They do look neat.
Sorry, maybe I am idiot, but why? Unless you are out in the woods and can blow chips everywhere I don't see what you gained? You still have to have a box, or a truck that you have to move?
Maybe I am missing the whole point, just asking.
Andy, track chippers in europe nearly outsell wheeled versions. If your doing cros country powerline work, working on railroads, want to leave the chips on site, or are working a clearence job, a tracked chipper is invaluable. Probably not the most practical for domestic / residential work though.
I've used some biggies...
In Albemarle Co. VA you need to have 2 acres to get a building permit so it seems like you can usually find somewhere to "broadcast" chips when you make the price insentive right, Ive always wanted to put my chipper on tracks.....
I had a couple of Gravelys and I liked them. Chips were extremely fine, even on palm fronds. Another chipper I found that matches them for extreme fineness of chips is the Morbark 2070XL. A lot can be packed in a small box when the chipper makes all the chips the size of a dime or smaller.
A guy around here had recently bought a brand new Bandit 95? on tracks. Never saw it but it would be nice to have. It would be really nice if you can get a low profile trailer and just leave it on the trailer to chip into the truck, or remove it and put it where you want it.
He actually just brought it back though with under 100 hrs, the remote control kept malfunctioning, he went through 4.
This is a guy with a mini k-boom log truck too, 4x4, he fits a nice niche doing firewood mostly.
