8TEN Gen 3 Electric PTO Clutch for Exmark Warner 917-3389 717-3389 5215-14 5215-68 04915400

What It Is

The 8TEN Gen 3 Electric PTO Clutch is an aftermarket replacement for Warner-brand PTO clutches used on Exmark mowers (and select other brands) to engage and disengage the mower blades via the electrical system. It’s designed for zero-turn and riding mowers in residential to light commercial use.

Fitment & Compatibility

Before buying, confirm your mower uses a Warner 917-3389, 717-3389, 5215-14, 5215-68, or 04915400 OEM clutch. This 8TEN Gen 3 replaces those directly. Check the clutch’s bolt pattern (typically 4-bolt, 3.25” center-to-center) and shaft diameter (1” or 1-1/8” – measure yours). Also verify the electrical connector type (single flat pin vs. round pin). It fits many Exmark Lazer Z, Quest, and Turf Tracer models, but always cross-reference your mower’s model and serial number with the manufacturer’s parts list. Deck size (42”, 48”, 52”, 60”) is irrelevant – it’s the clutch mounting and shaft that matter.

Key Things to Know

• Quality vs. OEM: This is a budget-friendly aftermarket unit. It works well for most users but may have a shorter lifespan than a genuine Warner or Ogura clutch under heavy daily commercial use.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, torque wrench) and should disconnect the battery first. The hardest part is often removing the old clutch’s retaining bolt (may require an impact driver).
• Common gotcha: The electrical connector may not match your mower’s harness exactly – you might need to splice or swap the connector. Also, the air gap is pre-set, but verify it (0.010”–0.015”) with a feeler gauge after install.
• Warranty: Typically 1-year limited. Keep your receipt and original packaging for returns.

Should You Buy It

If you have an Exmark with a failed Warner clutch and want a reliable replacement without paying OEM prices ($200+), this is a solid choice for homeowner or light commercial use. For heavy daily commercial operation, a genuine Warner or Ogura clutch is a better long-term investment.
