Fit perfectly on my JD-450B, started smoothly and without any lag, very happy with its performance. I had the previous starter rebuilt twice in one year and end up having to replace it only six months later. Just buy it, its such a huge pain to take it off and put it back on, you don't want to do it more than you need to.
