Using GPS on a tractor in order to draw sounds very complicated. I’m glad this farmer warmed POTUS’ heart.

He must be at least as thirsty for justice as we are!

Thank you for your answers!

While “precision ag” equipment is very sophisticated, it makes operating the machinery dirt simple. The tractor could offer levels of assistance all the way to working the field without human intervention, but as a buddy who works for John Deere puts it, “farmers LIKE to drive tractors!”. So a common mode is to engage the autopilot and let the GPS guid the tractor to make perfectly straight rows, then the farmer flips it off and makes the headland turn (180) and back on again.

This takes GPS precision greater than possible from the satellites only, and few people know that the largest Differential GPS Correction system is the John Deere StarFire system, which is more accurate than the one run by the FAA (down to 1 meter with typical 24 hour accuracy of 4.5 cm!)
