I need to know how to remove the drive pulley from a 25hp Briggs on a tractor supply rider. It is a pretty thin metal pully and don't think any puller I have will pull it without bending it. Any help will be much appreciated.

On most of the new tractors the pulley will come off pretty easy once you remove the retaining bolt in the bottom of the crankshaft. Make sure both drive belts are off of the pulley particularly the top one as the pulley can hang on it. If it's rusted to the crankshaft tapping it with a hammer or air chisel will sometimes do the trick. If it's really stuck on there and you need to get it off, you will need to purchase a new one because you will most likely destroy the old one before you ever get it off.

I'm trying to pull a pully off also but from the transmission. the pully isn't held on by a retaining bolt it is some kind of bolt but the head is round. how do i remove the bolt?
