Popular Toro PTO Clutch Replacement Paths
Common Toro PTO clutch replacements include 110-6766, 103-0665, 103-0690, and 116-1620. Always confirm the original clutch number, bore size, pulley diameter, rotation, connector, and anti-rotation setup before ordering.
Toro Titan and TimeCutter PTO Clutch Fitment
Many Toro TimeCutter and Titan models use the 110-6766 PTO clutch family, but not every Toro zero-turn clutch is interchangeable. Model names such as TimeCutter Z5020, Titan ZX5020, Titan ZX5000, Titan Z4800, and Titan Z5200 can be confused in aftermarket listings, so always confirm the exact Toro model number and serial range.
For 110-6766 applications, confirm the 1-inch bore, 5.8 inch / 5-13/16 inch pulley, CCW rotation, 12 VDC coil, integral connector, and stop-bracket fit before installing the replacement clutch.
Toro Z Master and Commercial PTO Clutch Fitment
Toro Z Master and commercial mower applications often use different clutch paths than residential TimeCutter and Titan models. Some commercial units use larger bore sizes, different pulley diameters, heavier torque ratings, and different anti-rotation brackets. Do not substitute a Z Master clutch onto a Titan or TimeCutter unless the original clutch number and physical specs match.
For commercial Toro clutch routing, start with the Toro Z Master PTO clutch replacement guide.
Common Toro PTO Clutch Applications
These electric PTO clutch replacements are commonly used across Toro mower platforms including:
- Toro TimeCutter SS, Z, and ZS zero-turn mowers
- Toro Titan Z and Titan ZX zero-turn mowers
- Toro Z Master commercial zero-turn mowers
- Toro ProLine and Mid-Size commercial mower platforms
- Toro Groundsmaster and older commercial mower applications
- Selected Wheel Horse and legacy Toro-family mower platforms
Common Toro PTO Clutch Fitment Traps
Important fitment note: not every Toro PTO clutch is interchangeable. Older Toro, Wheel Horse, and Lawn-Boy numbers such as 124833, 539124833, 44-0770, and 54-0220 usually belong to a different replacement family than 110-6766. If your clutch shows one of those numbers, use the 124833 and 539124833 PTO clutch replacement guide.
If your Toro blades will not engage, the clutch clicks but the blades will not spin, or the clutch slips under load, confirm the clutch number before replacing parts.
