Rob, if you remove the shaft from either end, raise the tiller to full height and see if your shaft is a long way from bottoming, then it is too short. According to the TSC catalog, they have tiller shafts 28", 32" and 35" for $110 to $120, or they have an extension adapter for the pto shaft for $17.50. With the adapter you would have to Measure and cut your shaft to fit like a new shaft.
