Has anyone used the small tiller attachment for the Stihl FS 85. Does it compare to the Mantis tiller or others. Im looking to use this in my own beds and not commercially. Im going to buy a new FS 85 this year and also need a small tiller. I was going to buy the Mantis but thought I would save a couple hundred if I just bought the tiller attachment for the FS 85. My plans are also to buy the pole saw attachment for the FS 85 as well. Any thoughts.
