Im very happy with my 990. 40Hp and some big tires to make use of it. I have about 65 hrs on mine to date. It sure makes the neighbors drool. They seem to find plenty of projects for my little tractor as well.
I like the beefy simplicity of the 990. And the price was right.
I suppose most folks are looking to get into a hydro model, which have more bells and whistles. I like them myself, especially the new 20 series. Great machines.
