Your machine is the same as a 930545 but you have the seat upgrade on yours. If you go to the Hustler website at hustlerturf.com on the bottom of the page you'll see links to manuals. One the left side is owners and the right are parts. Scroll down to a 930545 or 931782 and you can download the books you need. On the parts you'll see in section 3 they call for a 601141 filter for your drive. These are self bleeding drives. When you pull the filter it will drain your system.
