123 won't budge
 

After rebuilding my PTO and carb, my 123 sounds great and my blades spin perfectly. I got the carb rebuilt (ty Alvy) a few days ago and mowed a little, but was leaving ruts with all the rain we've been getting. So I was satisfied and put the 123 in the barn.

I just went out to do some mowing, but she won't move at all. She fires right up and sounds good, but nothing engages when I push my stick F or R. Not even trying to move. I don't even know where to start. Any advice?

My first thought is that a pin broke in the driveshaft, I'd remove the deck and crawl under to take a look.

Before removing the deck, can you shine a light from the back of the machine and see the back of the hydro pump to verify the hydro is spinning with the engine running (parking brake on)? I'm not familiar with narrow frames enough to know if it's possible. If it's not spinning engine speed you have a broke pin like Tim suggested.

Or look thru the screen at backside of engine.
While turning engine over to see if driveshaft turns with engine at engine end.
There is another pin at the other end of driveshaft with a rag joint then another pin.

Seems like the pin in shaft at engine is the one that breaks first.

If it is the engine end pin, you need to fix the coupler on the engine that pin rides in.
The pin slot becomes "L" shaped.
You can fill weld the worn portion of slot and grind it back to what it looked like new.

OK, so this must be my culprit

Any chance I can just slide a new pin in?

I would fix that coupler first. You can just push a pin in if you want. Probably will fall out again though cause it fell out once it will do it again. Jeff in PA has solutions for your problems.

Yup that'll do it every time.

A 1/4" bolt and lock nut will get you by until parts come if you need to use the tractor.

Diagnosed and repaired without setting eyes on it 007! I have no experience welding, so should I try to find a replacement?

Terry, does Jeff have a website?

Olds, I saw a few pics of people using bolts on theirs. Any reason a high quality bolt and locknut wouldn't be a permanent replacement?

or this one with driveshaft from one of this websites sponsers. But I think it is made of platinum.
