You can still find pull behind combines from the 1960's and '70s
for around a thousand dollars. So I don't know if these Chinese
machines make any sense. They would take up less storage room.
And they are a novelty.
If I could find one of those little ones, I think I'd add a radio controlled
remote control system, and do my combining from the porch!
I think farm equipment is going to change very radically in the
present future once veteran farm boys return to their farms with
their UAV and UGV experience. We'll see.
(The little one in the first post I've seen advertised at $1900 minus shipping)
