Bob,
Thank you for the info. Is a dual tire fork one with duelies on the front?
Does your fork have the flatter tires on it?
What kind of power? (diesel, gas, propane,etc)
I am looking at a 2wheel drive, 6000 lb with rough terrain tires. It basically is a tractor with the seat turned backwards. The gentleman selling it said you can always put chains on it. If you really need the traction. It is a late 70's with a Diesel engine for around $9000
