Bobcat ProCat Fitment Guide

Overview

If you're replacing the PTO clutch on a Bobcat ProCat, the main clutch path to verify is Bobcat 2721337, commonly tied to the Warner 5218-213 heavy-duty PTO clutch route.

The ProCat is a commercial mower platform, so fitment should not be handled by appearance alone. Many ProCat applications use the heavy-duty 200 ft-lb clutch path designed for larger commercial decks and higher-horsepower engines.

Use this guide to confirm the Bobcat ProCat PTO clutch route, common model notes, Warner cross references, 19HP warnings, pigtail checks, and installation points before ordering.

Bobcat ProCat PTO Clutch Route

For select Bobcat ProCat applications, the correct PTO clutch route is:

• Bobcat / Bob-Cat OEM Number: 2721337
• Warner Number: 5218-213
• Legacy Warner References: 5218-65, 5218-65E
• Torque Rating: 200 ft-lbs

Common Bobcat ProCat Applications

The 2721337 clutch path is associated with select higher-horsepower Bobcat ProCat commercial applications. Always confirm your original clutch number, model number, serial number, deck size, engine horsepower, and wiring setup before ordering.

Key Specifications for the ProCat 2721337 Path

Why ProCat Applications Commonly Use the Heavy-Duty Path

Bobcat ProCat mowers are commercial machines with heavier deck loads than many residential or light-duty mower platforms. A clutch used on a ProCat must hold the deck belt under load without slipping during engagement.

The 2721337 / Warner 5218-213 route is the heavy-duty Bobcat clutch path rated at 200 ft-lbs. That higher holding torque matters on larger commercial deck systems where a lower-torque clutch can slip, overheat, glaze the friction surfaces, or fail early.

For a broader comparison between the 200 ft-lb and 125 ft-lb Bobcat paths, see the 2721337 vs 2722016 Guide.

Critical 19HP Warning

Stop before ordering: if your Bobcat mower has a 19HP engine, do not automatically order the 2721337 clutch.

The 2721337 / Warner 5218-213 route is generally the heavy-duty path for 20HP-and-higher Bobcat commercial applications. Bobcat 19HP applications commonly route to the 2722016 / Warner 5219-14 path instead.

If your ProCat lookup or mower tag creates confusion, match the original clutch number first. Do not choose the clutch by model-family name alone.

2720949 Pigtail and Wiring Check

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

Before installing a new PTO clutch on a ProCat, inspect the pigtail and mower-side wiring for:

• Melted insulation near the clutch
• Green corrosion inside the terminals
• Brittle connector housings
• Loose or overheated terminals
• Short, stretched, or repaired wiring
• Previous splices or non-OEM connector repairs
• Low voltage at the clutch connector

A damaged pigtail can reduce voltage to the clutch coil. That can make a correct new clutch slip, run hot, or fail early. If the pigtail is heat-damaged, cracked, corroded, or previously repaired, address the wiring problem before putting the new clutch under load.

Common Cross-Reference Numbers

The Bobcat ProCat 2721337 route may be searched under several OEM, Warner, and aftermarket numbers.

Primary Route

• Bobcat / Bob-Cat: 2721337
• Warner: 5218-213
• Warner Legacy: 5218-65, 5218-65E

Aftermarket References

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

Aftermarket listings may group Bobcat, Exmark, Hustler, and other brands together. Use those references as fitment clues, not as a replacement for checking the original clutch number, pigtail setup, and mower-specific wiring.

Buy the Correct PTO Clutch Replacement

If your Bobcat ProCat 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, connector style, pigtail setup, and engine horsepower before ordering.

Do Not Confuse With 2722016

The 2722016 / Warner 5219-14 path is not the same as the ProCat 2721337 heavy-duty route.

Both paths may appear similar because they can share a 1-1/8 inch bore, 6-5/16 inch pulley, 5/8 inch belt, and CW rotation. They are not interchangeable by appearance. Confirm the torque path, engine horsepower, and connector setup.

Do Not Confuse With Bobcat 2721110

Do not confuse the ProCat 2721337 path with Bobcat 2721110. The 2721110 route is a different clutch path with different bore, pulley, and rotation requirements.

• 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 CCW rotation, this ProCat 2721337 path is not the correct replacement.

Common Symptoms of PTO Clutch Failure on a ProCat

• Blades will not engage
• PTO switch clicks but deck does not start
• Clutch slips when the deck is loaded
• Blades engage cold but stop after the mower heats up
• Burning smell near the clutch or belt
• Fuse blows when the PTO is engaged
• Pigtail or connector melts near the clutch
• Deck belt smokes, jumps, or loses tension
• Bearing noise below the engine crankshaft
• Deck engagement feels weak or delayed

Some symptoms that look like a failed clutch can come from weak voltage, damaged wiring, a bad PTO switch, poor ground, seized idlers, bad spindle bearings, or incorrect belt tension. Inspect the system before replacing the clutch alone.

Before Ordering

Before ordering a Bobcat ProCat PTO clutch replacement, confirm:

• Original clutch number stamped on the clutch tag
• Whether the old clutch shows 2721337, 5218-213, 5218-65, or 5218-65E
• Mower model number and serial number
• Deck size
• Engine horsepower
• Whether the application 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
• Connector style and pigtail length
• Condition of the 2720949-style pigtail, 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 PTO clutch can fail early if the crankshaft, wiring, deck belt system, or installation process is wrong.

• Clean the crankshaft before installation.
• Inspect the crankshaft keyway and woodruff key.
• Replace a worn, mushroomed, or damaged key.
• Do not force the clutch over 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 clutch stop or anti-rotation bracket is aligned correctly.
• Inspect the pigtail and connector before startup.
• Check battery voltage and PTO switch output at the clutch connector.
• 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 full-load mowing.
