Blades HU775L Replacement Blade? 5 Point Star 22"

Hi all,



I purchased an HU775L 22" Husqvarna self-propel second hand the PO had not performed regular MX on the machine. I've tuned up the motor, which runs great, but the blade is well dinged and I'd like to just replace it. However, I've been searching for two weeks and cannot find a replacement! I tried to sharpen, but my balancer is made for a circular bolt hole but this blade is keyed and doesn't sit on the balancer.



The mower's blade mount is a 5 point key and then a standard bolt holds it in place. The blade looks like a multi-purpose blade with a cutting edge on the leading side and several gnarly looking teeth on the trailing side.



I've tried searching for the part number stamped on the blade and nothing showed up. I tried cross referencing it to a different label and a Lowe's part number came up but it didn't have the keyed hole. Folks at Lowe's tried looking for one and couldn't find it.



I e-mailed Husqvarna five days ago but never got a reply. Anyone have a suggestion???



Thanks,

G
