I have one on my L2501, works great as long as there isn't too much snow. I've used mine for about 8 years. I have a third function for angle, but on the farthest angles the blade does not sit flush. I really like how I can push the snow into big piles, as I don't have a bunch of room to put it.
I have a paved driveway so it's nice to lift the front end, put the weight on the blade, cleans the snow perfectly.
Mine has the composite/rubber blade, on each end they are wore down some, it can be flipped, once its wore too much, not sure when I'll do that. Seems to be lasting a good long time. Mine is the 72" land pride snow trip blade.
I have hit a few unmovable objects, and the blade just tilts, and will just lift the front end, definitely not going fast enough to break anything, I guess if you were in high and rammed something you could, I am usually in low.
