how to remove engine pulley on Toro LX500

Could someone please explain how to remove the engine pulley on a Toro LX 500 Lawn Tractor. I have tried to remove the pulley with a 2 arm puller to no avail as the pulley will bend if I use this method. I want to slide the pulley down the shaft in order to remove the transmission drive belt.

I feel your pain.
Unfortunately, pulley removal on these units is not an easy task and typically results in destruction of this pulley.
Fortunately there is an alternative that will allow you to keep the pulley.
The alternative consists of raising the engine assembly up enough for the pulley groove to rise ABOVE the frame and then work the old belt off the pulley and snake it back down through the pulley opening in the frame.
Then you work the new belt up through the hole and onto the pulley.
Then lower the engine back in place.
Been there, done that...........sounds worse than it is.
You will of course need to remove the exhaust header pipe bolts/nuts from the cylinder heads if you can't raise the muffler assembly along with the engine, so study your configuration carefully and if it looks like the pipes need to be loosened from the heads, be sure to have new exhaust flange gaskets ahead of time.
The only sure way I have found for removing the pulleys can only be done with the engine removed completely so I can assemble a 2 piece plate type T-bar puller behind the pulley.

Thank you for the info, I jacked up the engine and was able to remove the belt. Once again thank you.
