Toro blade cross reference 108-9764

[jwales]

So I have a newer toro mower with a ruff blade (131-4547)and I think to ruff to re sharpen. I happen to have an older spare toro blade (108-9764) that I was going to replace with until I saw the number difference. They are both the same length, design is the same, weight appears to be similar. Can any one tell me if these are interchangeable or where I can look to make that determination. Curious if toro just changes numbers every so many years?

Thanks

Bolt it on and go. They probably changed suppliers.

Same blade basically. The 131-4547-03 replaces 104-8697-03, 108-9764-02P, 108-9764-03.
