Warner PTO  Clutch Cross Reference Simplified

Warner PTO clutches are among the most common found on both residential and commercial lawn mowers. If you own a John Deere, Cub Cadet, Exmark, or Grasshopper, there’s a good chance your mower rolled off the line with a Warner clutch installed.

When it’s time to replace one, though, part number searches can get messy — and most online “cross reference charts” are incomplete or inaccurate. The good news? Finding the right Warner replacement doesn’t have to be complicated.

Why Warner PTO Clutches Are Everywhere

• Warner supplies OEM clutches for major mower brands.
• They’re known for reliability — but OEM replacements can be expensive.
• That’s why many mower owners choose Ox Clutch replacements: they meet or exceed OEM performance at a fraction of the cost.

Step 1: Locate Your Warner Part Number

Warner PTO clutches typically have a small sticker or stamped number — for example, 5219-20, 5219-102, or 5219-77.

If you can’t find the sticker, check your mower’s owner’s manual or parts diagram. Use your model, serial number, and engine to cross-check for accuracy.

⚠️ Keep in mind: even within the same mower model, clutch specs can vary. Always compare your old clutch’s measurements (ID, pulley diameter, and rotation) against the replacement listing before ordering.

Step 2: Use the Search Bar on Our Website

Just enter your Warner part number into the search bar on our homepage.

You’ll instantly see results labeled “Replacement for Warner [Part Number]” — no confusing spreadsheets or outdated charts. Each product page includes full specs (ID, pulley diameter, and rotation) so you can confirm fitment before checkout.

Step 3: Verify Compatibility Before Ordering

Before completing your order, double-check:

• Crankshaft diameter (ID)
• Pulley diameter
• Mounting direction (CW/CCW rotation)

All of these are clearly listed on each product page.
