Couple of other things to consider. There is a straw spreader speed up kit available thru the productivity catalog. Also available is the curved bat spreaders. If memory serves you will need to have the straw_chaff spreader. I would go the curve bat route before speeding up the spreaders. Did thaton my 2188 and it works great with a 30' head. My machine had a beater, so am considering the vane from the chopper machine to equalize the spreader load.
