Great for prepping the garden beds each spring.
Cut my yard work time in half this season. A little pricier than I hoped but the quality justifies it.

Well balanced and easy to maneuver around obstacles. Would recommend to anyone considering the Troy-Bilt Super-Bronco 208cc 16″ CRT Rear Tine Tiller #21D-65M8B66.
Tore through compacted soil with no trouble at all.
