Ok so took the mower to the dealer that I purchased it from. I guess there was a service bulletin on this mower because it keeps throwing the deck belt. The problem with the hour meter they said it just needs to be reset. Not sure how they do that but I hope that it is fixed when I get it back.
Please post what exactly was done to fix/repair that gas gauge/hour meter display, by the dealer. If they tell you that they only had to 'reset it' please inquire as to how exactly this was done, what was involved, etc.?
I have that same style fuel gauge/hour meter on my Hustler Raptor. After only a few months with my new Raptor the only problem that I did have with it was the fuel gauge needle indicator would constantly indicate "F" (FULL) regardless of how much fuel was actually in the tank. There obviously was a problem and when I called Hustler I was informed that they knew they had a problem with this and was told to take it to an authorized Hustler dealership service center and that it would be repaired free since my Hustler Raptor was under warranty.
I then asked if they could just send me a new fuel gauge/hour meter and or fuel tank internal sending unit and that I would replace it myself and they refused to do so. Hustler said that in order to replace just the fuel gauge/hour meter the whole fuel tank needed to be replaced and for legal issues only an authorized Hustler service center were permitted to do this type of repair.
I then called a couple of Hustler dealer authorized service centers and inquired specifically about this problem and was told that yes this was a known problem with this type of fuel gauge/hour meter and that it had to do with either 1.) the fuel tanks internal sending indicating unit going bad or 2.) the fuel gauge/hour meter receiving an incorrect voltage.
But as far as an unknown digit indicator such as what you posted a picture of ? well that is definitely a new one.
The fuel gauge/hour meters little hour glass indicator on the display is only an indication that the mower is keeping time (hours) usage.
