-Check the locking bolt that hold the tine shaft to the main shaft. Possibly it's broken. If so replace new bolt. you should be good to go again.

The Craftsman part number 66054 corresponds to a link arm, but without specific details or access to Craftsman's database, it's challenging to provide the exact length of this part. To find the precise length of the link arm with part number 66054, I recommend checking the product description or reaching out to Craftsman directly through their customer support or website. They should be able to provide you with the accurate information you need.
Hi Joe
Still having trouble with that old mower! I thought you fixed it? You stated
the reason it was turning over and lock up the mower had the wrong starter on it the Starter Motor Drive Bendix had 16 teeth and the mower needed a Starter with 14 teeth so I changed the Starter out. That's what I did.
I reckon you are using batteries that are wearing out and don't have the required amps. Jump start the mower using your Santa Fe with the engine running. Or take the batteries to an Interstate Battery shop and ask them to test them. That is free, but they can also pulse charge them to desulphate the plates. There is a small charge for that and they keep the battery for 24 hours.
Other things you can try.
Remove the starter and connect it direct to the battery. See if it spins freely?
Turn the engine over by hand to see if there is stiffness. Then do it with the plugs out.
