I didn't even price a OEM regulator, I just found one on Amazon and ordered it, if I get 2 years out of this one, I will be very happy with that.
I'm curious how long my idler pulleys on the deck will last, I guess a lot of people complain and replace those often on various mowers, the Ariens mower I bought new in 2010 and have serviced for my mother ever since is going on 7 years old and it's all original spindles and pulleys. Battery and deck belts is all that mower needed.
My dads 445 JD which is 17 years old with over 1000 hours has all original spindles and pulleys.
Before researching when one on my Husqvarna failed I didn't think it was very common.
