Not sure if this belongs here or on "Farm Tools", I'm guessing that this is some kind of planting implement. The tool incorporates a hand held upper end with a spring return plunger rod extending down ot the "digging" end. The lower end is a three fingered plug cutter, the plunger rod pushes thru the core cutter to eject the (earth ?) plug. Notice the "ear" projection, this to provide a push for ones foot. The tool is marked (cast iron) "PAT - Apld - For" "JKI" on one side and "J-R-Kovar" on the back side. Well made tool, Cast iron, steel and nice wood handles. Any ideas?
