"Don't buy their stuff" is exactly the right answer. You need to do your research before you buy big ticket items. It may not be true in every sector, but Deere has plenty of competition.
Do you seriously expect other companies not following suit? People need lawnmowers, so this can quickly turn into the same situation we have with the inkjet printer market.
So the customer is 100% to blame then?
Please tell us - if you were buying one of these, would you specifically research how the fuel gauge works? Be honest.

No, that's not the answer. It only applies to those people who have time and energy to spare to do that reasearch. I'm not talking just farming equipment, but ordinary items such as a vacuum cleaner or printer.
If you're low income, work 2 jobs, single parent, get home at 23:00 broken tired, want a meal but your fridge just broke down and everything is spoiled inside, you don't spend 2 more hours doing reasearch. You clean it, go to bed hungry, call repair in the morning (optional, if your hopes are high), and when they tell you it's not repairable, you get the first new fridge you can afford in a 10 min online search while on the bus/train/tram being late to work.
Reasearch, self-repair, is for wealthy people.
