My neighbor has 11 acres that is letting me pull some trees from. There are a number of willow oaks some 100 ft high and 4ft+ trunks on them. My son want to take them feels it would be a challenge.. Im not sure of the BTUs for willow oak and if its not a high end wood I dont want to spend the effort. There are alot of other oaks on the property, so I can take them. The willow oaks are monsters and will produce alot of wood.. so anyone know what the BTUs are per cord
