180 hrs. Forgot to mention the 249F oil temp in direct sun mowing medium tough 12" weeds for an hour. This engine is very quick to cool compared with my DYT 4000. For instance stopping blades drops oil 4 degrees almost immediately and shade also has an immediate effect, about 5 degrees. Too bad Briggs is going under. They would have fared better with a better rep (more good engines).How many hours do you have on it now ?
