Sorry I can't remember who all of you are.... But I wanted to let you folks know that in addition to what I said the changes were, there has also been a change to the tension idler arm. 2006 and newer have a gold metal colored one like the other hardware on the machine instead of the painted type the older ones have. I didn't get to inspect it well enough to see more than that. Also, they have new 'textured' fuel tanks. Same style, just textured. Another thing I noticed is that the discharge deflector is still basically the same, but does not point downward any at all. (I'd buy myself one of those if I ever used one) Also, to confirm... NO, they did not adopt the 'wide track' setup for the rear track width on the 60" units. So with the exception of the changes to the hydro system, it seems to be basically the same thing as the 2005's.
