Walnut trees are common on our farm, even invasive one might say. A particularly large one was unlucky enough to be caught dropping walnuts in our frog pond. It had to go because walnuts are poisonous to aquatic animals. So, we cut it down. It just so happens I have a friend with a sawmill and the facilities to process the wood.
In the course of a day, we lifted an entire walnut log, twice: once to load the cut boards on the trailer (above) and the pickup, and again to put them on a rack to dry (below).
