There is very likely a setscrew (sometimes 2) holding it, be sure to remove it (them) completely, then, scrape or sand off all the rust you can get access to from the pulley to the end of the shaft*. (Once you get it moving, there is no point in dragging it over still more rust to get it off). Add penetrating oil down the set screw hole(s) and on both sides of the pulley. Resist the temptation to pry against the engine sump with a gooseneck bar to get it loose, you will probably bust a hole in the cast aluminum sump first. When you tighten the wheel puller, tap on the pulley while it is in tension from the puller (often helps break it loose). If it starts to move, add more penetrating oil (it will now penetrate better). If it starts to become too much of a job, like one of the others said, you can cut the pulley and replace. If you can't get at it with a repricating saw. Try drilling a line of overlapping holes from the shaft to the edge, split and spread it preferably with bolt cutters, or by driving a chisel or large screwdriver into the slot. Go easy on the pounding so you don't crack the crank case. It is just cast aluminum and won't take a lot of abuse. *If there is a step down in the shaft dia, you only need to clean it up to that point.<a href="http://www.jewelrymakingidea.com/jewelry-making-technique.htm"> Flying Dragon</a> I am presuming the pulley is on the underside of a rotary lawnmower.

You spray the whole thing down that tap it over and over. Repeat the process a few times and let the fluid soak in. Then id try a hub puller, it's a claw type puller, POSI-LOCK is a brand i've used(google it) it's strong, the pulley will give before the puller does!<a href="http://www.ecohomefashion.com/furniture-73"> Greg M</a> a product called “Aerokroil” (google it) works great for loosening up rusted and seized parts.
