Craftsman 21" Advanced Dethatching and Bagging Blade

[????Why can't reviews be formatted with paragraphs????]*****I bought this last year to try to boost the miserable performance of my "Craftsman Professional 190cc* Variable-Speed Rear-Wheel Drive Mower." Well, I'm not sure anything could help that mower produce really good results. This certainly didn't. *****The idea is neat - the stiff plastic strands 'rake' the lawn as you mow, sort of like a lite-duty power rake. However, the plastic tines fall out almost immediately. I cut a couple of swaths with good - I wouldn't say 'great' - results, then noticed lower performance for a few more passes, then checked. 2 out of 3 plastic tines on each side were missing. Same results after replacing them all twice. The replacement plastic tines can get expensive, too: each replacement pack costs about %25 as much as the blade originally.*****The problem is that nothing really holds the plastic pieces in - they just get bent in half and forced through holes in the blade, and come out just as easily. If I decide to use it this year, I'll try to rig up some way to keep the plastic wires in, then it might be worth it. Of course, the plastic parts wear out, too, so spending a lot of effort to keep them in just means re-doing that effort at each frequent replacement.*****In all, I suggest getting a metal-tined power rake attachment.
