Replacement Specs to Confirm

- 126-8926

- 05191600

Do Not Confuse 126-8926 With Other Toro PTO Clutches
Toro uses multiple PTO clutch families across TimeCutter, Titan, Titan HD, Z Master, GrandStand, Groundsmaster, and older ProLine platforms. Do not order by brand name alone.
126-8926 is not the same as every Toro Titan or TimeCutter clutch. Many residential Toro TimeCutter and standard Titan models use different clutch families, connector styles, pulley offsets, or deck-drive layouts.
126-8926 is also not the older 124833 / 539124833 / 54-0220 family. Those numbers are tied to a different 1-inch bore, approximately 5.35-inch pulley clutch family. If your original clutch shows one of those numbers, see the 124833 and 539124833 PTO clutch cross-reference guide instead.
126-8926 is not the same as the 110-6766 family. The 110-6766 clutch family is commonly tied to selected Toro TimeCutter, Titan, Exmark Quest, Ariens, and Gravely applications with different fitment requirements. If your original clutch shows 110-6766, 103-9950, 100-6059, 108-9510, or Warner 5219-series numbers, start with the 110-6766 PTO clutch fitment guide.
Compatibility alert: A clutch with the wrong bore, pulley diameter, pulley offset, rotation, connector, or bracket position can cause belt misalignment, belt throw-off, weak blade speed, wiring problems, or premature clutch failure.
Common Symptoms of a Failed 126-8926 PTO Clutch
A failing PTO clutch can cause blade engagement problems, slipping, heat, noise, or electrical symptoms.
- Mower blades will not engage
- PTO clutch clicks but blades do not spin
- Deck belt does not move when PTO is activated
- Blades engage, then slow down under load
- PTO clutch gets hot or smells burnt
- Clutch works cold but fails after warming up
- Grinding, bearing noise, or pulley wobble near the clutch

If the blades will not engage at all, start with the PTO clutch won’t engage troubleshooting guide. If the clutch clicks but the blades do not spin, use the PTO clutch clicks but blades won’t spin guide. If the clutch slips under load, see the PTO clutch slipping under load guide. If the clutch gets hot or smells burnt, read the PTO clutch getting hot or smells burnt guide.
How to Confirm the Correct Replacement
Before ordering a replacement for 126-8926, inspect the original clutch and mower setup carefully.

- Confirm the bore size: This family uses a 1-1/8 inch crankshaft bore.
- Measure the pulley diameter: Confirm the pulley is approximately 7.20 inches.
- Compare pulley offset: Make sure the deck belt path lines up correctly.
- Check wiring style: Compare the connector, lead length, and wire condition.
- Check the anti-rotation bracket: Confirm the bracket position matches the mower setup.
- Confirm mower model and serial number: Deck size and production year can affect fitment.
Not sure where to find the part number? Use the PTO clutch fitment guide before ordering.
Before Installing the New PTO Clutch
Before installing a new clutch, inspect the surrounding deck-drive system. A new PTO clutch can fail early if the belt is misrouted, a spindle is dragging, the idler is seized, or the wiring connector is damaged.
- Check the deck belt for glazing, cracks, fraying, or oil contamination
- Confirm the belt is routed correctly around the clutch pulley, idlers, and spindle pulleys
- Inspect idler pulleys and blade spindles for drag, grinding, or wobble
- Check battery voltage, PTO switch output, ground, fuse, and relay condition
- Inspect the clutch wiring connector for melting, corrosion, or loose terminals
- Inspect the crankshaft for rust, burrs, or keyway damage
- Confirm the anti-rotation bracket is installed correctly
Review the PTO clutch installation guide before replacing the clutch. If the old clutch will not slide off the crankshaft, read the PTO clutch stuck on crankshaft guide before forcing removal.
