Bulldozers. They push down hedges.
Dairy farm, or crop farm? Dairy farm could not be near as big without refridgerated tanks for the milk, and machines to do the milking. cropfarms - bank credit so they can buy more and more land and bigger and bigger tractors.
Where to start, well there is the combine harvester, the 24 row auto till planter, the wide area sprayer (herbicide, pesticide and liquid fertilizer). There are just so many.
