Took mine off my 8200 mfd and do not miss them a bit.  Many of those have been take off here.  Bought my tractor used with them on.  After a few years I was thinking maybe I don't need those with my machinery size.  The hardest thing I pull is a 5 shank ripper in the fall on about 25 acres and a 13 shank Case 5310 applicator.  I run out of power before I do traction any day.
