I hope you didn't the free manuals. because I got mine for John Deere Mower from reliable-store.com/ and I'm pretty much satisfied.
I think you will find a youtube video on this. I just checked there are a few..
Or just get that manual. I;m sure it will have the removal procedure.. it's no harm because if you are not satisfied they actually refund your money.
And please, this is no advertising, I;m literally sharing my personal experiences. If you want to get it from somewhere else, please please go ahead. Maybe that could be even better..
