Does anyone run one of these? I hear a lot of people say they're quite good for what they are, but I'd be interested to know how much you could typically shift in a day. I've asked the bloke who posted this video, but I don't know if he'll understand English, and I can't speak Swedish!
They are good for swampy terrain, because of the wide belts.
Apart from that I feel that the 4 wheel atv has filled the niche that the Järnhäst used to occupy. They can pretty much do the same stuff and are a lot cheaper ( Järnhästen costs about 15.000$ just for the front part)+ they can move fast, when needed.
The Järnhäst only moves at walking speed, and a slow walk at that.
Gets on your nerves after a while.
So I'd say; cute but anacronistic!
I looked at the Iron Horse many years ago when I was just a firewood guy. Too expensive and too limited, especially if you are trying to make some money and value your time. Like Stig suggested an ATV is much faster for the task and more useful for other roles as well and half the cost.
In that first video he certainly isn't minimizing his "footprint" with those big wide skid trails needed to operate his set-up. My Kubota with a Farmi winch could very easily operate on those trails with 4X the load and 4X the speed. My Kubota can also do a dozen other useful things.
