Hi! I am working on a side mount sickle bar mower for two-wheels. I work on the drive system (very special) No pitman. All position sickle bar 45deg down and 90 deg up. I reduce 965 rpm speed to 640 by pulleys. Run very well empty. But Yesterday for first time I connect the moving cutting bar. The mower shakes a lot. Too much! I think I must balance the moving parts (Bar with knives) with my drive system. I plan add counter weight. I send pictures soon. Oldmech
