I sure agree with all the Lawnboy lovers. My dad sold them when I was a kid. The only problem was he never sold another to the same person!
I do have to throw in a word for another mower though.... 29 years ago we bought a brand new 5hp Briggs engine self propelled walk behind Yazoo. Other than a new engine after 26 years , it's still going strong. Oh, yaaaa, the belts need replacement every 10 years or so, but the rest of it is darn near indestructible. I'm not sure if they still make them, but you can still get parts....but the only part you'd ever, ever, have to buy from the factory would be the drive pawls that rub on the wheels to provide the forward motion. I've replaced them once. ALL other parts are hardware store, or make it yourself from common steel.
<edit> Just did some searching... idiot government! The Yazoo walk behind is no longer made, "Owners should not use the product if they own one." They do not meet the "stop blade in 3 second" law. However, not ONE injury from a Yazoo! <quote from CPSC website> " Neither CPSC nor the company is aware of any consumer injuries resulting from the lack of a blade control device on these mowers."
Looks like I'll have to make my own drive pawl. Maybe I'll need a set in 2019.
