Your RC72-29A parts catalog runs 30 pages and maps every assembly: universal joint, bevel gear box, pulley holders, blade and side pulleys, tension pulleys, mower deck, front and rear wheels, roller, discharge deflector, lift linkage, mower link stay, lift arm, and clutch damper. Each section pairs an exploded view with a numbered parts list, so you can pinpoint a component before ordering it. The numbered callouts tie straight to the part list, so a worn bevel gear or a stripped pulley boss shows up as one exact line item. Interchangeability and serial number data sit with every assembly, and a country code cross-reference table up front confirms which part numbers fit your machine configuration. Bookmarked by assembly and keyword-searchable, it opens on any device when you need a number fast.
