I notice the power difference right away. The control for the loader valve seems to be a plus what little I've used the loader so far. The rocker foot pedal will take some getting used to over the heel and toe pedals. Hood and grill is all one piece, easier access to clean the radiator. New mount for loader, no bar to dent hood. Better placement of the left side controls. I always caught on the ones on the
B7510 when getting off. Drive over mower deck, not sure, many have told me not to do it. I don't like the location of the front remotes.
More to come as I have more seat time.
