Don't know about Kuhn.  We have a 195 that's hauled a lot of crap. Be sure the walking axles get greased.  If not, the mountings may break loose from the frame and axle will tip enough to snag the apron.  We're on our third apron, second top beater, second set of main beater combs, and soon to be second slop gate.  Box lasts forever.  Sounds like a lot of repairs, but its hauled more crap than I care to remember.
