Hello guys,I am having a problem with my 4wd on my new holland 8560,When i press 4wd on the panel the 4wd symbol shows on the dash but still i have no 4wd,Would anyone know what the problem might be,I have looked through the manual but cant seem to find anything,Could it be the 4wd solenoid?Also i have checked all the fuses, does anyone know where the 4wd solenoid location is,Any help would be fantastic,Thanks guys
