What It Is

This electric PTO clutch engages and disengages the mower blades on zero-turn mowers, specifically for Cub Cadet RZT Series and Troy-Bilt Mustang XP models from 2009, plus White ZT-42, ZT-50, and ZT-5000 variants. It replaces OEM part numbers 717-04183, 917-04183, 717-04622, 917-04622, and GT1A-MT09/5219-99.

Fitment & Compatibility

Check these before buying:

• Deck size: Works with 42”, 50”, and 54” decks on compatible models.
• Model year: Confirmed for 2009 Cub Cadet RZT and Troy-Bilt Mustang XP; earlier or later years may vary.
• OEM vs aftermarket: This is a direct replacement for OEM parts listed above, but not a genuine Cub Cadet part. Compare your old clutch’s bolt pattern and shaft diameter (typically 1” bore, 3-bolt pattern).
• Measure: Verify pulley diameter (approx. 4.5”) and electrical connector type (2-pin flat). If your original has a different connector, you may need to splice or adapt.

Key Things to Know

• Quality: Solid 4.6 rating from 11 reviews—users report reliable engagement and smooth operation, but some note it’s noisier than OEM.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, jack or ramps for access). Expect 30–60 minutes. Disconnect battery first.
• Common gotcha: Air gap adjustment is critical—set to 0.010–0.020” with a feeler gauge after mounting. Too tight or too loose causes slipping or drag.
• Wiring: Double-check polarity; reversing leads can blow the internal coil. Match wire colors to your harness.

Should You Buy It

If you own a 2009 Cub Cadet RZT or Troy-Bilt Mustang XP and need a budget-friendly replacement that fits and works, this is a solid choice. It’s not OEM, but it matches specs and has good user feedback. Skip it if you want a genuine Cub Cadet part or need an exact noise match—aftermarket clutches can be slightly louder.
