Stens 255-976 PTO Clutch Compatible with/Replacement for Hustler 605827K, Warner 5219-193 Pigtail Included, Belt Width 1/2" or 5/8", Pulley Diameter 5 3/4" Lawn Mowers Black

What It Is

The Stens 255-976 is an electric PTO clutch that engages and disengages the mower blades from the engine. It’s a direct replacement for Hustler and Warner clutches used on commercial zero-turn mowers, primarily Hustler models with 60” or 72” decks.

Fitment & Compatibility

Before buying, verify these four things:

• OEM cross-reference: Replaces Hustler 605827K and Warner 5219-193. Check your mower’s part number against these.
• Belt width: This clutch works with both 1/2” and 5/8” belts, but you must confirm which your mower uses. Measure your current belt width or check the deck manual.
• Pulley diameter: 5 3/4” – measure your old clutch pulley to ensure match. Different sizes affect belt tension and engagement.
• Pigtail connector: Includes a pigtail harness, but verify connector shape and pin configuration matches your mower’s wiring. Some Hustler models may need adapter or splicing.

Key Things to Know

• Quality: Stens is a reputable aftermarket brand, but this is not OEM. Expect similar performance at a lower price. Some users report slightly noisier operation than original Warner.
• Installation difficulty: Moderate. Requires basic mechanical skills, a puller tool, and torque wrench. You’ll need to remove the old clutch, align the new one, and set air gap (typically 0.010”–0.015”).
• Common gotcha: Air gap must be checked and adjusted after installation. Too tight causes drag; too loose causes slippage. Use feeler gauges.
• Belt width mismatch: If your mower uses 1/2” belt but you install with 5/8” belt, engagement will be poor. Measure twice.

Should You Buy It

If you need a reliable, cost-effective replacement for a Hustler or Warner PTO clutch and are comfortable with basic mechanical work (air gap adjustment, wiring check), this Stens unit is a solid choice. Avoid it if you want exact OEM fit with zero fuss or need a clutch for a non-Hustler/Deck brand without verifying dimensions.
