anyone who owns a supersweet cab 2420 3040 4060 or whatever they're calling them today, make sure you check your air conditioner tension pulley. At 350 hours mind flew off and destroyed my plastic fan and damage the Finns of the radiator core as it bounced around inside thank God no leaks. In a way it's my own fault about two weeks ago while giving the tractor a once over checking belts and hoses I noticed play in the pulley, the dealer at the time seemed to think it was normal it ain't !!! Lucky for me my friendly dealer and I will split the bill. So go out there and give her a shake if it has a lot of play Ripper her out of there before she rips out your heart and wallet . Don't ask me why I'm laughing sometimes it's all you can do crazy things happen in life. I really can't complain in a little over a year I have put a lot of extreme heavy duty chores on this unit and she's never let me down no matter what I ask it to do even plowing the 50+ acres this spring while my case was down this is sort of a little hiccup, okay maybe a big hiccup but it could happen to any brand tractor . A picture of the new pulley it seems to have a rubber center around the bearing it must be for vibration, the rubber detaches and lets the pulley fly I wonder why it's not solid steel oh well just go out there keep your eye on it. Take care
