FAQ
Does this PTO clutch replace Bobcat 2721337?
Yes. This aftermarket clutch is offered as a replacement for Bobcat / Bob-Cat and Bunton 2721337 on supported applications. Match your original clutch number and physical configuration before ordering.
Does this fit Bobcat 942223A?
This clutch is listed for the 942223A ZT223 application using 2721337. Confirm your complete model and serial number, particularly if the mower has received an engine replacement or other modifications.
Does this clutch also replace Bobcat 2188151?
Yes. This aftermarket replacement supports the listed 2188151 applications. Bobcat superseded that OEM number to 2721337, so your original clutch or older parts manual may show 2188151 while a current parts lookup shows 2721337. Confirm your mower configuration before ordering.
What should I check on a 19-hp Bobcat?
Check the clutch number in the parts diagram for your exact model and serial number. Certain ZT200 configurations use a different clutch for the 19-hp engine. Horsepower alone is not enough to identify the correct replacement.
Does this fit every ProCat or Predator Pro?
No. These mower families include different engines and clutch configurations. This listing covers select applications specifying the OEM or manufacturer references listed above.
Does this replace Warner 5218-213, 5218-65, or 5218-65E?
These Warner numbers are listed within this replacement application family. Warner identifies 5218-213 as a replacement for 5218-65. Compare the original clutch and wiring configuration before ordering.
Why do some reference specifications list a 6.3-inch pulley?
Warner lists a 6.31-inch outside diameter for its 5218-213 clutch. The aftermarket unit offered here has a measured outside diameter of approximately 6.125 inches.
Outside diameter and the working diameter where the belt rides are different measurements. For belt speed, the critical measurement is that working diameter—not the outer flange edge. This aftermarket clutch is designed to replace the OEM and manufacturer part numbers listed here.
What bore size does this clutch use?
This clutch has a 1-1/8-inch crankshaft bore, also written as 1.125 inches. Match the bore and key arrangement to your original clutch.
Is this a reverse-mount clutch?
Yes. This replacement uses a reverse-mount configuration. Follow the mounting orientation and spacer arrangement specified for your mower. Product-photo orientation is not an installation diagram.
What connector does this clutch use?
The clutch has a flat side-by-side connector. An optional wire harness extends the connection to a T-plug. Some Bobcat installations use a jumper harness between the clutch and mower wiring, so compare both ends of your existing connection.
What belt should I use?
Use the OEM-specified belt for your exact mower and deck configuration. Supported applications commonly use a 5/8-inch V-belt. Belt width, length, and profile must suit the complete drive system.

Yes. We provide fitment support before and after purchase. Email support@ptodirectusa.com with your mower model, serial number, engine information, and original clutch number. Include photos of the clutch label, bore, pulley, wiring connector, jumper harness, and anti-rotation connection.
