I decided to look for some lawn mower forums and ended up here.
The Machine in question is a Craftsman Professional 21" self-propelled.
Model 12AE997E099
Bought it new 10 years ago.
I need some photos or good drawing of the belt installation. I've been burning up the internet and for some strange reason there is absolutely zip information on this thing.
I wanted to put on a new belt and finally got the old one off, but there is a spring on the lever that allows the variable pulley to open and close and it came off before I could see how it was attached.
I twisted wrenches over 50 years and I've never seen anything as hard to figure out as this drive belt set up.
Course the manual only says the mower must be returned to a dealer to get the belt changed.
Any links, help, etc. will be greatly appreciated. Been scratching my head on this thing for 2 days, too far from town to make a trip in to any mower shop.
Hmm, no similarity at all to mine. On mine everything is under the deck. Kawasaki powered too.
Those dragging rear wheels gave me some ideas to look at tomorrow, but I really need to see how the linkage for the belt and pulley assy at the engine shaft works.
Yeah, that's the machine. The lever, part 55, is what popped out on me.
A spring moves it down, away from the engine, then the control cable pulls against it to close the pullet halves.
The rear wheels lock up now like in that video link. If I can figure out why that's happening then maybe I can work back to the engine end and get that linkage correct.
Still can't figure out why there's zip info out there about this thing. Maybe this particular version was only made for a short period.
I doubt I'd have bought it if I had been aware at the time that the user had to take the thing to a dealer to get a friggen belt changed.
And where are those manuals the dealer shops would have needed?

Part number 56 is the spring you were talking about?
Yes, 56 is the spring. It's a fairly heavy coil with a curved tang on one end and a straight one at the other. That spring sat against a shoulder on the pin. #57.
It's fairly easy to see how things go together from the parts blow up except for how that spring is connected. The control cable hooks up at the point of that triangle shaped lever and pull against it.
After I had freed the belt from the transmission pulleys I was feeling in there trying to figure out what it took to get the belt free at that end. I could feel tension from that spring, but there wasn't all that much.
Suddenly that rod slipped out of the bracket, #58, that held it to the deck housing.
You'd think after 10 years of use there would be some wear marks from that spring, but nada.
Shoulda drained the gas and oil and laid the damn thing up side down, but who would have thought something like a simple V-belt could be so hard to get back in and then so impossible to find assembly information.
Would you believe it! I found the belt installation sequence in the manual for the Yardman version of that same mower.

And now I see why it just felt like the control arm just fell off. The torsion spring does not go on like I thought.
In a little while I'll go out and see if I can get that thing working again, for 10 years it's worked like a top.
Now why in blazes do some resellers insist their model be returned to a dealer for this simple job and the Yardman 979 manual gives complete instructions with a full series of excellent drawings? :thumbdown:
So, after I could see how that torsion spring went together on that control arm, putting it back together was a piece of cake.
Then I dropped out the entire real axle assembly to see what the guts inside that thing looked like.
Yow, what a stripped out groady mess! Pinion gear was OK. but the bevel gear, chain, and chain sprockets were a wreck. I found I can get the individual parts, but there's so much wear through out I might go with replacing the whole assembly. That'll be a little spendy so I got to think about it.
I'll put everything back together today or tomorrow and see if it will go back to running again.
That mower doesn't get used all that much now anyway.
My main machine to keep down a couple acres of grass and weeds around the house is a rig I put together with the tractor unit of my BCS 735 and a Troy-Bilt deck and engine unit I built a mount for that I can even get through the brome and thistle that's already waist high in places.
