John Deere, the company that makes green tractors, is in trouble because it makes fixing tractors too hard for farmers.
The government thinks it's unfair because farmers have to pay lots of money to fix broken parts on their tractors.
This means farmers can't harvest their fruits and vegetables as quickly, which means they could lose money..
This is like if you couldn't fix your bike yourself and had to pay a lot to get it fixed at a special shop!
