From age 14-18 I lived on a farm in Pullman, WA – USA. I still enjoy visiting working farms to smell the smells and see what’s growing.
“The spear- or harpoon-type haymow forks often employed a hollow or slotted cylindrical body with a solid point at the end and hinged barbs to skewer a load. The spear (or harpoon) was lowered to the wagon with its barb(s) retracted and then plunged into the loaded wagon. Extending the barbs prior to lifting retained a surprising amount of hay on the fork. Other designs offered different methods to retain the hay for lifting, but they were similar in the job they performed.”
