We have the 9400 with the variable speed drive belt.  It has 2 variable speed shivers that can change diam. to control the cyl. speed.  It is not a 2 speed system where you take a pin in or out to change the cyl. speed. (I think that is how they work.)  It is the variable speed belt that ends up doing the slipping.  No, the belt is not that old. 

Anyway, if you have heard of anybody ever slugging this type of combine with damp ropy soybeans, I am sure nobody else have ever done this. 

How do you back the cyl. up to get the slug out? 

Does JD make a special bar or attachment so a person can back up the cyl.? 

JD does have some studs cast on the main cylinder pulley that you can get a long bar on, but you can not get a bar on very well as the studs are to short and other pulleys, ect. are in the way. 

It always seem the slug almost makes it through, but then it feeds into the beater and will not flow through the beater and there it sits. 

Yes, we open the cyl. wide open when we try and move the slug through. 

Better things to slip, I guess, than have things break.   

I guess it need a rotary as they don't slug.
