For example, wind pumps had improved significantly by the 1880’s. Metal wind pumps had been developed that were able to reach water hundreds of metres underground, and they only needed oiling once a year. Other new machinery made ploughing the land and growing crops easier. For example, seed drills were developed which were able to automatically plant seeds at the correct depth.
