you know what else they care about? grease zerks (technical farmer thing I'll explain). these are them:
so there are over a million of them on all kinds of plows, tractors, swather things that eat the hay, you name it. if you use it to farm cows or plants it's got grease zerks. you use a grease gun with giant tubes of lube to squirt it into them like every 4 hours you use the thing that has them. this is the gun.
it's an enormous pain in the ass and it's always hot as crap and there are bugs everywhere when you do it. here's what I figured out on my own though. it's fake news. you don't have to do it. I've gone literally a month without grease gunning a grease zerk and nothing mostly broke. I'm pretty sure it's a scam from big grease.
