Original engine was Kohler 277CC, 9 hp. I now have an 16hp Duromax and, yes I have tried loosening the motor mounts for a belt I bought on Ebay and had the 2-20694 pt# on it. I discovered that it was about a 45" length and I am needing +/- 47". The Landmaster belt on AMAZON WANTS 150.00. Seems a bit much compared to all the other brand UTV belts. The problem is that a lot of these vendors do not publish the belt dimensions. So you have to purchase by brand name utv which is sketchy at best.
