I hear talk of a Toro G3 from a salesman awhile back on the phone. I go to Toro's website and see no G3. I Google it and see a 6000 series referred to as a g3. So, what exactly is a g3? Is it like a 3 generation thing? For those of you in the know with Toro. What kinda price am I lookn at for a 5000 or 6000 series Toro with a 52" deck? I really want a Kawa but I guess Kohler would do too. Thanks.
