In a world where nobody owns tractors and just leases them...
Tractors manufactured in the 1960s are still in regular use today, to a far greater extent than e.g. automobiles of that era. Although there are regular improvements, the core task of pulling implements across a field has not changed, and the same giant piles of steel that function today should still function decades from now. The portion of tractor owners and users who would welcome the dystopia you envision is minuscule.
