The rack/ram head is stuck in the forward position. The engine rpm's will decrease with the engine sounding like it is under strain. But it doesn't stall. Do the Belt slip? I don't believe so, I haven't had the side covers off while working. There is no squealing of belts. It takes 15 seconds or so
to clear the jam....I hit the on/off switch if it is any longer. I have had to do that twice with a knotty 14 inch Y Ash. Could be just a better clutch on the DR. I know their "Drive Train Pinion Gear" Is quite substantial and hardened twice if one believes the advertising. The Shaft one time and after the notches are cut, they are a 2d time. I would be more than happy, when I get engaged in splitting again, to try and jam the thing up with the covers off to see what is happening at that point. When I do, perhaps I can even catch it on Android Phone and up load it. We will see.
