This seems like a great idea. Wonder why JD didn't design it this way in the first place - is there any downside?
there IS a downside, you can't have frontend weights on with the loader anymore. That is enough to keep me from doing it since I will probably never have the pto on my tractor and want to be able to hang the frontend weights. Otherwise I think it is good solution to your problemI wrapped chains on both sides and pulled at the same time. To set the 4X4 blocks, bring the loader down onto them slowly so you don't bend the tubing, it just needs to set on it with just enough pressure to hold it in place. You have to watch as you pull to make sure you have the tension correct for both sides. I did this myself, it would be better to have someone else to watch as you pull. Just remember that with iron you have to pull beyond the point you want it to move to, don't get wild with it you could pull too far. Just pull and let down and then pull some more till you have 3 1/4" in front of the frame. I also put my insulated coveralls on the hood just in case the angle iron slipped off and came down on the hood.
There's no downside to the change. It works awesome. I don't know why Deere doesn't design it this way.
