Sometimes in the middle of the night, you wake up and the lighting bolt strikes. This be the case regarding the breaking of PTO/Jack Sheave belts.
I knew there had to be a reason for the "extreme" tilting(angle)on the deck pulley.

Here is the culprit... The welded flange on the deck that holds the bracket...M136635 Arm that the jack sheave and pulleys support. This bracket is welded about 1/4" forward..to the front of the deck from where it should have been welded. This is causing the whole pulley assembly to run at a angle as shown in my other photos in another thread that I posted on Monday. Here is a photo of the...M78194 shaft with the worn areas (2) allowing these worn areas to wear much faster than normal.








To solve this mistake made by the JD factory, I will grind the bracket welds off, and position it in the proper location and re weld the bracket.

Is your tractor (and also) deck still under warranty? I would take this revelation to the JD Dealer and have them fix it (not saying you can't) to keep the warranties in place!

During all these repairs to the deck, I'm re-engineering some of John Deere mistakes. This be the case involving the infamous plastic bushings that JD installed in the #M136635 and #M111740 bracket arms. John Deere wants $1.95 ea for their bushings. Just returned from IBT.Inc. with four copper oiled bearing (in picture here) to replace the plastic ones at a cost of $.99 ea.

Makes a person think what JD is doing to their products to destroy customer relations.

Glad you said that FD611V, the last time I even hinted at the possibility they may be harming themselves the JD fan club were ready to tar and feather, cut out my tounge or shoot me, or cut it out then shoot my tounge ! :Stop:

I think with all of the info and pictures you have now... I would make one last trip to the dealer and talk to the owner. You have incontrivertible proof the deck was made wrong, and you made them aware of it during the warranty period.

If they won't advocate to Deere for you, I would go over their heads and talk to a regional manager.

it's very obviously a product problem, you've got all of your maintenance history, you should give it one last shot.

As a former business owner, if I saw all of your evidence and hard work, I'd be bending over backwards to make it right. I hope Deere does the same.

Now that you found the problem and most likely a defective deck from the beginning, would you still consider a belt driven deck in the future?

I ask because I have seen so many old JD's out there with original belts without an issue. I do not see the big benefit in a shaft driven deck. (Shaft driven rear tranny yes...)

Moondawg has a point, now you have proof that it's a factory mistake they should at least make good even if it is out of warranty FD611V !

And considering the money you have put out trying to keep a flawed deck running they may give you some help towards a new one, but if they are like most companies I doubt it but what have you got to lose ?

I still maintain that JD is just as bad as 99% of the companies out there where a design or manufacturing flaw is concerned DENY EVERYTHING. JMHO

Dito! if you can prove it was welded in the wrong place from the factory the dealer and deere should pony up a new deck or at least rebate you the dollars spent needlessly over the years.

I wonder how many other decks have the same issue. Could be the basis for a recall and repair of hundreds or thousands of decks!
