VEVOR Slip Clutch, 1 3/8" PTO Slip Clutch, Smooth Round Ends PTO Friction Clutch, Carburized Steel Tractor Slip Clutch, Adjustable Rotary Cutter Slip Clutch, Black Brush Hog Slip Clutch for PTO Shaft

What It Is

The VEVOR Slip Clutch protects your PTO-driven implement (e.g., brush hog, rotary cutter, tiller) and tractor driveline from shock loads and sudden jams. It’s designed for 1 3/8” PTO shafts with smooth round ends, common on compact tractors, sub-compacts, and older machines.

Fitment & Compatibility

Before buying, check:

• PTO shaft end: Must be 1 3/8” diameter with smooth round ends (not splined or star-shaped). If your shaft has a cross-hole or keyway, this clutch won’t fit without an adapter.
• Implement type: Best for light-to-medium-duty rotary cutters, flail mowers, and tillers up to ~40 HP. Not for heavy-duty bushhogs or high-torque applications over 50 HP.
• Bolt pattern: The clutch connects via four bolts to your implement’s gearbox input. Measure center-to-center bolt spacing (typically 2” or 2.5”)—this unit uses a standard 2” square pattern.
• OEM vs aftermarket: A direct replacement for many OEM slip clutches (e.g., Woods, Bush Hog, Land Pride) but verify your current clutch’s bolt pattern and shaft type.

Key Things to Know

• Quality: Carburized steel construction is durable for the price, but the friction discs are thinner than premium brands. Expect shorter service life under heavy use.
• Installation: Easy bolt-on for basic DIYers. You must adjust the spring tension (usually 4-6 bolts) to set slip torque—too loose and it slips constantly, too tight and it won’t protect your driveline. A torque wrench is recommended.
• Common gotcha: The smooth round ends may not fit European or older odd-size PTO shafts. Also, the clutch can rust if left exposed—store it dry or apply anti-seize on the disc faces.
• Noise: Some users report a squeaking or chirping sound during operation until the discs break in. This is normal.

Should You Buy It

This clutch is a solid budget-friendly option for weekend-warrior mowing on compact tractors and light-duty implements. If you’re running a heavy commercial bushhog or need a high-cycle-lifetime part, step up to a premium brand (e.g., Weasler or Neapco). For the price, it’s hard to beat if your fitment matches.
