My Dad's MX270 just experience engine failure at 1530 hours. Mechanic says that it looks as though the oil pump stopped working and the engine siezed. However, the dealer is being very mumm about whether other CaseIH tractors have experienced trouble such as this. I've been told that some CaseIH combines have experience such problems. Is there any basis to this? We bought the tractor at auction last year and haven't been able to confirm the year of manufacture to see if it is still covered by warranty--but the dealer says it is not. We want to confirm that some how. Anyone have some info/suggestions regarding this? Thanks.
