A few years back i had a new bolt on cutting edge installed on my wheel loader. They cut the bottom of the bucket out where the edge should be about 12" deep and welded in a new piece of that hardened steel for cutting edges, then drilled holes for the bolt on cutting edge. I'm only 30 but i'll probably be dead and buried before i wear that out. That cost me $1500.00 for the whole thing.
$230.00 actually sounds reasonable for a dealer price.
