8TEN Gen 3 Electric PTO Clutch for MTD Cub Cadet Warner Simplicity 917-1709 717-1709 5215-130 5215-22 1706692SM

What It Is

The 8TEN Gen 3 Electric PTO Clutch engages and disengages your mower blades via an electromagnetic coil. It’s designed as a direct replacement for MTD, Cub Cadet, and Simplicity lawn tractors with Warner-style clutches.

Fitment & Compatibility

Before buying, verify your mower model uses a 3.5-inch (89mm) diameter clutch with a 1-inch (25.4mm) bore and 3-bolt mounting pattern. Cross-reference your OEM part number: 917-1709, 717-1709, 5215-130, 5215-22, or 1706692SM. This fits most Cub Cadet LT/LTX/GT series, MTD Yard Machines, and Simplicity Legacy/Regent models with 42–54-inch decks. Measure your existing clutch’s outer diameter and shaft bore – if they match, it’s likely compatible. Not for zero-turn mowers or older 2-bolt clutches.

Key Things to Know

• Quality vs OEM: Aftermarket design; some users report shorter lifespan than genuine Warner clutches under heavy use. Check warranty (typically 1 year).
• Installation difficulty: Moderate – requires removing the drive belt, unplugging the wiring harness, and torquing the center bolt to 35–45 ft-lbs. Have a puller tool ready if the old clutch is seized.
• Common gotcha: The wiring harness plug may be reversed polarity on some models – test blade engagement before reassembling the deck. If blades spin with the PTO off, swap the two wires.
• Noise: Gen 3 models are quieter than earlier revisions, but a slight hum when engaged is normal.

Should You Buy It

If you need a budget-friendly replacement for a worn PTO clutch on a mid-duty residential Cub Cadet or MTD tractor, this is a solid value. Skip it for heavy commercial use or if you want the longest possible lifespan – a genuine Warner clutch costs twice as much but lasts longer.
