One thing I want to bring up the second time...the right side is dead, not a thing wrong with the left side, works perfectly...first time that problem presented itself here, was when we installed a new knife, one section too short...seems to be the obvious here, but this time it is not...really burns when it only happens to the right side only. dmorgan@sit-co.net PS: we recently installed new rotor bars and Gorden's helical concaves...haven't been plugged one time this fall, use to be common practice here to go until the rotor slugged before we quit for the night.
