I'm noticing a few conditions on the YT16H that are bugging me. The engine seems to run strong, but I've noticed that with the PTO on, the blade speed seems to come and go. It will be running smoothly, then randomly increase power/noise/blade speed for 10-30 seconds at a time. It cuts alright even at the 'lower speed' but I think it should be running at the higher speed all the time. Would a loose belt cause inconsistent power? My 16 horses might not all be there?
Related to that, it can't quite get the grass all the way up the bagger so it clogs
Lastly, after a solid 45 minutes or so of mowing, the engine will surge sometimes. Does overheating cause surge? Do I need to run with a bit of choke?
I'm hoping a splash of Marvel oil will help recover some engine power
