I almost always have an implement on the back, usually the backblade or box blade, and make sure I have one of those on when doing heavy loader work. Even my rake does pretty well. Having the quick hitch helps even more since it pushes the weight farther back, effectively using leverage to increase the weight. Moving manure, mulch, or stacked hay just doesn't push the envelope as much as wet sand or wet dirt does. Getting a full bucket of that stuff can really squat the tires and make the back a little light if going down a decline.
