This is an IMMENSE 1917 Avery Steam Tractor, on exhibit at our Agricultural Museum, here in Stuttgart, Ark USA. I heard they had to build the museum AROUND these behemoths, they have several. This is just PART of the wheel system, it is WAY taller than I am! I could just SEE the plow horses running in stark terror from these things chugging across our prairie! I probably would run!! This was taken November 2011, with a SanyoVPC-E2100.
