I'll know tomorrow or Monday if I won the bid on an old manlift out at work. I don't know a lot about the machine but it's sitting on what looks like 38" (?)Groundhawgs. When I first saw it, I could see a buggy with four wheel independently(sp) driven wheels. I figure I could build a frame for everything to hang off using maybe cylinders for the suspension. May be too slow though. More research will be needed if I get this thing. If it doesn't make a buggy then I can at least trim the trees around this place.
