Thanks for your comment. I appreciate it. I spent a lot of time with the yard boss this spring tilling a lot of different stuff and I can tell you it's a great tiller. The main problem with it is you have to really work it to make it dig in unlike the Mantis because the engine on the stihl is not over top of the tiller head like the Mantis. They can do the same job but the mantis is definitely quicker at digging in.

I did not encounter any worms so none were harmed
