Tenneco put alot of $$$ in CASE to get it up to speed in the market. However CASE also shed alot of $$$ loosing lines, when they dropped everything except tractors. Thus going from a full line manufacture to a 1 line.
When you only have 1 line to market and R&D, your costs plummet dramatically.(your income does too!)
If IH, Ford or Allis-Chalmers had done the same in the 1970's, might this have changed thier future???
