[AJD] Two Cylinder JD's and Power Driven Equipment

[Duane Ledford]

Thought I would ask you folks what your opinion and knowledge is about this.  Have 
ran across several individuals who claim that if you use any type of PTO driven or 
belt driven equipment on a two cylinder JD, that the bearings of the equipment will 
be ruined.  Their reasoning is that the uneven firing of the two cylinder engine 
pounds on the bearings, universal joints, etc.  I might be able to see this if you 
were lugging the tractor for an extended time.  But if this is true, wouldnt every 
bearing in the tractor be subject to this pounding, therefore need frequent 
replacing?  Bearings wear out, but I really haven't seen any more frequency in JD's 
bearings needing replaced over any other brand.  Has anyone done or heard of a 
study of this "rural myth?"  Would be interesting to see measured results of the 
differences in stress on equipment between the pulsing  two cylinder engines over 
the smoother running four and six cylinder ones.  What has been your experience? 
What do you think?
