With the 1460 combining tough beans tonight, the residue coming out the back seems to be heavy to the left side.  Is this just because they are tough? 

 Would the (double) straw chopper pulleys from a 1660 fit on a 1460? Would save me changing pulleys for  straw.

 What kind of progress would a 1680/88 with a 25' 1020 make in beans? Could  you get 8 acres an hour?  The best time I can make in beans was a rectangle 20 acre field done in 3 hours, I would like to get more acres in beans done quicker.

Thanks for any help, Dan
