Midwestern Mecha Guardian 1

Usually when you see mecha they're defending a moonbase or patrolling a ruined cityscape, but what about the other 99% of the world? What about the small towns, the farms, the agricultural sector? In a world with mecha, why wouldn't your average farmhand replace their rusty tractor with a handy farm mech? Why wouldn't space nations want to keep their supply chains for troops and citizens safe? Such was the mindset that went into this image.
