What parts fail first usually?Under 200 bucks you are essentially buying a disposable piece of junk so it really doesn't matter. The mower will last a couple of years . Yes Briggs still makes some decent engines but at this price point you are buying the bottom of the line Chinese engine . Look for something with at least a solid handle and mower deck. The engine whether it's a Briggs or something else will last a few years. I think you will find nearly ever mower in this range is made by a company called MTD no matter what the brand . Good walk behind mowers start at around 500 US dollars
