I guess it would also mean higher upfront price to make up for losses in servicing. And I guess farmers don't want that. The current situation is market driven and I guess "repairs will be more expensive/planned obsolescence" is more engaging than a higher price. And I think that's where a government has to intervene. Even if the situation is the one that suit manufacturers and customers (even if they don't admit it), it is not the best for the environment and collectivity in general, so regulation is in order.
