My old Craftsman died and I decided to try a dealer Toro. Two models fit my needs and price range and, with the salesman help, I bought the PP20372 with the China engine over the other model with a B&S motor. Main reason...salesman claimed China motor had less plastic and better overall motor. Now I'm having second thoughts. We're talking Chinese made here. Anyone had a problem with this model or engine? Any little tips or tricks to keep it running for a few years longer other than the usual maint.? Any secrets to chopping leaves with this thing? I notice she seems louder than my Craftsman that had a B&S on it, is this normal for this engine?
