If your Exmark Yellow Jacket YJ2348 blades are not engaging, slipping under load, or cutting inconsistently, a worn PTO clutch is one of the most common causes. These compact and specialty mower platforms rely on consistent clutch engagement to drive the mower deck and maintain proper cutting performance.
This guide explains PTO clutch fitment, common failure symptoms, and how to identify the correct replacement for Yellow Jacket mower applications.
Exmark Yellow Jacket YJ2348 PTO Clutch Replacement
The PTO clutch on the Exmark Yellow Jacket YJ2348 mounts directly to the engine crankshaft and engages the mower deck belt when the PTO switch is activated. This electromagnetic clutch must engage cleanly and consistently to maintain blade speed and cutting performance.
As the clutch wears, internal components such as bearings and friction surfaces degrade, leading to slipping, overheating, or complete failure to engage.
Many Yellow Jacket applications use PTO clutches that fall within the same cross-reference group as 110-6766 PTO clutch, which is also widely used across Toro, Exmark, Ariens, and Gravely mower platforms.
This clutch platform also cross-references with OEM numbers including 100-6059, 103-9950, 108-9510, 5219-81, 5219-45, and 5219-34A.

Common Signs of a Failing PTO Clutch on Yellow Jacket

Where Is the PTO Clutch Located?
The PTO clutch is mounted beneath the engine crankshaft and sits above the mower deck belt system. When engaged, it transfers power from the engine to the cutting blades.
Access typically requires lifting the mower or removing surrounding components to inspect the clutch assembly.
