I have a Shindaiwa T-230 trimmer. I think I read that you can add a hedge trimmer attachment to the T-230 (part # 78700)??? Called the dealer and they said you would have to go with the split boom system. I'd rather not spend $500, compared to $225. Has anybody done this. Edit: Just found in a search that a couple of people have done it. I guess some dealers don't know about it.
