Ok gentlemen,
New PTO belt. First outing since replacing. I think I finally got the deck belt corrected. It's on the 4th cut. But, sank in mud last week and smoked the PTO belt. Replaced, checked all pulleys on the deck and the bull. All seem free and not bent. Ideas?

Did the belt get wet or oily? Did the mower deck bottom out?
Either might cause slippage and overheating...

Thanks Harry.
No, this one did not. Deck did not bottom. I thought I had it. I was running the deck high and the belt tight. I saw with the new belt today, that the bull was contacting the chassis. Loosened the belt and lower the deck. This gave me clearance. But, same thing today and the belt had flipped. So, too loose I think. How much deflection should the PTO belt have? If you raise the deck, should the bull contact the chassis? I feel it shouldn't.
My last tractor, my fathers craftsman was bottom PTO. So the direction change is new to me.

No, the belt shouldn't be making contact with anything other than the pulleys. If it's rubbing on the top/front of the deck, it could be an indication that your deck is too high in the front and needs to be adjusted down.

Based on the belt number I can see in your photo (C44801), I assume you're running a later model RM-series deck on a 3000 series tractor, correct? If so, the deck leveling procedure is covered on page 12 of the Operator's Manual 8-56001

Page 11 of that same manual also shows how to tension the belt (should be a 3/8" gap between the idler pulley bolt & bracket).

Oh, by the way, if there are any site admins looking at this, I noticed that there is a typo in the Tech Library link to the above mentioned 8-56001 manual. It's missing the "c" and trying to link to "http://www.asecoltingersoll ...

Thank you for the information.

Finally got to work on it. This is what I was talking about. Got a new adjustment rod and belt. We're going for it today.

Ok. Here are some pictures. From what I can tell, all my measurements are in spec. I don't have a good level space to measure the blade level/pitch. The belt has a ton of deflection on the left side. I took a video, but not sure how to get uploaded.

Good evening all. I hope all is well in the community. Now that I had time to look. I think I'm on to something here, looking for some input. Should the bull/direction change pulleys run parallel with each other? I'm seeing a bit of canter towards center on the left/fixed pulley. The belt develops about 3/4 inch deflection on that same side, between deck and bull.

Thanks for bringing this up Ray, I'd missed the post. I think, it's fixed now. (correct me if I'm wrong,, it was in the operators section,,,)

Evening gentlemen.
Finally back to it. Busier than usual this month. So, pulled the bull down and have some questions, I hope you intelligent people can help me with. From my vantage point, pictures 1 & 4. The pulleys don't appear to track parallel. The line is exaggerated, but it appears off to me. Should they track parallel, as I believe they should?
Picture #2: I'm more interested in the bolt, not the slack adjuster. Should it be contacting the bracket?
Picture #3: this bolt as well as its sibling on the other side. The washer, now looks like a bellville washer and they are loose. Are they loose for pivoting or should be tight? Thanks again guys, this is very humbling, that I have not figured this out yet. I also, don't want to just shot gun parts at it.
