Mantis tillers are perfect if the ground you have is the consistency of
Quaker oatmeal in the box. Nice. Fluffy. No clumps. No rocks.

But then, if it's that good of soil, what does one need with a tiller? A
tiller is for breaking up hard caked soil, or mixing soil that has sat all
winter. The Mantis is far too light for that, and just bounces along like a
Chihuahua on too many lattes.

MHO only.
