I have a question on the guards on a sickle bar in general.... I had a shop manual for an older haybine. It said when adjusting the knife to cut you could bend the guards up in order to make the sickle contact the guard. Well I tried this slipped a pipe over the pointy ends of the guard I sure as hell couldn't bend them Does anyone do this? Seems the guards now will break off before they would bend. On a combine head they have clips that fit in behind the knife itself to hold the whole knife forward and down I just haven't found a good way to adjust the ones on the haybine
