How would that answer any of my questions?
Is the unit in warranty still? if so your dealer can take care of this easily.
The hour glass is always on, nothing wrong with that, but the lcd's burned out isn't good and your dealer can warranty it if its under warranty still.
Regardless, once a new hour meter is installed it will start from 0 again.
The part # for the hour meter kit is 367656
It's two years old, so probably not. I'm not sure what the warranty is on the mower. Thanks for the answers and the part number, I will check with my dealer.
