Electric PTO Clutch for Warner Cub Cadet MTD Gravely 5218-6 5218-94 717-3403 917-3403 09232700

What It Is

This electric PTO (power take-off) clutch engages and disengages the mower blades on select Cub Cadet, MTD, Gravely, and Warner zero-turn and lawn tractors. It’s an aftermarket replacement for OEM part numbers 5218-6, 5218-94, 717-3403, 917-3403, and 09232700.

Fitment & Compatibility

Before buying, confirm your mower uses a 3/4-inch bore shaft and a single-wire electric engagement system. This clutch is a direct swap for Warner PTO clutches found on Cub Cadet RZT, Z-Force, and MTD/Gravely ZT models from the early 2000s to mid-2010s. Measure the clutch diameter (typically 4.5 inches) and bolt pattern (3-hole, 2.75-inch spacing) to match your existing unit. It will not fit zero-turns with a 1-inch shaft or two-wire clutches. Always verify your mower’s model number against the OEM part list.

Key Things to Know

• Build quality: Aftermarket unit with solid reviews (4.4 stars), but may have slightly less durable bearing than OEM Warner. Expect 2–3 seasons under residential use.
• Installation difficulty: Moderate. Requires removing the mower deck, supporting the PTO shaft, and torquing the center bolt to 35–45 ft-lbs. No special tools beyond a socket set and a puller for the old clutch.
• Common gotcha: The included hardware may not match your mower’s bolt length—check if you need to reuse original bolts. Also, the clutch gap (air gap between rotor and armature) should be 0.010–0.020 inches; if it’s too tight, the clutch may drag or fail to engage.
• Wiring: Single-wire design—connect the lead to your mower’s PTO switch wire. Ground is through the clutch body to the engine block. No polarity issues.

Should You Buy It

If you need a budget-friendly replacement for a worn Warner PTO clutch on a residential Cub Cadet, MTD, or Gravely zero-turn, this is a solid choice. It’s not built for heavy commercial use, but for homeowners mowing a few acres, it offers reliable performance at a fair price. Skip it if you have a two-wire system or a 1-inch shaft.
