5 Stars My Experience


Tim from NJ wrote (April 15, 2016):

I do recommend Agri Supply for your farming needs. I had a small mechanical problem that developed on this product, and Agri replaced it 1 year after the warranty expired going above and beyond their warranty obligations. Their commitment to customer satisfaction is first rate.
