HD Switch HiTorque 210ftlb (OEM 175) BIGBearing Billet Pulley PTO Blade Clutch 71410020 Upgrade fits Wright Stander 71410020 WS42 48 52 61, WSPX48 52 61, WSTX48 52 61 Large Frame Stander X, Sport X

What It Is

This is a heavy-duty aftermarket PTO blade clutch designed for Wright Stander large-frame zero-turn mowers. It replaces OEM part 71410020 and delivers 210 ft-lb of torque, making it suitable for demanding commercial mowing where stock clutches may slip or wear prematurely.

Fitment & Compatibility

Before buying, confirm your Wright model is one of these: Stander WS42, 48, 52, 61; WSPX48, 52, 61; WSTX48, 52, 61; or Large Frame Stander X/Sport X. This clutch is not a direct drop-in for non-Wright machines or smaller-frame Wright models. Measure the PTO shaft diameter (typically 1" on these models) and verify your deck pulley bolt pattern matches the billet pulley’s mounting holes. The OEM 71410020 part number on your existing clutch is the best confirmation. If your Wright has a different OEM number, measure carefully or contact the seller.

Key Things to Know

• Torque upgrade: 210 ft-lb vs. OEM ~175 ft-lb means better engagement and less slip under heavy grass or wet conditions.
• Billet pulley: Machined aluminum is more durable than stamped steel; resists warping and cracking over time.
• Installation difficulty: Moderate. Requires basic mechanical skills, a puller for the old clutch, and torque wrench for the center bolt (typically 60-80 ft-lb). Wiring is plug-and-play if using the existing harness.
• Common gotcha: The “BIGBearing” design may require a slight spacer or shim if your deck has a recessed mounting area—check clearance before tightening.

Should You Buy It

If you run a Wright large-frame Stander commercially, this clutch is a solid upgrade over a worn OEM unit. The extra torque and billet pulley justify the higher price for mowers that see daily use or heavy cutting. For light residential use, the OEM clutch usually suffices.
