Help me find grammatical mistakes, ...any suggestion.........or any other mistakes?

Hurston used the mules as a symbol of Janie and Logan’s marriage, “ Ah needs two mules dis yeah. Taters is go.....” (Hurston, 27). She illustrates how Logan didn't see marriage in terms of love; he only saw it in terms of free labor. Logan feels that as they live together so they ought to do an equal amount of work. Logan makes work and treats her more like a mule than a wife.
