What about using a re-purposed treadmill to drive a tire on a tow mixer??
You could let the mixer down from a jack so that adequate pressure is applied to one of the drive tires or just up-end one end of the treadmill with a lever & fulcrum.
A treadmill ought to have enough umph to drive the mixer.
I mean, you had a good laugh at a 400 pound guy getting slung off a treadmill, right? :-)
Oh...
Me neither.
Anyway, everybody n their brother has a treadmill to get rid of for cheap or free and a little 3500w genny would drive it for pennies per load...
probably...
maybe.
or not. :-I
Just a thought.
