Grooming Mower Spindle Issue

[TN8Man]

I have a Titian Implement (now IronCraft) SGM grooming mower that needs a new spindle. I have the new spindle and in the process of removing the old one but I can't get the GUK SELF LOCKING NUT to budge that holds down the pully on the top side. I've sprayed some penetrating oil on it but it won't budge. Any suggestions on how to remove this nut?

Here is why it needs to be replaced. Stripped threads when the blade hit a tree root.

Put blade back on tight. Put a chain on end of blade to deck or frame. Put wrench on pulley nut. Hit wrench with hammer. Use a 4x4 block, or tie it to truck bumper and drive away. I have used all methods.

Have you tried an impact on it?

You could try and grind 2 flat spots on the stripped thread to be able to get a wrench or vice grips on there. Or maybe weld a nut on the end to get a ratchet on to hold against the other nut..

Just a couple of suggestions. Perhaps someone else here can also chime in with more.

Hope this helps!!

The threads are stripped so I can't put the blade back on. I do have a wrench securing the spindle from moving.

Not yet, I need to get a socket that fits first.

The shaft on the bottom does have two flat spots already and I have a large wrench holding it in place.

Definitely go with air tools. I went with air tools years ago after busting up my knuckles too many times, and dealing with extending wrenches with pipe etc...

The impact "shock" of air tools usually wins....

Yeah, I ended up with a big scrape/bruise on arm when the wrench slipped. I'll pickup the impact sockets tomorrow morning.
