8TEN Gen 3 Electric PTO Clutch for Warner Cub Cadet MTD Ariens Gravely 5218-6 5218-94 717-3403 917-3403 09232700

What It Is

This is an aftermarket electric PTO (power take-off) clutch for riding mowers and zero-turn mowers, specifically designed to engage and disengage the mower deck blades. It’s a direct replacement for OEM clutches on Cub Cadet, MTD, Ariens, and Gravely models that use the Warner-style clutch (5218-6, 5218-94, 717-3403, 917-3403, 09232700).

Fitment & Compatibility

Before buying, verify these three things:

• Measure your original clutch: The 8TEN Gen 3 has a 3.5” shaft diameter and 2.75” overall height. Measure your old clutch’s shaft bore and mounting hole spacing (typically 3.5” center-to-center).
• Check your model number: Works with Cub Cadet (e.g., LT1042, LT1050), MTD (e.g., 13A-325-190), Ariens (e.g., 915069), and Gravely (e.g., 991069) models using the listed OEM numbers. Cross-reference your machine’s manual or parts diagram.
• Electrical compatibility: Requires 12V DC power and a standard 2-wire connector (included). Ensure your mower’s wiring harness matches the supplied connector.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic mechanic skills, a puller tool for the old clutch, and a torque wrench (specs: 35-45 ft-lbs for the center bolt). Plan 1-2 hours.
• Quality notes: 3.8/5 rating suggests mixed feedback. Some users report shorter lifespan than OEM (2-3 seasons vs. 5+). Check for wobble or noise after install – a common issue is improper air gap (should be 0.010-0.015”).
• Gotcha: The included wiring harness may not match all machines – you might need to splice or replace connectors. Also, the clutch may require a break-in period (10-15 minutes of light use) to seat the friction plate.
• Warranty: Typically 1-year limited. Keep your receipt and old clutch for potential RMA.

Should You Buy It

Buy this if you’re on a budget and can handle basic wiring and mechanical work. It’s a decent value for older mowers where OEM parts cost 2-3x more. Skip it if you need maximum reliability for commercial use or want a plug-and-play fit without any modifications – stick with OEM or a higher-rated aftermarket brand.
