Hello Yvette, I am afraid that you can not use your tiller to grind rocks or roots. You will have to clear all that sort of stuff out before tilling. The rocks will mess up your blades and your tiller if you try that too much. You can mulch with a lot of different things. There are some good discussions on mulching on other pages on the garden web. You might check those for some good advise....Good luck....DT

Is it a mini-tiller like a Mantis?

It is very small. My Dad says that his friend's Mantis is
a little bigger, but not buy much. This is a RYOBI.
The engine size is: 25.4 cc
Engine out put is: 1.2 HP
Does that make any sense?

TIA
