Quick Answer
The Cub Cadet Pro Z 100 EFI 148, 154, and 160 commercial zero-turn mower families use the 917-05192 PTO clutch when matched to the complete model numbers shown below.
The mower-deck parts change by cutting width:
- Pro Z 148 with 48-inch deck: 954-05012A belt, 942-04417 blades, and 918-07417A spindles
- Pro Z 154 with 54-inch deck: 954-05013 belt, 942-04416 blades, and 918-07416A spindles
- Pro Z 160 with 60-inch deck: 954-05015 belt, 942-04415 blades, and 918-07386A spindles
This guide covers the confirmed Pro Z 100 EFI L and S model families. It should not be applied automatically to newer Pro Z 500, Pro Z 700, Pro Z 900, diesel, stand-on, or other commercial Cub Cadet model families.

Model Path Note
The confirmed Cub Cadet Pro Z 100 EFI 148, 154, and 160 L/S families use the same 717-05192 / 917-05192 electric PTO clutch path.
The important differences are the deck belt, blade length, and spindle assembly:
- 48-inch Pro Z 148: 954-05012A belt, 942-04417 blades, and 918-07417A spindles
- 54-inch Pro Z 154: 954-05013 belt, 942-04416 blades, and 918-07416A spindles
- 60-inch Pro Z 160: 954-05015 belt, 942-04415 blades, and 918-07386A spindles
The 48-, 54-, and 60-inch spindle assemblies are separate commercial spindle paths. They should not be mixed based on appearance or blade-center style alone.
The model-specific quick-reference diagrams do not assign a separate engine-to-deck PTO-belt number for these models. The listed deck drive belt provides the mower-deck drive path from the clutch through the deck pulley system.
The L and S versions use different operator-control systems, but the corresponding models with the same cutting width share the clutch and primary deck-maintenance numbers listed in this guide.
917-05192 PTO Clutch Specifications
- OEM Path: 717-05192 / 917-05192
- Warner Cross-Reference: 5219-158
- Crankshaft Bore: 1 inch
- Pulley Diameter: Approximately 6 inches
- Rotation: Counterclockwise when viewed from the pulley side
- Voltage: 12-volt DC
- Connector Style: Integral connector built into the clutch housing
The 917-05192 PTO clutch should not be confused with 917-05188, 917-05209, or 717P06468. Match the original clutch number, crankshaft bore, pulley diameter, connector, and anti-rotation arrangement before ordering.
