Warner 5218-213 PTO Clutch Guide

Warner 5218-213 PTO clutch guide featured image showing a Bobcat ProCat mower, 2721337 Bobcat replacement path, 1-1/8 inch bore, 6-5/16 inch pulley, CW rotation, and 200 ft-lb torque rating.

Overview

If your original PTO clutch is marked Warner 5218-213, this guide explains the correct replacement path, related OEM numbers, common cross references, and fitment checks before ordering.

The Warner 5218-213 is a heavy-duty commercial electric PTO clutch commonly connected to the Bobcat 2721337 replacement path. It is also associated with legacy Warner numbers 5218-65 and 5218-65E.

Warner 5218-213, 5218-65, and 5218-65E

Warner 5218-65 and 5218-65E are legacy references commonly routed to the modern 5218-213 replacement path.

  • 5218-213: modern Warner route
  • 5218-65: legacy Warner reference
  • 5218-65E: legacy Warner reference

If your old clutch tag shows 5218-65 or 5218-65E, treat that as a strong starting point, but still confirm the physical specifications and wiring setup before ordering.

Common OEM Cross-References

The Warner 5218-213 clutch family is used across multiple commercial mower brands. Some of these are exact physical clutch-body matches, but wiring harnesses and pigtail lengths can vary by brand.

Bobcat / Bob-Cat / Bunton Route

  • Bobcat: 2721337
  • Bob-Cat: 2721337
  • Bunton: 2721337

Exmark Route

  • Exmark: 103-0665
  • Exmark Legacy: 1-641300

Hustler Route

  • Hustler: 787366
  • Hustler Kit Reference: 787366K

Important: Exmark 103-0665 and Hustler 787366 may share the same physical clutch core as Warner 5218-213, but connector leads, pigtail lengths, polarity, and harness routing may differ by mower brand. Do not assume a brand-specific kit will plug directly into a Bobcat mower without verifying the wiring setup.

Aftermarket Cross-Reference Numbers

  • Xtreme: X0049
  • Stens: 255-552
  • Rotary: 11237
  • Oregon: 33-136
  • Prime Line: 7-06278

Aftermarket listings may group several brands into one large compatibility list. Use those numbers as cross-reference clues, not as a substitute for confirming the original clutch number, specs, and connector setup.

Buy the Correct PTO Clutch Replacement

If your original PTO clutch is marked Warner 5218-213, 5218-65, 5218-65E, or Bobcat 2721337, start by matching that number first. Then verify the 1-1/8 inch bore, 6-5/16 inch pulley, 5/8 inch belt, CW rotation, and wiring setup before ordering.

Do Not Confuse Warner 5218-213 With Warner 5219-14

Warner 5218-213 and Warner 5219-14 can look similar because both are commonly listed with a 1-1/8 inch bore, 6-5/16 inch pulley, 5/8 inch belt, and CW rotation. They are not interchangeable.

Warner Number Common OEM Path Torque Common Use
5218-213 Bobcat 2721337 200 ft-lbs 20HP+ commercial Bobcat applications
5219-14 Bobcat 2722016 125 ft-lbs 19HP and lighter applications

Installing a lower-torque clutch on a mower designed for a 200 ft-lb clutch can cause slipping, heat buildup, and early clutch failure. Installing the heavier clutch on a circuit designed for the lower-amp clutch can create electrical strain. Match the original clutch number and engine application before ordering.

For the side-by-side breakdown, see the 2721337 vs 2722016 Guide.

Bobcat 2720949 Pigtail Note

Many Bobcat applications using the 2721337 / Warner 5218-213 clutch path rely on an external pigtail harness. The Bobcat pigtail commonly associated with this route is 2720949.

Before replacing the clutch, inspect the pigtail and mower-side connector for:

  • Melted insulation
  • Heat discoloration
  • Green terminal corrosion
  • Loose or brittle connector housings
  • Short, stretched, or repaired wiring
  • Low voltage at the clutch connector

A damaged pigtail can reduce voltage reaching the clutch coil. That can make a correct new clutch slip, run hot, or fail early.

Compatible Application Notes

The Warner 5218-213 path is most commonly tied to higher-load commercial mower applications. It is especially important on large-deck machines where a lower-torque clutch may not hold under deck load.

Bobcat Applications

  • Bobcat 2721337 applications
  • Bobcat ProCat: select commercial applications
  • Bobcat Predator Pro: select commercial applications
  • Bobcat ZT200 Series: select 20HP-and-higher applications

Exmark and Hustler Applications

  • Exmark 103-0665 / 1-641300: physical clutch-body cross-reference path
  • Hustler 787366 / 787366K: physical clutch-body cross-reference path

For Exmark and Hustler applications, verify the original OEM number and wiring harness. The clutch core may match, but the supplied harness or connector may not be the same as the Bobcat setup.

Do Not Confuse With Bobcat 2721110

Warner 5218-213 should not be confused with the Bobcat 2721110 path. That is a different clutch route with different physical requirements.

  • Warner 5218-213 / Bobcat 2721337: 1-1/8 inch bore, 6-5/16 inch pulley, CW rotation
  • Bobcat 2721110 path: 1-inch bore, larger 7-inch class pulley, CCW rotation

If your original clutch uses a 1-inch bore or CCW rotation, this Warner 5218-213 path is not the correct replacement.

Before Ordering

Before ordering a Warner 5218-213 replacement, confirm:

  • Original clutch number stamped on the clutch tag
  • Whether the old clutch shows 5218-213, 5218-65, 5218-65E, or 2721337
  • Mower brand, model number, and serial number
  • Engine horsepower, especially on Bobcat applications
  • 1-1/8 inch crankshaft bore
  • 6-5/16 inch pulley diameter
  • 5/8 inch belt width
  • CW rotation from pulley side
  • Connector style and pigtail length
  • Condition of the clutch pigtail and mower wiring
  • Anti-rotation bracket or clutch stop setup
  • Deck belt path, idlers, spindle bearings, and pulley alignment

Common Symptoms of PTO Clutch Failure

  • Blades will not engage
  • PTO switch clicks but deck does not start
  • Clutch slips under heavy mowing load
  • Blades engage cold but stop after the mower heats up
  • Burning smell near the clutch or belt
  • Fuse blows when PTO is switched on
  • Melted pigtail or connector near the clutch
  • Bearing noise below the engine crankshaft
  • Deck belt smokes, jumps, or loses tension

Some electrical problems can mimic a failed PTO clutch. Test battery voltage, PTO switch output, ground continuity, and voltage at the clutch connector before replacing parts unnecessarily.

Installation Notes

  • Clean the crankshaft before installing the replacement clutch.
  • Inspect the crankshaft keyway and woodruff key.
  • Replace a damaged, mushroomed, or worn key.
  • Do not force the clutch onto a burred crankshaft.
  • Do not use an impact wrench on the center crankshaft bolt.
  • Use a torque wrench and follow the engine manufacturer's crankshaft bolt specification.
  • Confirm the anti-rotation bracket or clutch stop is aligned correctly.
  • Inspect the wiring pigtail before startup.
  • Burnish the clutch before mowing under full load.

To burnish the clutch, engage and disengage the PTO several times at reduced engine speed without cutting grass. This helps seat the rotor and armature friction surfaces before the clutch is exposed to full deck load.
