I just bought a L3200 (172 hrs) from a friend the tractor has been sitting for about a year. It cranked with no issues and runs well. The only problem I am having is after filling the tank all they way up the gauge is stuck on 1/4 tank. Any ideas about what could be causing this?

Most fuel gauges can be tested by “grounding” the led. Clip a jumper onto the sending unit terminal and ground it to the frame to send that gauge to it’s full-deflection to test the meter movement. It that works, then look at the float (which may be fuel-logged) for movement. A coat-hangar bent into a hook and reaching inside the tank you might be able to move the float-arm if it’s sunk and/or stuck.
