The ROP Shop Electric PTO Clutch fits Cub Cadet LT 1042 Lawn Tractors with 42" Deck

What It Is

This is an electric PTO (power take-off) clutch for Cub Cadet LT 1042 lawn tractors with a 42-inch deck. It engages and disengages the mower blades via an electromagnetic coil, allowing you to start/stop cutting without killing the engine.

Fitment & Compatibility

Before buying, verify these four things:

• Model & deck size: Confirmed fit for Cub Cadet LT 1042 with 42" deck. Will NOT fit LT 1042 with 54" deck (different clutch assembly).
• OEM cross-reference: Replaces Cub Cadet OEM part # 759-3886 and 759-3886A. Check your current clutch’s part number stamped on the metal housing.
• Electrical system: Requires 12V DC supply and a 2-wire connector (standard on LT 1042). Measure your existing clutch’s wire plug shape – some aftermarket versions use a different connector.
• Physical dimensions: Verify shaft diameter (typically 1” on LT 1042) and bolt pattern (3-bolt, 2.5” spacing). Measure your old clutch’s overall height – this aftermarket unit is 2.75” tall.

Key Things to Know

• Quality concerns: 3.7 stars from 14 reviews indicates mixed reliability. Some users report premature bearing failure after 1-2 seasons. Expect shorter lifespan than OEM.
• Installation difficulty: Moderate. Requires removing the drive belt, unbolting the old clutch (3 bolts), and wiring the new one. You’ll need a socket set, screwdrivers, and a jack to lift the tractor. Allow 1-2 hours.
• Common gotcha: The supplied wire harness may be too short on some LT 1042 models – check your existing wire length before cutting anything. Also, the clutch gap (air gap between rotor and armature) may need adjustment (0.010-0.015” feeler gauge) after install.
• Noise/vibration: Several reviews note louder engagement and slight vibration compared to OEM. Not a defect, but noticeable.

Should You Buy It

Buy this if you need a budget replacement for an LT 1042 with a 42” deck and are comfortable with moderate DIY installation and potential shorter lifespan. Skip it if you want OEM reliability, have a different deck size, or prefer a clutch with longer warranty coverage.
