Can it be done yes, as doorknob mentioned, they are ackward to handle, finger pinching sob, without removing feeder house your laying on your belly, plus you have the fun of removing bolts.Do yourself a favor, pull feeder house, not that hard of a job, forklift works best with side shift, a heavy skid steer with pallet forks will work, than your looking at it, keep in mind, you might need to have rotor in neutral, when you remove that amount of weight, rotor will turn NOW, normally I just get them lined up so I can get at bolts, torch might be required with rotor locked in gear, two people is much hander when removing, installing, Scott.
