I am looking at getting the sthil yard boss with the aerator, de thatcher, and flower bed tiller attachment. I live in southern ca and most of my lawns are around 900 - 3600 sqft. I would not be using it on every yard mostly just spot and maybe a hole yard every now and then depending on how it works. my question is for small spot thatching and aeration is there something else i could use as a kombi? I am getting the kombi with the hedge trimmer and could get the tiller attachment for my edges. Dont whant to spend 4 grand to buy an aerator and a thatcher dont need them?
