Yes there are flaws in all of them, or at least in some individual units of any line you care to mention. The worldwide economy has it's advantages and it's disadvantages. You can export designs and assembly processes to where materials ,labor and market are closest and most efficient ,but you have to deal with the local language and government and it's tax burden. Some of that is good some of it is bad. They are all in a competitive war with each other and the ammo they fire at the enemy is each individual tractor coming off the assembly line and the customer service given to it's purchaser. If they start firing duds into the market at any time they will be in trouble. After all it does not matter how good a JD model B was or a Farmall super C. You can't buy a new one of them even if it was the perfect tractor for your needs.
It is not "are they all perfect?" But "how many out of a thousand have problems?" and what does the company and dealer do about it if the one you bought has a problem of flaw? You could put up with a lot of flaws if they made it right on their dime, and didn't leave you hanging with a cash crop in the field.
