I'm looking for a good used plow and I stumbled upon this one on Craig'slist. I've looked at a few different new ones and this one looks unique. ...but I don't know if it's good or bad unique. Anyone know what kind it is? It appears to have a a blade that sits flat on the concrete. The seller thinks it weighs well over 100lbs. Is it worth the $75 asking price? ...and would I have any trouble pulling it with my 28hp? This would be my first plow so I need to get it right.
