Yes, there is a Beach-Tech sign on the back of it. As a follow-up, the problem Saturday was apparently with a fuel line but it has been fixed and the machine is being used, but can only remove just so much on each pass.
As far as Dawn Beach seaweed goes, the first 4 weeks that I was there, it was minimal and mostly manageable by hand. The last 2 weeks, the volume increased but has now subsided again.
