01001979P Electric PTO Clutch Fits for Cub Cadet M48 M54 M60 M72 ZT54 ZT60, for Recon 48 60, for MTD PRO MMZ-2554 MMZ-2560 Zero Turn Mowers; Replace 01001979 1001979P PET-0621, w/ Modular Wire

What It Is

This is an electric PTO (Power Take-Off) clutch that engages and disengages the mower blades on select Cub Cadet, MTD Pro, and Recon zero-turn mowers. Designed for residential and commercial mowers with 48–72-inch decks, it replaces the OEM part 01001979 and its equivalents.

Fitment & Compatibility

Before buying, confirm your mower’s model and deck size. This clutch fits:

• Cub Cadet: M48, M54, M60, M72, ZT54, ZT60
• Recon: 48, 60
• MTD PRO: MMZ-2554, MMZ-2560

Check your current clutch’s part number. This replaces OEM 01001979, 1001979P, and aftermarket PET-0621. Measure the clutch diameter (typically 4.5–5 inches) and shaft hole size (usually 1 inch). Verify the wire connector is modular (two-pin flat style) – this unit uses a modular wire. Also confirm your engine crankshaft length and PTO mounting bolt pattern (three or four holes). If your existing clutch has a different connector style, you may need an adapter or wiring modification.

Key Things to Know

• Quality: Aftermarket replacement; generally reliable for residential use but may not match OEM durability under heavy commercial loads.
• Installation: Moderate difficulty. Requires removing the mower deck, disconnecting battery, and using a puller tool to remove the old clutch. Torque the center bolt to manufacturer spec (typically 40–50 ft-lbs).
• Common gotchas: The modular wire may be shorter than OEM – check routing before install. If your mower has a different PTO switch or safety interlock system, the clutch may not engage if wiring is reversed.
• Warranty: Usually 1 year; verify with seller.

Should You Buy It

If you need a direct-fit replacement for a Cub Cadet or MTD Pro zero-turn with a 48–72-inch deck and your original 01001979 clutch has failed, this is a cost-effective option. It’s best for residential users and light commercial mowing. For heavy-duty daily commercial use, consider an OEM clutch for longer life.
