So this is the thing, the lines plowed in the fields you find are actually pretty tricky to follow. At the edge, that is. Tractors aren’t great for turning circles and you see this reflected in the way real life tractors plow fields. One common pattern is ‘up down up down up down … then all around the edge’ this gives room for the tractors to turn around at the end of each plowing run.
Here’s what a typical field corner looks like now.
I would suggest changing that to something like this.
A bit of a gap in the corner, because they’re tricky, and no going up/down right to the fence.
