Your responses have been just great. I now flatter myself that I am pretty sure I know what a zero turn mower is. The next thing I need to look up is if I can get this option with a small tractor/mower. That is the product that I have to buy for my new farm. I will only have about 4 acres of lawn area, and it is in a fairly rolling country side. I am making an assumption from your comment rhonda42, that you see them on golf coarses, that I might be able to get the functionality in my size of product.
