Anything that doesn't move much can have a cord. Cross country trains can have electrified rails.
.
Earth movers carrying loads up out of a pit, or the giant farm tractors that are now required to grow enough food for 8 billion people, run at 40% thermal efficiency so unlike a car, there is only slightly better than 2:1 efficiency to be gained. And are not convenient to run on a cord. You will need a MWh battery to take the place of each 400 Liters of fuel.
