Quick Answer
The Cub Cadet RZT-S54 KW 54-inch zero-turn mower uses the 917-05209 electric PTO clutch path when matched to model number 17AICBDA010. The matching 54-inch deck parts path uses the 954-04329A deck belt, 942-05056A blades, and 918-06978 spindle assemblies.
This is a controlled RZT-S54 KW path. Do not merge it with older or alternate RZT-L54 / RZT-S54 54-inch deck kits that use the 918-05137 / 618-05137 spindle and 942-0677 / 742-0677 blade path.

Deck Kit Option
For the full 54-inch RZT-S54 KW deck rebuild path, use the 54-Inch Deck Rebuild Kit for Cub Cadet RZT-S54 KW. This kit includes the 954-04329A deck belt, 942-05056A blades, and 918-06978 spindle assemblies for this model path.
Deck Path Split Note
Several Cub Cadet RZT 54-inch decks share the 954-04329 / 954-04329A belt family, but they do not all use the same blades or spindle assemblies. The RZT-S54 KW path in this guide uses 918-06978 spindles and 942-05056A blades.
Do not use the RZT-S54 KW deck kit if your original deck uses the 918-05137 / 618-05137 spindle and 942-0677 / 742-0677 blade path. That is a separate 54-inch deck kit path: 54-Inch Deck Rebuild Kit for Cub Cadet RZT-L54 KH, RZT-S54 & Mustang 54 XP.
