Well, I squeezed the 88 today and am pleased with the results. <!-- s:twisted: --><img src="{SMILIES_PATH}/icon_twisted.gif" alt=":twisted:" title="Twisted Evil" /><!-- s:twisted: -->  Started out with 56 hp at pto speed and 63.5 at 750 pto rpm)2242 engine rpm.  I did 4 more pulls adjusting a few things and ended up with 67.5hp at pto speedand an even 70hp at 2242engine rpm.  My dissapointment came when I pulled down past rated pto speed to see when my torque curve went away and poweered right through the pto clutches, so i guess I am going to have to pull that apart and do a little fixin'. Does any one  know at what point the clutches just wont hold no matter how good they are set up?  I was told about 85 hp and that was on a gas tractor.
