MTD 17210-Z4M-821 OEM ELEMENT-AIR CLEANE

I was buying Scags blades but they kept on breaking! I don't mow fairways ;-)
These seem to work very well and you can't beat the price. No they aren't Marbain but like I said my Marbain blades kept breaking. I haven't had breakage with these. They do sound different but work as well. Maybe they have a different angle on the lift? I really don't know.They do the job and I'm buying my second set as we "speak". They are mower blades and work well as such. There really isn't much else to say.
