From what I have been told by my dealer, KK is only providing one length shaft which usually requires trimming (he also said others are doing this) in a subcut application. I know for sure the shaft that came with the 60" KK (I borrowed my brother's) and my Woods tiller required trimming by about 3 or 4" (1.5 - 2" on each end). Just takes a vise and a hacksaw (I used my sawzall) and a few minutes.
