I have a 2003 New Holland TC45 gear drive with very low hours (<200). Everything was fine when I parked it last week. Now the clutch won't disengage. I can crank it, but I cannot get it into gear. The forward / reverse and gear selector levers don't grind but wont go into gear. The range lever grinds. I should say that any one of the levers will go into gear as long as at least one of the others is in neutral. They just won't all go into gear at the same time. Any ideas?
