I need the owners manual for a Craftsman 625 series 22 inch blade rear bag mower with Model# 50853011-0

I'd just take it to a small engine guy and pay the $. They know all the tricks and it will save you a lot of grief.

Check if your belt on. The manual states taking you front wheels apart. Remove grass wrapped around parts. Grass to high. Raise platform up.

Tecumseh engines usually recommend SAE 30 oil. Briggs engines allow 5W 30 or 10W 30.

Is battery powered, did you try calling sears tech center for further info ?
i have found them to be very helpfull with mower problems.

see if the blade is bent the check the key under the flywheel

does not sound good the off balance of a loose blade could have caused the rod to break inside the engine the age of mower and how much use it has had could be a factor only way to really know it to look inside the crankcase.

there is different blades do you have the right blade for bagging?

Check under your mower and see if the blade sheild has bent in towards the blade. This could be your problem. If so take a hammer and tap the sheild back in place. GOOD LUCK.

Contact Sears as they sell Craftsman exclusively. I am sure they can help you out.

I have the same mower, the gap, according to the product specs. is .030 inches.
