I have a 2001 claas RU450 for sale. Header came with our chopper, we used it on 100 acres last year. One gearbox seal seeps oil. I have the missing crop lifter and RH side shield just havent bolted it back on yet. Only reason were selling is we found a newer RU450 extra we couldnt pass up. Head was on a 491 claas Jaguar.
