I was the one that said normal digging.
And by that I ment your average homeowner type stuff. Like cutting in a flower bed. OR leveling a small area for a propane tank. OR skimming some high spots in the yard to fill in low spots.
I would consider things like digging an ornamental pond, cutting a driveway, digging a ditch, and things of the like to be of heavier tasks.
But if the only action the loader is going to see is things like scooping manuer, hauling loose material, and moving snow, the STD bucket is fine and has more volume. BUT if you pan on some heavy digging, prying out stumps, etc, by all means get the HD bucket.
