The only issues I saw with the English are in the quoted part. Ox is 1, Oxen is 2 or more. Also it should be "they don't ever get stuck in the mud" not never.Buffaloes as beasts of burden
Males of most buffalo breeds are suitable for heavy work, but they are slower than oxen and they tend to heat up more quickly because they have 90% less sweat glands than cattle. On road they are usually worked from evening to morning or under cloudy conditions. They are more suitable than oxens for tilling rice fields as they have strong and thick feet and they don't never get stuck in the mud.
It looks really good and there is NO way I could write something that well in a language that is not my native one.
Hope you feel better soon!
