I started cutting firewood today. Pulled out my grandfathers old saw rig after having the blade sharpened. Cuts like butter now. It's so much faster than using a chain saw to cut firewood. I haven't found any other saw rigs like this one around. The only other cord wood saws I have found hang from the 3 point hitch arms and operate by the PTO. This one rests on a trailer axle and is a pull behind. I don't think it has ever had any real blade protection on it. The only guard above the blade looks to me like it's a tire fender off a trailer.
