One wrong part number means another trip to the dealer. These 21 pages exist to stop that, mapping nine assemblies to exploded-view diagrams: Blower Drive, Blower Components, Boot and Hose, both Gearbox variants (70050-04152 and 70050-94981), Driveline, Grass Bag and Frame, and the full Lid Components. Each diagram ties to a numbered parts list, so finding the Blower Housing (70050-94893) or Spring Lok Yoke Assembly (70050-93245) is a matter of seconds. Both gearboxes turn the fan at a 1.93:1 PTO ratio; lid seals spec out at 1/2 x 3/4 x 48 inches up front and 1/8 x 3/4 x 48 at the rear. Bookmarks drop you straight onto your assembly, so the number you order is the number that fits.

Once your number matches the right section, work from that exploded view to pull the internal component part numbers you need.
