Welcome to Sears.com To say I'm not happy is a huge understatement I checked the oil before the initial startup and it was fine. It's still fine, but the engine is seized. I was moving some dirt with the blade on the back when the engine started to smoke and sound bad. I killed it immediately and allowed it to cool. When I tried to restart it, it won't even turn over. It's a Kohler engine and the tractor is built for Sears by Husqvarna.
