I have a 1955 620 which at some point had three pt hitch, hydraulics etc added. Under gas tank it has a fuel shut off valve that is operated with a large flat blade screwdriver.
My question(s): is this original equipment?
Should I shut this off when not using tractor or the valve on the sediment screen?
The guy I bought it from was shutting off the valve under the tank with a scredriver. Somewhat difficult (and you need a screwdriver).
