Can someone exlpain the benefit of large squares? The only time I see them around here is the occasional truckload on the interstate, so I'm not familiar. One of the benefits of big rounds is being able to store them outside. Other than stackability for people with the barn space, I can't think of any benefit of the large squares. They sure look nice, but that only goes so far.
Easier to handle and transport, isn't a "wide load".
Better stacking in a shed or barn.
Can be fed in slices like a small square, doesn't require special equipment to break the bale down or unroll it for TMR mixers.
Less waste at the feeder since the whole bales doesn't have to be fed.
Better leaf retention.
Higher capacity baling.
I am sure there are more.
I don't buy into the thought of storing round hay outside, any hay worth baling is worth storing under cover.
