Lake work, clearing trees off a dam. Press the arrows for some vids and stuff.
*Must* change it? I don't think I'd like that. There's some oldies around that work fine, and look great, especially wood fired cookstoves. Those are $$$ to replace.
Mik, in the second pic, the grapple set up looks like it would be ideal to take out smallish trees that are in a bad spot for felling, take em out vertically like a FB does, yeah?
