Tractor Stalls when going up or down hill but runs fine on level

I think I figured out what the problem is and want to share. Your weight shifts on the seat and the button that shuts off your motor does not have enough weight on it so your tractor quits running. I located the switch and put about
four 1/8 thick pieces of Velcro with sticky sides on it to make the plate where the switch hits keep in contact with the button. No more problem.
This was on a Kubota BX23S but I am sure it happens on other tractors. Oh by the way there are two switches one is gray the other is black. It is the black one that gives you the trouble.
Let me know if it works for you because I was like everyone else thinking it was the fuel.

Glad I saw this and will try it. I had the same thing happen and thought maybe my foot was just shifting and giving it too much HST.

I thought it could have been the seat because I felt myself shifting, but then I do stand while putting implements on the loader to get a better view and it doesn't stall then. I thought maybe the seat switch just kicks in when the HST peddle is depressed?

On a different forum site it was the carb bowl not filling due to a maladjusted float.
