Thanks for the help, I will try that link.. I'm pretty sure I bought this mower from a now closed lawn mower shop. So not sure why it wouldn't be a US mower.
I tried asking the mower shop but they couldn't or wouldn't help me.
The model is HRX2172HXA
Series number MAGA-1591849
Thanks for any assistance on this matter. I was just curious when I bought it. Its the oldest hrx I have and runs as well as my newest one.
