Whether you are rebuilding your John Deere riding mower or you were in an accident and bent the driver belt pulley, you will have to remove the driver belt pulley to get a new pulley on so that you can get back to mowing. The drive belt pulley is the main drive pulley that is the start of all major functions with the mower. This pulley is bolted onto the base of the crankshaft under the engine.
