Mixed results from this purchase but overall positive. You asked, so I'll tell you. The site was easy to navigate and I found what fit my Troy-Bilt Horse tiller easily. Ordering the products was easy but at no time did I see an estimated arrival date. It could have been 2 days or 2 weeks. Fortunately it was 3 days. The tiller tines did not fit out of the box. They original tines and hub were curved and these tines had a flat mounting surface which appears to be a newer design. You should either sell both styles or at least identify which models it fits (using the further mounting holes could work but would only have bearing on the 4 corners. I ended up grinding a curve in the mounting face which was a lot of work but effective. I had a better experience with the engine. Despite having a single page of instructions it mounted easily out of the box. I had an issue because this engine uses a larger bolt to mount the pully wheel and the bolt was too short for this application. I drilled out the pully wheel and bought a longer bolt and made it work. This particular model was too big to fit inside the protective tube bumper. If I had to do it over again I would buy the XR1450 for $70 more and which is used in current models and appears to fit within the bumper. All that said, I put oil and gas in the engine and it started on the first pull. Everything works as expected. More effort than I expected but the end results were great.
