The ROP Shop Electric PTO Clutch for John Deere Lawn Tractor w/ 30/38" Mower Deck 165 170 175

What It Is

This is an electric PTO (power take-off) clutch that engages and disengages the mower blades on select John Deere lawn tractors with 30- or 38-inch decks. It’s a direct replacement for a worn or failed OEM clutch.

Fitment & Compatibility

Verify these before buying:

• Models: Fits John Deere 165, 170, and 175 lawn tractors (check your model number under the seat or hood).
• Deck size: Works with 30-inch and 38-inch mower decks only. Not for 42-inch or larger decks.
• OEM cross-reference: Replaces John Deere part numbers AM105226, AM105226A, AM105226B, AM105226C. Confirm your old clutch’s part number.
• Electrical: 12V DC, single-wire connection (ground through the clutch housing). Measure the wire connector type to match your harness.
• Physical dimensions: 4.5-inch outer diameter, 1-inch bore shaft, 3-bolt mounting pattern (holes on 3.25-inch centers). Measure your existing clutch’s bolt pattern and shaft diameter to be sure.

Key Things to Know

• Aftermarket fit: This is a non-OEM part. It may require minor adjustments (e.g., shimming the air gap) to align perfectly. Expect 0.010–0.025 inch air gap between the clutch and rotor.
• Installation difficulty: Moderate. You’ll need basic hand tools (socket set, torque wrench) and a puller to remove the old clutch. Wiring is straightforward—single wire to the PTO switch.
• Common gotcha: If your tractor has a 1-inch shaft but a different bolt pattern (some 170/175 models used a 2-bolt pattern), this won’t fit. Measure before ordering.
• Quality: Budget aftermarket—generally reliable for light residential use, but may not last as long as OEM under heavy or frequent mowing.

Should You Buy It

If you have a confirmed-fit John Deere 165, 170, or 175 with a 30/38-inch deck, and you’re on a budget, this is a solid, low-cost replacement. It’s best for occasional mowing or as a temporary fix. For heavy commercial use or exact OEM fit, spend more on a genuine John Deere clutch.
