We have had our Vita Mix 5000 for several years. It is a very good machine. It came with the 64 oz. container and we have never had to use the pusher. There are wet blades and dry blades for this machine. The wet blades are designed to draw the ingredients downward. The dry blades force the ingredients upward. I have also read that the blades are not interchangeable between the 64 oz. and 48 oz. container. If you do buy the 48 oz. container, be sure it comes with blades.
