There were a series of talks at the Royal Society about Robot Farming a few months back.

This video, by the head of Harper Adams College, goes into a lot more detail:

Agricultural machinery size is now limited by train tunnel size for delivery.

Larger farm vehicles, although more productive per person are heavier and cause soil compaction, which then requires further treatments to fix. Mention was made of light robot tractors able to work wet fields earlier before they are dry enough for a heavy human tractor so extending they growing season. They show an example of a light weight tractor that can drive up and down on a wet field without turning it into mud.
