I'm cleaning up some dead pickers I have sitting out back. The 313 and 326 huskers will donate rollers and other rebuilable parts to a shop in PA as cores. The 311 and 324 gathering units can be combined together to make one good unit, and I'm contemplating doing this and installing a 314 sheller. My question is, does the 314 need the HD 4-joint powershaft on the gathering unit or will the 3-joint that I have do it?
