Whew yes. This is much more likely to be a PTO issue, and probably nothing too awfully serious (though it could be a PITA). The engines in these things are all mounted "backwards" and the flywheel is closer to the seat than to the grille.

Heres a couple quick ones. I can try to take some better ones in the AM.

Alright then.

That's a bit confusing..... The rod that goes between the handle and the lever up front? The one with the adjusting clevis on it? If so, that makes a bit more sense.... but it isn't necessary to remove that. You may have to loosen it to get the belt off, but not remove it.

I agree, some pics of the PTO would be helpful. Unless you know what style of PTO you have. Need to know if it has the brake style on it like it should, or if that has been changed out. Lets start with that.

You can go here to see the differences between PTO's:
Your tractor should have "Type B with brake"

Something else to look for, is if the basket pulley (the big pulley on the front that the PTO fits into) has moved back into the engine. There is a bolt of the bracket for the starter/generator (s/g for short) that the pulley will usually hit when it moves back. Look there to see if it's moved.

Report back.


EDIT: I see you already posted pics. I'll post more shortly.

Do you have the PTO in the "OFF" position? If so, turn it on and try to start it. Some of the later 1X8/9 series had a safety switch on the PTO lever, so it may not let you do that. If you turn on the PTO and it doesn't even attempt to start, then you have that switch. If it does have the switch, then it gets more difficult.... If it does start with the PTO on, then it's likely your PTO clutch has failed. *IF* whoever did the engine swap did it right, it should still have a PTO with a brake on it, so it's possible that the brake is holding the engine from turning.

I'm thinking the PTO failed, or the basket pulley has moved on the shaft. Either one is going to require some mechanical ability. Would you like to proceed with diagnosing? Your going to have to go out and work on the tractor, and it's likely going to be a bit difficult if the PTO is bad. Do you have somewhere to work on it? I don't want to spend a bunch of time typing unless you plan to try and fix it. Not being mean, just matter of fact.

So I tried starting it with the PTO in the on position and it did nothing. With the PTO in the off position the starter is attempting to start the engine but is unable to turn it.

in picture #2 it looks like the starter/generator belt tensioning brace/bracket has dropped down and is trying to get into the belt groove.
Belt looks like it is being forced out and pivot point on the bracket looks like is has been grinding on the pto.???
Or the bracket is in there backwards??
Maybe.

There is a safety that keeps the starter from starting the engine with the PTO in the "On" position, so it sounds like that's working at least!

You are faster than me tonight.....

Your basket pulley has moved back. It is loose on the crankshaft.

You can see it hitting the bolt I talked about:

Go here and download the service manual for your tractor:

Find the section on the PTO. Follow instruction on how to remove it. Once removed, loosen the set screws on the basket pulley and pull it forward just a bit. You DO NOT have to remove the PTO bearing off the crank to do this. I suggest buying new set screws that are knurled on the end for the basket pulley. Check the key while you are there. The pulley should not be loose on the crank, or the key. (Loose enough to move, but not wore out.)

Hard to see at pic angle ,maybe gen bracket bolt loosened and is hitting pulley ?
Jon ,your on it !

Looks like the bolt that holds the sg bracket is loose. Tighten up the bolt, BTDT

Great! Thank you so much for the help. I'll get going on that tomorrow or over the weekend.
