Query: Go Mantis

Bought the Troy-Built cultivator last spring, used 2 times (briefly),worked well. Third time, the pull start broke. Replaced. Second tiller broke after two uses, same problem. The Troy-Built site had many complaints of tillers breaking after a couple of uses.We had a used Mantis cultivator which I gave to my dad after 30 years of use and it's still going strong. Forget Troy-Built, go Mantis.
