Any holes in or thru the pulley top to bottom? On my Ingersoll the outboard pulleys had holes. Used couple long carriage bolts and a steering wheel puller. Used a die grinder and 1/4" burr to make the holes oblong, clipped the sides of the bolt heads (opposite sides) so I could roll them in, stand the bolt up and turn 1/4 quarter turn.
Or you might be able to press the spindle shaft to the key and use a bearing splitter. Tom

there is no holes in the top for a puller.the pulley is some kind of plastic so heat is out of the question.the shaft is bent but the pulley is good i just need to get it off to replace the spindle

i have no idea of how this comes apart without getting the pulley off first.the nuts are on the bottom and the bolts are under the pulley so i can t get a wrench under the pulley to hold the heads

You need a true pulley puller or you need to make one. A simple 2 piece U shaped piece of flat plate works well. Cut a U in each piece just wide enough to slide in and under the pulley then bolt them together and use that as the part you use the puller on. I did that to pull the press fit pulley on the Farmall A/B engines

That looks like a golden oldie. I am not familiar with that spindle, but here are some idea.

Idea #1: Does it look like the blade adapter is a separate piece from the shaft? If so, you might be able to pull it off with a puller using a bolt in the shaft, then press the shaft and pulley out of the housing together.

Idea #2: Does it look like there is a woodruff key still in the pulley? You may be able to press the shaft down through pulley and housing until the key hits the top bearing, then press the shaft and pulley back up, shim between the pulley and bearing, then press down again until you can get the woodruff key out from between the pulley and the top bearing. then the shaft should come out the bottom.

Both these ideas assume the shaft is straight and has no shoulder on it.

Penetrating oil would be a good idea. Heat would be a good idea too, but that pulley looks like aluminum so use a propane torch, not acetyine. Be aware that penetrating oil does burn, if you use both.
