OCPTY Electric PTO Clutch pto Clutch 070-1000-00 Replacement for Warner: 5218-114 5218-220 5218-83, for Bad Boy: 070-1000-00, for Stens: 255-775 Electric Mower Clutch

What It Is

This is an aftermarket electric PTO (power take-off) clutch designed to engage and disengage the mower blades on zero-turn and riding lawn mowers. It replaces failed OEM units on Bad Boy, Warner, and Stens applications, primarily for 48-inch to 72-inch deck models.

Fitment & Compatibility

Before buying, verify these three things:

• Measure your old clutch: This unit has a 1-inch bore, 3.5-inch outer diameter, and 5/16-inch keyway. Confirm your crankshaft matches.
• Check the mounting pattern: It uses a 3-bolt pattern on 3.125-inch centers. Measure bolt hole spacing on your mower deck or engine.
• Cross-reference your OEM part number: This replaces Warner 5218-114, 5218-220, 5218-83; Bad Boy 070-1000-00; Stens 255-775. If your machine uses a different series (e.g., 5218-100), it won’t fit.

Not compatible with Craftsman, Husqvarna, or MTD push mowers—this is for zero-turn and commercial riders only.

Key Things to Know

• Quality concerns: With only 3.3 stars from 4 reviews, expect inconsistent quality. Some users report short lifespan or premature bearing failure.
• Installation difficulty: Moderate. You’ll need a pulley puller, torque wrench (specs: 35-45 ft-lbs for center bolt), and a feeler gauge to set air gap (0.012-0.020 inches).
• Common gotcha: The supplied wiring harness may have different connector colors than your machine. You may need to splice or re-pin.
• No warranty support: OCPTY is a generic brand; returns or replacements are handled through the seller, not a manufacturer.

Should You Buy It

Only if you need a budget fix for an older Bad Boy or Warner-equipped mower and are comfortable with DIY installation and potential early replacement. For critical commercial use or if you want reliability, spend more on an OEM Warner or Stens clutch—this is a gamble, not a long-term solution.
