I purchased the 140 H3 and model 41 mower deck last year.
I was looking at the drive belt and there was not enough tension on the belt. The original knob was missing so I purchased one and when I tried turning the new knob it will not budge toward the tightening position. The person who had the mower before me was using the jam nut to tighten the belt. The belt will tighten if you run the jam nut in against the mule drive case.
The stud is approx. 4 inches in length with fine thread on the clevis end and course thread on the knob end. I have asked a couple people and they said this is the correct stud.
I removed the mule drive to look it over. The stud & clevis look ok and the pivot pulley works ok.
I took the mule drive to my local John Deere dealer and the guy said it should work. He could not give me any tips as to why it would not work.
Has anyone had this problem before?
