HiTorque 210ftlbs (OEM 175) BIGBearing Solid Steel Billet Pulley Electric PTO Clutch 5218-5 Replaces Warner 5218-5 with Larger Replaceable Pulley Bearing and Bearing Upgrade Lawn Mower 52185

What It Is

This is a heavy-duty electric PTO (power take-off) clutch pulley for lawn mowers, designed to engage and disengage the mower deck blades. It delivers 210 ft-lbs of torque (vs. OEM 175 ft-lbs) and features a solid steel billet pulley with an oversized, replaceable bearing—ideal for commercial or high-use residential mowers.

Fitment & Compatibility

• Direct OEM replacement for Warner 5218-5 (part #52185). Fits many brands using this Warner clutch, including certain John Deere, Cub Cadet, Husqvarna, and MTD models.
• Before buying: Measure your existing clutch’s bolt pattern (typically 3-bolt, 4.5” center-to-center), shaft diameter (commonly 1”), and overall pulley diameter. Compare to your mower’s deck clearance—this billet pulley may be slightly larger than a stamped steel OEM.
• Not universal: Verify your mower’s model number and deck size (42”, 48”, 54”, etc.) against HiTorque’s fitment list. If your OEM clutch is a different Warner model (e.g., 5218-1 or 5218-2), this won’t interchange without adapter.

Key Things to Know

• Torque upgrade: 210 ft-lbs vs. OEM 175 ft-lbs means stronger engagement and less slippage under heavy grass, but verify your mower’s PTO shaft and wiring can handle the extra load.
• Replaceable bearing: The large bearing is serviceable—you can swap it out without replacing the whole clutch, extending life. Standard stamped steel clutches require full replacement.
• Installation: Moderate difficulty. You’ll need basic hand tools, a multimeter to test coil resistance (typically 3–4 ohms), and may need to adjust the air gap (0.010”–0.015”). Wiring is direct plug-and-play if your connector matches (usually 2-pin flat).
• Gotcha: The billet pulley is heavier than OEM—this can stress the PTO shaft bearings over time if your mower isn’t designed for it. Check shaft play before installing.

Should You Buy It

Yes, if you have a compatible mower and want a clutch that outlasts OEM stamped steel units—especially for commercial mowing or tough, wet grass. The replaceable bearing and higher torque justify the premium over a standard $80–100 replacement. Skip it for a budget mower you plan to replace soon.
