PTO Clutch & Wire Harness Replacement for Warner 5219-177 5219-171 5219171 5219177 for Exmark 127-3410 for Ariens 00480600 for Cub Cadet 717-05000 Electric Lawn Mower Clutch

What It Is

This is an aftermarket electric PTO (power take-off) clutch assembly with a pre-attached wire harness, designed to engage and disengage the mower deck blades on zero-turn and riding lawn mowers. It replaces OEM numbers Warner 5219-177, 5219-171, Exmark 127-3410, Ariens 00480600, and Cub Cadet 717-05000.

Fitment & Compatibility

• Measure first: Verify your original clutch’s outer diameter (typically 4.5 inches) and shaft diameter (1 inch or 20mm). This clutch fits common 4.5-inch Warner-style units.
• Check bolt pattern: This uses a 3-bolt mounting pattern. Confirm your mower’s mounting holes match (center-to-center spacing ~4.25 inches).
• Confirm wire connector: The included harness uses a standard 2-pin flat connector. Ensure your mower’s wiring matches—if you have a different connector, you may need to splice or adapt.
• Known fit: Works on Exmark Quest, Ariens Ikon/Zenith, Cub Cadet Z-Force/ZT series, and many other models using Warner-style clutches. Always cross-reference your OEM part number.
• Voltage: 12V DC system only.

Key Things to Know

• No shimming needed: This clutch comes pre-gapped and assembled. Just bolt on, plug in, and test engagement.
• Installation difficulty: Moderate. You’ll need basic hand tools (wrenches, screwdriver) and may need to remove the deck or belt guard. Allow 1–2 hours.
• Common gotcha: The air gap (0.012–0.020 inch) is factory-set. If the clutch slips or doesn’t engage, check the gap with a feeler gauge before returning.
• Quality note: This is an aftermarket replacement, not OEM Warner. Build quality is generally good, but the wire harness may be slightly shorter than OEM—route carefully to avoid pinching.

Should You Buy It

If you have a confirmed compatible model and need a budget-friendly replacement for a worn or failed PTO clutch, this is a solid choice—especially given the perfect rating. It’s ideal for DIYers comfortable with basic electrical and mechanical work. For commercial/heavy-duty use, consider an OEM Warner unit for potentially longer lifespan.
