Yea, that is the record, but the 1250 is one gutsy tractor.  Had a neighbor who built a fairly large and deep pond behind his house with one.  Don't know the exact size but he had enough dirt to put a couple of feet over at least 3 acres.  He did it  with the loader and a box blade.  Took him a couple of years and by the time he was finished the tires on that thing were slick.  Sad part is his wife kicked him out the house about the time he got it done.
