[Shop-talk] Mower PTO shaft

[John Innis]

Usually not possible.  THe vibration is often caused by one of two things.
Either a bearing at one end of the shaft has gone bad, or the shaft itself
has worn.  It could be the u-joint on the shaft, but usually it is the
sliding section that has worn to the point that it is wobbling.  I
recommend replacement.  This place:
http://www.the-mower-shop-inc.com/grasshopper_splined_shaft.aspx  has some
really nice splined shafts that might work,  DEFINITELY overkill, but they
will outlast the rest of your mower, guaranteed.  You will have to call
then to check shaft length, spline count, etc.
