I'm new to this forum and find this info so interesting, thanks guys! I grew up on the farm with ih tractors and one thing I recall that was interesting was my uncle was one of the head engineers for the tillage department in the Hamilton Ontario plant. So we got to test out the vibershank, viberchisel, and chisel plow cultivators. The interesting thing was when the farmers used this equipment but made suggestions for upgrades or changes, the engineers really listened and did there best to upgrade the product.
