"You could do some serious damage on other things besides stumps with that tool!"
Yes, like your bucket cylinders. If tilting in the ground to dig up stumps, let the hydraulics do the work. If the bucket cylinders are extended and you drive forward with too much pressure on the bucket cylinders they could bend or worse, break. The same way they do when rookies in skid steers tilt the bucket down, lift the front wheels a foot off the ground and drive full speed ahead trying to dig up hard packed ice and snow. That stump bucket would add an awful lot of leverage to bend the cylinders.
