have an advantage since both drive wheels turn at the same time (Or at least I think they do on a AWS). I know on my JD LX 176 I never worry about tearing up the grass, I don't even have to think about it. Also, when winter comes, the tractor could be used for snow removal and as a possible back-up to a plow. I know the ZTR would probably mow faster than a tractor but I would think the fact that the tractor would be easier on the grass would be an advantage. Thanks for putting up with all of my questions, Joel B.
