I've always considered plagiarism to be the sincerest form of
flattery.

Go see the commercial machines, take notes, build. In this case you'll
prbablu want ot look for the twenty year old machines. bet today's
units are sized to do a 100 acres a day.

I'd take a look at riding lawn mower baggers also. You're doing about
the same as bagging leaves. Might be a hell-of-a lot easier to sort
off site. water sorting looks to be a natural for this. Again, copy
tried and proven ideas.

There's nothing wrong with reinventing the wheel, but your first one
won't be as good as what you can copy.
