The feeder house and rocktrap, if equipped, must come off. The rear drive is a splined shaft and simply slides off. A loader or forklift make the job much easier. I have a speciality rotor for a 40 or 60 series combine. bkhall@nwiis.com
south alabama , $1200 standard rotor is well balanced and does not vibrate, will take a day to get it out.it has 3200hrs on it, rasps look good, may need rear wear bars but will work fine like it is. can truck ship to you IJ
