Made a movie of the WA500 loading lumps at the beginning, GOSH! another 3 inches lift would make a great bit of difference Greg.
The length of my loader arms are 9 inches, what's your's?
Near the end of the movie the loader is pushing up "fines", I thought those fatter tires would have floated better than the originals... not much difference though.
