Here is a way to do it.
Reinstall the center bolt most of the way in.
Install a old blade or heavier bar stock with matching blade mounting pattern leaving the bolts loose enough to get a two jaw under the edges of the blade. There are other type of pullers that you can mount directly in place of the two blade bolts. I have one here that works with my bearing separator that could be used.
Now apply pressure via the center jacking bolt of the puller until hub breaks free. You may a longer center bolt if the hub is really seized (and yours does appear quite rusty) to the crankshaft as provide more jacking room. You do want the center hub bolt threaded in most of the way as to prevent damage to the threading. In extreme cases you may even need some heating.
