SCITOO Electric PTO Clutch 717-04174A Electric PTO Lawn Mower Clutch Compatible for Cub Cadet, for Huskee, for MTD, for Sears, for Troy Bilt, for Warner, for Xtreme

What It Is

The SCITOO 717-04174A is an aftermarket electric PTO clutch that engages and disengages the mower blades via an electromagnetic coil. It’s designed for riding lawn tractors and zero-turn mowers from Cub Cadet, Huskee, MTD, Sears, Troy-Bilt, and others that use a 4-inch, 1-inch shaft PTO system.

Fitment & Compatibility

Before buying, verify three things:

• Shaft diameter: Must be 1 inch (25.4 mm) – measure your existing clutch’s center hole.
• Bolt pattern: Typically 4-bolt, 4.5-inch center-to-center – check yours.
• Wiring: 2-wire connector; confirm plug shape matches your harness (some MTD/Cub Cadet models use a flat 2-pin).

Cross-reference your model number with SCITOO’s list: fits Cub Cadet LTX1040, GT1554, RZT50; MTD 13A-326-190; Troy-Bilt 13WX78KS011; Huskee 13BT606G755. Not compatible with 3-inch or 1.125-inch shaft clutches (common on older John Deere or Gravely). Measure your old clutch’s overall thickness too – this unit is 2.15 inches tall. If your deck is 42–54 inches, it’s likely a match.

Key Things to Know

• Aftermarket quality: SCITOO is a budget brand; some users report shorter lifespan (1–2 seasons) vs. OEM Warner or MTD clutches. Inspect for loose screws or uneven gap on arrival.
• Installation difficulty: Moderate – you’ll need a puller to remove the old clutch and a torque wrench (spec is 30–40 ft-lbs on the shaft nut). Disconnect battery first.
• Common gotchas: The air gap (0.010–0.015 inch) may need adjusting after install. If blades slip or don’t engage, check gap with a feeler gauge. Also, the included hardware may not match your tractor – keep your old bolts.
• Noise: Some users note a slight whine or rattle on engagement; normal for aftermarket, but louder than OEM.

Should You Buy It

Buy this if you need a quick, low-cost replacement for a mid-size riding mower (42–54 inch deck) and don’t mind swapping it again in a couple years. It’s a good fit for DIYers who want to save $50–70 over OEM Warner or Cub Cadet clutches. Skip it if you mow commercially, have a heavy-duty zero-turn, or want a 5+ year part – go with OEM or a premium aftermarket like Stens.
