So just a little update on this. I ended up getting out the grinding/cutting wheel on my RotoZip and took some advice from this thread and leveled out the pin down to the link. I didn't go crazy but did go down a little deeper then just flush. After that I beat the snot out of it and said many 4 letter words (had to ask the kids to go inside). Finally it came out!!!
Thank you all for the advice
Also, just a note for you that might be interested in getting one of these.

This hammer adapter does fit just fine and can be used to push out pins. Sadly the air hammer I bought just is not powerful enough to knock out pins
I tried to use this setup to knock out the pin on my 73's clutch and the pin just sat their and laughed at me and my little hammer
So I got my can of PB Blaster, mini sledge and roll pin punch and moved my snot beating over to this tractor HAHAHA! I won and the pin lost this time around without much argument.
I was hoping to put a creeper on this 73 but I just can't see how to get that pin out of the link that attaches the drive shaft to the trans-axle. I don't have access to a full shop and those type of lift tools so getting the access to this area of the tractor is just very hard. I'm guessing this is why some folks drill a hole on the top of the frame to see the pin area. This tractor is not going to stay stock so maybe I'll do that next. Right now I just want it to run and with that pin out I can at least replace and repair the plates and disc. I really do like the simplicity of NF tractors but not having the tunnel cover like on the WF tractor's is a bugger
Like I said before, thank you all very much for your advice and help with this!
