I post before this answer in a lot of forums. looks like the combines don't make a lot of hours in America. Here are my numbers... My '82 Deutz M2680 - is now 13000 hours, and still working. Notice we only cut 300 hours a year in the last 5 years. Neighbor '84 Deutz 1600 - He traded this machine two years ago at 15000 hours but she's still combining. Neighbor '88 John Deere 1074 - 10000 hours on the clock. Here in catalunya (spain) the combines ase usually changed at 10000-12000 hours.
