Sickle bar operation

[JayB 5]

I have a side mount sickle bar on a 1277 tractor.  When I first used it I fit a hidden steel post that stopped the thing dead.  Not long after the shaft broke in the wobble box. I have since had that welded and also bought a second unit. So I now have two sickle bars.  My question is this.  When I get this back into operation is there a need to control the speed of the cutting bar?  if so, how is this accomplished as the drive is off the engine.  I am hoping that speed was not a part of the original failure.  Any suggestion?

Well hitting a object that stopped it dead did not do it any good, could have broke a number of things. As far as the speed you have to reduce RPM, you must find a RPM that is high enough to keep your motor cool and lube splashing around and yet slower than the normally  govern 3600. Those sickles were never suppose to run at that kind of RPM. 3600 is just to high for the wobble box
