Electric PTO Clutch Compatible with Troy-Bilt 2009 Mustang XP Cub Cadet RZT Series White ZT-42 ZT-50 ZT-5000 Replacement Part Number 717-04183 717-04622 917-04183 917-0462 5219-99

What It Is

This electric PTO clutch engages and disengages the mower blades on select Troy-Bilt, Cub Cadet, and White Outdoor zero-turn mowers. Designed for 2009 Mustang XP, RZT Series, and ZT-42/ZT-50/ZT-5000 models, it replaces OEM part numbers 717-04183, 717-04622, 917-04183, and 917-0462.

Fitment & Compatibility

Before buying, verify your mower’s model number (not just brand) and deck size. This clutch fits 42", 50", and 54" decks on the following:

• Troy-Bilt: 2009 Mustang XP (42" and 50" decks)
• Cub Cadet: RZT 42, RZT 50, RZT 54, and RZT 5000 series
• White Outdoor: ZT-42, ZT-50, and ZT-5000 models

Measure the clutch mounting bolt pattern (typically 4-bolt, 3.5" center-to-center) and shaft diameter (1" or 1-1/8"). Compare with your old clutch – if the pulley diameter or wiring connector differs, it won’t fit. This is an aftermarket replacement, not OEM Cub Cadet, so check that the two-wire plug matches your harness.

Key Things to Know

• Quality: Aftermarket unit with solid 4.8/5 rating (7 reviews). Most users report it works as well as OEM, but some note slightly louder engagement.
• Installation: Moderate difficulty. You’ll need a puller or bearing separator to remove the old clutch from the crankshaft. Torque the center bolt to 45-50 ft-lbs.
• Common Gotchas: The air gap may need adjustment (0.010"-0.015") if the clutch slips. Also, verify your battery is fully charged – low voltage can cause intermittent disengagement.
• Wiring: If your harness has a three-wire connector, you’ll need to splice or adapt. This unit uses a standard two-pin flat connector.

Should You Buy It

If you need a budget-friendly replacement for a worn or seized PTO clutch on a compatible Troy-Bilt, Cub Cadet, or White ZT mower, this is a solid pick. It’s not OEM, but the price is roughly half, and reviews show reliable performance for residential use. Avoid if you require exact OEM fit or have a non-listed model.
