A fact my vet told me about horns, antlers, hooves, fingernails and hair -all composed of keratin.
Looks like something you could winch around with a portable winch/ capstan, and a good wheel.
This just gave me a good idea. A large pneumatic wheel can easily bolt onto a tongue, independent of the tongue jack. That would increase the ability to move the chipper, I think. I don't know why I hadn't thought of that before. I'll tumble that idea around a bit.
I'm really a fan of moving the chipper to the brush, rather than the other way around, as chip mulch so often much more useful where the trees are, compared to where the truck is.
I saw a funky chipper on craigslist. A self-propelled, hydraulic feed wheel, drum chipper with an 18 hp engine. Fitchburg.
