We have been using Miller loaders for about 12 years now. Have yet to tear one up. Had the same one on a JD 4960MFWD for 10 years now. It has probably 6500 hours use with the loader. We would load 2000 tons of corn silage a winter with it. We have the 1.75 yard bucket with a grapple on it and you can easily get 2500 pounds of silage in it. I would also stack about 10,000 4x4x8 square bales of hay 2 at a time. We still have that tractor and loader and still move quite a bit of hay with it but use a telehandler now for most of the feed truck loading.
