Farm equipment that increases the efficiency of farms

In today's industrialized society farmers use a lot of mechanical machines to plant and harvest different kind of crops. To represent that manufacturer buildings can produce "Farm equipment" and this farm equipment can be take as an input to farms to increase efficiency. This can be a new farm building that uses less workers and gives better output.
Farm equipment would probably have a recipe something like this "Mechanical Parts" + "Electronics II" + "Iron Plates".

i think farm equipment shuold take Electronics. not the tier 2 version. they dont have super advanced computers,really...

How about actual farming vehicles, like tractors and harvesters? And actual fields?
I think it needs a big overhaul. The current farm system feels like a placeholder.
