Puzzle number 8, I think.

[Radio]

It's been so long since I've done a puzzle I don't remember which number we are on, but I think 8 is about right.

So, what is this thing? What does it do? (and yes it's real)
24 hour rule, let everyone play.

Some sort of harvester?

Looks to me like a vacuum seed harvester.

And the answer is: It's a DIRT ZAMBONI!! :jitter:

Actually it's a peat moss harvester. Which is pretty close to being a dirt Zamboni.
