If it was a v660 I thing the sideknives would be hydrolic. Does the knife move in and outJust bought the combine and doesn't have it, has done rape in the past though as the side knife wiring is there. Doing our first ever harvest of rape this year (not too common round here) so need to get set up. Our other combine isn't set up for rape either but as we're only doing a small area, thought it would be best on this combine only.
