lol. My “lightly used” Land Pride RCR1860 had the stump jumper crack all around the pivot point for the blades. My good friend has done much welding on it over the years. It’s on its second gear box, second set of skids, second tail wheel frame, third tail wheel, third set of blades (maybe fourth?).
Mine doesn’t have a ridge in the deck from the blades hitting the deck, but I do believe the blades can flex a fair bit under heavy use (some might say abuse?). Or the T bar under the stump jumper may have a bit of aftermarket ground contact induced adjustment. Keeps the upper edge tips of the blades sharp I suppose
