Here's some of the features the $15,000 models DON'T have:
👉 Raise the container using a fork lift (not expensive hydraulics)
👉👉 Four legs can be raise to different heights – to use out in the field, on uneven surfaces
👉👉👉 Worth repeating, this cost ONE THIRD the price of other machines! And you get the same great results for happy, healthy pigs.
