Oxen were commonly used in rural New England in colonial days for plowing, pulling logs, moving big stones and so forth. Not sure if they were used elsewhere. They’re not smart like horses and they don’t move fast but they are exceptionally strong. Where I used to live still has a lot of farm parcels from the 1600’s. They look very strange on a map given they are very long and very narrow,the reason being it was hard to turn oxen around when plowing so parcels were laid out in a way that maximized use of oxen. Modern day farmers of course own multiple such parcels so as to get configurations that make sense for modern equipment. Oxen were even used to move houses and other structures to new sites.
