what were the advantages of having no human being on the animal farm

In Chapter Three, we learn that the harvest is more of a success than Mr. Jones and his men ever accomplished, despite the fact that the tools are not well suited for animals to use, especially without the animals rearing up on their hind legs. The pigs supervise the others but do not participate in the manual labor. With the “parasitical human beings” out of the way, the animals enjoy a feeling of abundance for the first time. They have more leisure, and their food tastes all the better for their having gathered and portioned it out themselves.
