Just acquired this tractor. Came with a dozer bucket and a blade on the 3 pt. Am operating a hops farm. Wanted to grade my road to the farm. Have a 3 mile drive way. Does this tractor have a "float" for the 3pt hitch? All I seem to be able to do is dig. Can't seem to keep the blade at a constant height. Any help would be AWESOME! The salesman told me there was a float, if there is I can't seem to figure it out.
