What It Is

This PTO (Power Take-Off) clutch pulley engages and disengages the mower blades on your riding lawn mower or zero-turn. It’s designed for Cub Cadet GT, RZT, SX, LX, XT1, XT2, ZT1, ZT2, and Ultima 46 series models, as well as other brands using the same 3-bolt pattern.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Works with 42”, 46”, 50”, and 54” decks, but measure your existing pulley diameter (typically 4”-5”) to confirm.
• Model number: Cross-references with OEM part numbers 917-05123, 917-05188, 717-05000, 917-05209, 917-05000, 917-05192, and 5219-164.
• Bolt pattern: This is a 3-bolt design. Check your original clutch for the same pattern and that the shaft diameter (usually 1” or 7/8”) matches.
  If your mower uses a different bolt pattern or shaft size, this won’t fit.

Key Things to Know

• Quality vs OEM: Aftermarket replacement at roughly half the OEM price. Some users report shorter lifespan than genuine Cub Cadet parts, but adequate for residential use.
• Installation difficulty: Moderate. You’ll need a puller tool to remove the old pulley and a torque wrench to tighten the center bolt (typically 40-50 ft-lbs).
• Common gotcha: The clutch may arrive with a slightly different wire harness connector. You might need to splice or adapt your existing connector.
• Warranty: Usually 1-year limited. Check the seller’s return policy before buying.

Should You Buy It

If you own a compatible Cub Cadet or similar-brand mower and need a budget-friendly PTO clutch replacement for home lawn care, this is a solid choice. Avoid it if you require OEM reliability for commercial use or if your deck has a non-standard bolt pattern.
