Important Bobcat 188019 vs. 2722016 Check

- Bobcat 2722016 Path: Warner 5219-14, 1-1/8-inch bore, approximately 6.31-inch pulley, CW rotation
Do not merge these listings or substitute one clutch for the other based the sneaky Warner number similarity.
View our separate listing for the Bobcat 2722016 / Warner 5219-14.
Before Ordering
- Read the complete part number from the original clutch label.
- Confirm the complete mower model and serial number.
- Measure the crankshaft diameter rather than estimating it visually.
- Measure the pulley across the outside diameter.
- Compare the pulley offset and belt-groove profile.
- Compare the wire length, terminals, polarity, and wire direction.
- Inspect the crankshaft key and anti-rotation bracket.
- Confirm whether an Exmark 1-551054 kit requires additional hardware.
- Do not substitute Bobcat 2722016 or Warner 5219-14 for this clutch.
- Do not operate the mower if the installed clutch contacts the frame, belt, wiring, exhaust, or anti-rotation hardware.
Common Symptoms of a Failing PTO Clutch
- Mower blades will not engage when the PTO switch is activated
- The clutch clicks but the deck belt does not begin turning
- Blades engage when cold but stop after the mower heats up
- The clutch slips during heavy or wet cutting conditions
- The deck belt squeals, smokes, or overheats during engagement
- Burning smell near the engine crankshaft or clutch
- Grinding, rumbling, or excessive pulley-bearing noise
- Intermittent blade engagement under load
- Visible heat damage around the coil, terminals, or wire leads
- Excessive looseness or roughness at the pulley bearing
A weak battery, charging-system problem, faulty PTO switch, damaged wiring, poor ground, slipping belt, seized spindle, worn idler, or incorrect belt tension can create similar symptoms. Diagnose the complete PTO and deck-drive systems before replacing the clutch.
