126-8926 electric PTO clutch used on Toro, Exmark, Ariens, and Gravely zero-turn mower platforms.
The 126-8926 PTO clutch is commonly used on commercial and heavy-duty zero-turn mower platforms including Toro, Exmark, Ariens, and Gravely machines. If your mower deck fails to engage, slips under load, or produces excessive noise during blade engagement, replacing the electric PTO clutch may restore normal operation.
What the 126-8926 PTO Clutch Does
An electric PTO clutch mounts to the engine crankshaft and engages the mower deck belt when the PTO switch is activated. When energized, the clutch uses electromagnetic force to lock the pulley assembly to the crankshaft, transferring engine power to the mower blades.
Commercial mowing equipment often experiences heavy operating loads and frequent engagement cycles. Over time, the clutch bearings, friction surfaces, and coil components can wear out, eventually requiring replacement.
