My 4110 is a 2004 model. No extended warranty and fourteen years later not a hint of a problem. I thought the reason why many purchased Deere equipment because it was built to last many trouble free years. I bought a used NH TC45 DA with an extended warrantee. Shortly after taking delivery the tilt / telescope steering wheel would not extend. The instrument panel fogged up with condensation making reading difficult.There was one additional problem that escapes me but I have warranty, .... right ? The dealer states they will repair the listed items at my expense only. The warranty only covers the drive train. Moving on to a NH TC 55 DA HSS , I did not buy any additional warranty due to limited coverage. Eleven years with no problems.
I have little belief in extended protection if the unit is operated properly and has proper maintenance. I never purchased one on a new motor vehicle for the same reason.
* Every two weeks without fail I get a call from a warranty company telling me our cars are out of factory service . For minimal cost they will replace five thousand dollar transmissions and six thousand dollar engines free of charge with this service. They do not understand blocked calls either.
