I have pulled a 16 row 22 inch old DMI stripper for the past three years for one of our customers.  it is on a staggered bar, I think 3 rows of units.  It worked good for what is was.  bean stubble only, no corn stalks.

He has now ordered a new 30 inch planter and will have me strip with my 30 inch Dawn units.  He has no time to strip in the fall and his stripper is pretty shelled out, so rather than buy a new 22 inch stripper for me to pull, he will just go to 30 inch rows.  If he did a 22 inch bar it would have been Redball.
