Overview
If your original clutch is marked Bobcat 2721337, Bob-Cat 2721337, Bunton 2721337, or Warner 5218-213, this guide explains the correct replacement path and the most important fitment checks before ordering.
The 2721337 PTO clutch is the heavy-duty Bobcat clutch path used on select commercial zero-turn applications, including many higher-horsepower Bobcat ProCat, Bobcat Predator Pro, and ZT200-series machines. It is a 200 ft-lb clutch path and should not be confused with the lower-torque 2722016 / Warner 5219-14 path used on 19HP applications.
Do not order by appearance alone. Match the original clutch number first, then confirm engine horsepower, crankshaft bore, pulley diameter, belt width, rotation, connector style, pigtail setup, and anti-rotation bracket before ordering.

Critical 19HP Fitment Warning
Stop before ordering: if your Bobcat mower has a 19HP engine, do not assume the 2721337 clutch is correct.
The 2721337 / Warner 5218-213 path is the heavy-duty 200 ft-lb route for many 20HP-and-higher Bobcat commercial applications. Bobcat 19HP applications commonly route to the lower-torque 2722016 / Warner 5219-14 clutch instead.
For a side-by-side breakdown, see the 2721337 vs 2722016 Guide.

- Hustler: 787366, 787366K
Important wiring note: Exmark 103-0665 and Hustler 787366 may share the same physical clutch body family as the Bobcat 2721337 path, but harness length, connector style, pigtail routing, and polarity may vary by mower brand and model. Bobcat buyers should order by the Bobcat 2721337 path and verify the original pigtail setup before installation.
Buy the Correct PTO Clutch Replacement
If your original PTO clutch is marked 2721337, 5218-213, 5218-65, or 5218-65E, 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 (from pulley side), connector style, and engine horsepower before ordering.

2720949 Pigtail and Wiring Check
Many Bobcat 2721337 applications use an external pigtail harness between the clutch and the mower wiring harness. The Bobcat pigtail commonly referenced with this clutch path is 2720949.
Before installing a new clutch, inspect the existing pigtail and wiring for:
- Melted insulation near the clutch
- Green corrosion inside terminals
- Loose or brittle connector housings
- Short or stretched wiring near the engine
- Previous splices or non-OEM repairs
- Low voltage at the clutch connector
A weak or damaged pigtail can reduce voltage to the clutch coil. That can make a new clutch slip, run hot, or fail early even when the clutch itself is correct.
Do Not Confuse With 2722016
The Bobcat 2722016 path is not just another label for 2721337. It is a different clutch route commonly tied to 19HP Bobcat applications and Warner 5219-14.
| Part Number | Warner Number | Torque | Typical Route |
|---|---|---|---|
| 2721337 | 5218-213 | 200 ft-lbs | Bobcat 20HP+ commercial applications |
| 2722016 | 5219-14 | 125 ft-lbs | Bobcat 19HP and lighter applications |
Because both paths can share similar bore and pulley dimensions, do not choose between them by appearance alone. Match the original clutch number and engine horsepower.
Do Not Confuse With Bobcat 2721110
Do not confuse the 2721337 path with Bobcat 2721110. The 2721110 path is a different clutch used on different Bobcat applications.
- 2721337: 1-1/8 inch bore, 6-5/16 inch pulley, CW rotation
- 2721110: 1-inch bore, larger 7-inch class pulley, CCW rotation
If your original clutch uses a 1-inch bore or counter-clockwise rotation, this 2721337 path is not the correct replacement.
Common Symptoms of PTO Clutch Failure
- Mower blades will not engage
- PTO switch clicks but blades do not spin
- Blades engage cold but stop after the mower heats up
- Clutch slips under heavy deck load
- Burning smell near the clutch or belt
- Fuse blows when the PTO is engaged
- Connector or pigtail is melted near the clutch
- Deck belt smokes, jumps, or loses tension
- Grinding, squealing, or bearing noise below the engine
Before Ordering
Before ordering a Bobcat 2721337 replacement, confirm:
- Original clutch number stamped on the clutch or label
- Mower brand, model number, and serial number
- Engine horsepower, especially whether the mower is a 19HP variant
- 1-1/8 inch crankshaft bore
- 6-5/16 inch pulley diameter
- 5/8 inch belt width
- CW rotation from pulley side
- External pigtail / connector style
- Condition of the 2720949-style pigtail harness, if equipped
- Anti-rotation bracket or clutch stop setup
- Deck belt path and pulley alignment
- Condition of idlers, spindle bearings, battery, PTO switch, and wiring
Installation Notes
A correct clutch can fail early if the installation or surrounding mower system is wrong.
- Clean the crankshaft before installing the replacement clutch.
- Inspect the keyway and replace a worn or damaged woodruff key.
- Do not force the clutch over a mushroomed key or burred crankshaft.
- Do not tighten the center bolt with an impact wrench.
- Use a torque wrench and follow the engine manufacturer's crankshaft bolt specification.
- Inspect the clutch stop or anti-rotation bracket before startup.
- Check battery voltage and PTO switch output at the clutch connector.
- Burnish the clutch before mowing under load.
For burnishing, engage and disengage the PTO several times at reduced engine speed without cutting grass. This helps the rotor and armature friction surfaces seat properly before the clutch is placed under full mowing load.
