Anyone here built a grass clippings collector for their garden
tractor? Something that would fit on the 3-point hitch and probably be
driven by an old lawnmower motor (vertical shaft) since they're a dime
a dozen.

I'm wondering about the blower part in particular. My first thought is
that something like the impellor used in a shop dust collector would
work well, but perhaps experience says other wise?

Any shared experience or speculation welcomed.

Thanks,

The blowers in the old air cooled VW bugs moved one bodacious amount
of air because they were large diameter and so had high peripheral
velocity at engine RPM's You might want a screen to keep
twigs, golfballs and small animals from making that BRANNNNGGGGG
noise in the blower.

Fresh cut grass is kinda sticky and it can build up. You'll know
that if you've ever cleaned a mower deck with an air chisel. A good
design might be an induction system where a blower creates a
high-velocity jet that aspirates the grass clippings without them
going thru or even near the blower.
