Just curious if anyone else has had this issue with their 3rd Function Valve. When pressing the 3rd Function switch while the grapple is closed or with out the grapple hooked up, the valve or something is makes a loud clunking noise. Don't recall this happening before installing the grapple. Otherwise the grapple works fine.

Any other issues with your tractor?

I don't have a 3rd function valve, but it could just be a solenoid actuator snapping open and closed when you hit you the switch and perfectly normal.
