What It Is

This is an electric PTO (power take-off) clutch that engages and disengages the mower blades on your lawn tractor. It’s designed for Cub Cadet 2000, 2130, 2135, 2138, 2143, 2145, GT2542, and LT2138 models, typically found on mid-to-late 1990s and early 2000s garden tractors.

Fitment & Compatibility

Before buying, confirm your mower’s model number (not just series) and deck size—this clutch fits 42-inch and 50-inch decks on the listed models. The replacement part numbers to cross-reference are 717-3385, 717-3385A, 717-3385AP, 717-3385B, 917-3385, 5217-14, 5217-42, and 917-3385B. Measure your original clutch’s shaft diameter (typical is 1 inch) and bolt pattern (three holes, 2.5-inch spacing) to ensure physical match. This is an aftermarket replacement, not OEM Cub Cadet, so verify your mower uses a 12-volt electrical system and a two-wire connector (common on these models).

Key Things to Know

• Quality: With a 5.0 rating from a single review, reliability is unproven at scale. Expect it to work, but be aware aftermarket clutches can have shorter lifespans than OEM.
• Installation difficulty: Moderate—requires basic mechanical skills, a socket set, and a puller tool for the old clutch. Disconnect the battery first to avoid electrical shorts.
• Common gotchas: The air gap (between clutch and rotor) must be set to 0.010–0.015 inches after installation—use a feeler gauge. Also, check your PTO belt condition and tension; a worn belt can cause premature clutch failure.
• Wiring note: If your mower has a different connector style, you may need to splice or replace the plug. The clutch comes with a standard two-pin connector.

Should You Buy It

If you own one of the listed Cub Cadet models and your original PTO clutch is seized, slipping, or won’t engage, this is a budget-friendly alternative to OEM (which costs $120–$150). It’s right for DIYers comfortable with a weekend repair, but if you want guaranteed longevity or have a less common model, stick with an OEM part from Cub Cadet.
