When I worked on the commercial vegetable producer, the equipment necessary to do it right was astounding. This particular tractor is a two wheel drive John Deere equip with Garmin GPS on the top of the sun shade.
Mr. Howard always made sure people were planting with the two wheel tractors because the four wheel drive ones were too hard to turn real sharp at the end rows. Here we were planting 5 rows per bed, three beds per pass. The blue bar that is going up to the tractor over his head is a pesticide applicator boom. It has nozzles that help spray an application of herbicide after the seeds are submerged under the soil.
GPS equipment allowed for so many projects and task to be completed any day or night. We did not have but a few tractors that had GPS. Those were mainly the planting and dish harrow tractors. The pesticide appicator rigs and fertilizer spreaders would just follow the tractor tires from the perfect rows of the planter.
