Nice feature. My 2012 MX4700 does not have that feature. I hand-pump out of a 30 gallon diesel caddy, and my indication that the tank is full is when diesel spills out all over the concrete floor.
Kubota Grand L Series have that "beep" feature. Mine is a 2008 model and I find it very usefull since I have a manual pump and I can't easily keep an eye on the tractor fuel thank.
yeah, that's good top know. when i first got this tractor and had to fill up on the job sight with cans id have to try and look in when filling and listen for when it was almost full. the beeper would have been nice to know about then
