Auger motor fan blade

[boomer405]

Sorry if this is dumb question but i couldnt find anything on google. I need to replace my auger motor fan blade due to one being broke, so i got a new fan blade in but when i was trying to remove the old one seems like its stuck. Tried to pull on it but didnt want to break it off, just curious if there was a special way i need to remove it or just pull a little harder on the old blade. Thank you

How is it secured to the motor? On some fridges they add glue to the shaft crazy seems to me
