ACEBRI Electric PTO Clutch Fit for TROY BILT for CUB CADET 917-05209 917-04552 917-05122 717-04552 Clutch for CUB CADET LT1050 LT1046 SLT1554 LTX1042 LTX1045, LTX1046, LTX1050, RZT50, RZT54 PTO Clutch

What It Is

The ACEBRI Electric PTO Clutch is an aftermarket replacement part for Troy-Bilt and Cub Cadet lawn tractors and zero-turn mowers. It engages and disengages the mower deck blades via an electromagnetic coil, designed for models using a 4-inch, 2-bolt pulley pattern.

Fitment & Compatibility

Before buying, verify your mower’s model number (not just series) against the listed OEM part numbers: 917-05209, 917-04552, 917-05122, and 717-04552. This clutch fits Cub Cadet LT1050, LT1046, SLT1554, LTX1042, LTX1045, LTX1046, LTX1050, RZT50, and RZT54—but only if they originally used those OEM numbers. Check your deck size (42–54 inches) is supported, but the primary fitment is the pulley diameter (4 inches) and bolt pattern (two bolts, 2.25 inches center-to-center). Measure your old clutch’s shaft diameter (typically 1 inch) and electrical connector type (two-wire flat plug). If your mower uses a different OEM number (e.g., 917-xxxxx not listed), this clutch likely won’t fit.

Key Things to Know

• Quality concerns: With only 2 reviews and 3.5 stars, consistency is unproven. Some users report premature bearing failure or coil burnout under heavy use.
• Installation difficulty: Moderate—requires removing the deck, disconnecting the wiring harness, and pulling the old clutch with a puller. You’ll need basic mechanical skills and a torque wrench (specs: 25–35 ft-lbs for the center bolt).
• Common gotcha: The wiring color codes may differ from OEM. Test with a multimeter before reassembly to avoid reversing polarity, which can blow the fuse.
• Warranty: Typically 1-year limited, but return shipping costs may apply. Verify with seller before purchase.

Should You Buy It

Buy this clutch if you need a budget-friendly replacement for a Cub Cadet or Troy-Bilt with the exact OEM numbers listed and are comfortable with a moderate DIY install. Skip it if you want proven reliability or have a high-use commercial mower—spend more on a genuine OEM clutch (like Electrolux/MTD) for longer life and better support.
