It could probably be broken down to ship UPS, but I'm wondering if it might be easier/less expensive to break it down, then build a, maybe 30" X 30" X 36" tall crate to stand everything up, banding it together, and wedging so it doesn't shift, or fall over, then ship by truck. Weight has a lot to do with the cost of shipping, but so does floor space on a truck, especially shipping that far.
I bought quick attach head, and bucket for my little Bobcat a few years back from Worthington Ag. parts, and that's how they shipped it, and in a crate about that size. Pretty sure it came out of the Iowa yard, and here to central Ohio, and delivered to my door, shipping was $200.00. Crate and all, it probably weighed 250 lbs.
I do know freight company's do have shipping calculators. So that might give you an idea of what it would cost.
One problem I can see with having both blades on at once, is the lift mechanism. Looking at yours, then going to the IH online parts store, it's hard to tell, but it looks like there is only one rock shaft arm on the right side. If it had two, like on the left side, each blade could be lifted/lowered independently. With only one, one of the blades would have to be pinned in the raised position, while using the other.
Just some food for thought...
