Hi my name is ***** ***** welcome to Just Answer. How are you? . The pulley you ate trying to remove is the one that drives the engine belt right ?

Yes. It drives the main drive belt to the transmission.

I used a 3 legged pulley puller, and all it did was bend the puller. I even hit it with a hammer while using a pry bar on it. It's not budging. I can see no set screws or the like. There is no room to sand it.

Is it possible to upload a picture of it. Also is there a bolt in the center of the crankshaft s
Ask Your Own Small Engine Question
Customer reply replied 1 year ago
The only bolt in the shaft held the PTO on. It was removed long before I tried changing the belt and pulley. I am a restorer of antique cars, and thus have access to lots of different tools. Also, I am no dummy when it comes to mechanics although my small engine / tractor experience is limited. I will try to upload a picture soon.
Technician: Briggs-Fan, Small Engine Technician replied 1 year ago
It should slide off you can screw the bolt in some and try using a 2 leg puller to free it up , you may need to use heat to but be careful because the crankshaftseal is right near that pulley

How could it possibly be so tight that a puller bent it, but heat could remove it? Th tractor manual states :slide the pulley dow to work the belt off..." Ain't no way,now how that one can "slide the pulley down"
Technician: Briggs-Fan, Small Engine Technician replied 1 year ago
A 2 leg puller may get it but heat expands and contracts metal so if it's seized it will free it up

Soak it with wd40, and put the bolt back in and try a 2 leg puller. It def slides down but is stuck from use

Please let me know if this is the same tactic after looking at the final pic.
Technician: Briggs-Fan, Small Engine Technician replied 1 year ago
Yes that's a keyed shaft , it slides down , that's what keeps it lined up

I bought a 5 ton 2 jaw puller for $30. All it did was further bend the pulley. No movement whatever. Used both PB and WD-40. This thing has cost me a small fortune so far.
Technician: Briggs-Fan, Small Engine Technician replied 1 year ago
The only other option it to try to cut it off but you run the risk of damaging the crankshaft. Have you used heat ?

A air hammer may help otherwise if you have a cutter wheel you can try to cut it along the key way

I heated it and caught the penetrating oil on fire. Had to run for the extinguisher. What a mess I now have. I did everything mentioned in the forum link you sent mentioned it's NFG! Beating it to death with an air chisel now, and it's still noy moving. Damn MTD and its engineers. Poor design!
Technician: Briggs-Fan, Small Engine Technician replied 1 year ago
I'm sorry the thing is giving you hell. I understand your fustration and anger . If you were local I'd come help you remove it . If you have a cutting wheel you can try cutting it but be careful and I'd cut the length of the keyway
