For the folks that said no on the interchangeable BS I'm just wondering why
Me too. Makes no sense. Especially for guys with hunting leases. Instead of packing a 10 ft collapsed pole saw, a 6 ft weedeeter, a 6 ft brush trimmer, a full size tiller, and the rest of mg gear on my atv, I carry one power head and 4 attachments which all collapse down to 4 ft pieces. One fuel can with same mixture.
Best part, I can store all the attachments in the garage and just the head and gas can in the shed reducing the gas smell in the garage.
