I'm not sure if this is a bug or not, or if it's a step towards ground creation, but I noticed that if you run the cultivator/plow past the fields edge with the cultivator or plow lowered, raise said implement and then drive over the same are again, the tractor will sink into the ground as if it's in the fields limits.
