I love it. It's a LA120 which is the older brother of your D125, Twin V, hydro and 42 inch deck. And yes, I still love it. The only thing it has needed is gas, oil, plugs and filters. I have purchased different blades to experiment with over the years and some add on's just because I wanted them.
When I found this and other tractor forums, I thought I had made a mistake as most people bad mouth the entry level Deere's and told me the thing would be a pile of rust and dust after two years. They were very wrong. I only need to get two more years out of it as I am retiring and moving south. But now, I am considering bringing it with me.
I hope you get the same service and pleasure out of yours that I got out of mine. As far as the suicide knob, it's the first thing I would buy if I got a new tractor. It's the only way I turn my wheel. The other hand is freed up for a beer.......
