126-8926 and Warner 5219-205 Cross-Reference

The cleanest way to understand this replacement path is:

Replacement Specs to Confirm

This is a heavier-duty clutch path than many residential PTO clutches. Before ordering, compare your original clutch to these core specs:

Crankshaft Bore: 1-1/8 inch
Pulley Diameter: approximately 7.20 inches
Torque Rating: approximately 125–130 ft-lbs
Design: electric PTO clutch with electromagnetic coil and integrated brake
Common Application Type: commercial / heavy-duty zero-turn platforms

A clutch can look similar and still be wrong. Confirm the bore size, pulley diameter, pulley offset, wiring connector, lead length, anti-rotation bracket position, and deck belt alignment before installing the replacement.

Common Compatible Mower Platforms

The 126-8926 / Warner 5219-205 clutch family is commonly associated with select Exmark Radius and Toro Titan HD models. Application can vary by deck size, engine package, serial range, and previous repairs, so always confirm by the original clutch number.

Exmark Radius

Exmark Radius E-Series
Exmark Radius S-Series
Exmark Radius X-Series
Common deck sizes include 48-inch, 52-inch, and 60-inch configurations

Toro Titan HD

Toro Titan HD 2000 Series (select models)
Toro Titan HD 2500 Series (select models)
Commonly associated with certain 60-inch tube-frame applications (examples include 74463, 74472, 78472 — always verify)

If your mower is one of these platforms and the original clutch number matches the 126-8926 / Warner 5219-205 family, shop the 126-8926 PTO clutch replacement.

OEM and Manufacturer Numbers in This Family

Use these numbers when checking the original clutch, parts diagram, service paperwork, or aftermarket interchange listings:

126-8926
126-4324
Warner 5219-205

If your original clutch has a Warner number, treat it as a helpful clue, but still confirm the mower model, bore size, pulley diameter, pulley offset, connector style, and bracket position.

Important: Do Not Confuse 126-8926 With 126-8925

Exmark and Toro use more than one Radius / Titan HD clutch path.

126-8926 / Warner 5219-205 is the larger-bore path (typically 1-1/8 inch).

126-8925 / Warner 5219-204 is a different path that is commonly listed as a 1-inch bore clutch on certain specific Radius serial ranges.

Ordering the wrong bore results in a non-fitting clutch. Always match the number stamped on the original clutch or the official parts diagram.

Do Not Confuse 126-8926 With Other Toro / Exmark Clutches

Toro and Exmark use multiple PTO clutch families across TimeCutter, Titan, Titan HD, Radius, Quest, Z Master, and other platforms. Do not order by brand name alone.

126-8926 is not the same as every Titan or Radius clutch. Many residential TimeCutter and standard Titan models use completely 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 belong to a different 1-inch bore, approximately 5.35-inch pulley clutch group. 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, Exmark Quest, and related applications with different fitment requirements. If your original clutch shows 110-6766 or related 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
Blown fuse or electrical issue when PTO is activated

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.

Match the OEM number: Look for 126-8926, 126-4324, Warner 5219-205, or Warner 5219-201.
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.
