The current supreme court is very unlikely to rule for an individual against a large company.

The Supreme court since FDR has been very resistant to role back the role of federal government, they have no problems smacking down state laws, but when it comes to rolling back federal laws or regulations well....
So here it would be determinative on which "side" the federal government chooses, or if the federal government stays silent which silence IMO is probably the most likely outcome for the federal government.
If they stay out of the fight, I think Deere Loses. If the federal government defends Deere then I think it is more 50/50
