More specifically, I have a Deere XT140SB (string trimmer with the split-boom to operate different attachments) and I was wondering if I can use attachments of other brands on it. For instance, could I use the Stihl hedge trimmer attachment on my JD? Or could I use the Shindaiwa power-broom attachment on my JD? I really like the trimmer, it's just that Deere doesn't have too much to choose from in that area, and I'd like to increase my arsenal of tools but am trying to spend wisely (by not having to buy a whole new unit). Thanks.
