1. Removed mower deck out from under tractor
2. Attempted to remove the machine screws for the pulley guards, however they broke off due to being seized to the deck. Drilled out and replaced with similar size.
3. Removed top mandrel nut, removed the worn belt pulley.
4. Loosened the 3 machine screws to mandrel, and separated from deck.
5. Removed blade bolt to detach blade. Leave blade secured to mandrel as you will need it for leverage to loosen the nut above belt pulley in order to effectively remove pulley.
Reassemble in reverse order with all appropriate new parts.
