For most shoppers, the key question is simple: Can 124833 or 539124833 be replaced by 759-05064? In many compatible applications, yes. The replacement should still be confirmed by matching the original clutch number, clutch dimensions, rotation, wiring style, and mower platform.

Replacement Specs to Confirm

The 759-05064 replacement path is built around a 1-inch crankshaft bore and approximately 5.35-inch pulley diameter. These specs are critical because a clutch can look similar and still create belt alignment, engagement, or wiring problems if the core dimensions do not match.

  • Crankshaft Bore: 1 inch
  • Pulley Diameter: Approximately 5.35 inches
  • Rotation: CCW from pulley side
  • Operating Speed: Up to 3600 RPM
  • Design: Electric PTO clutch with electromagnetic coil
  • Common Use: Riding mowers, zero-turn mowers, commercial walk-behinds, and selected rear-engine platforms

Fitment warning: Do not order by part number alone if the mower has been modified, previously repaired, or fitted with a non-original clutch. Confirm the bore, pulley diameter, rotation, connector style, anti-rotation bracket position, and belt alignment before installing the replacement.

Warner and Ogura Number Clues

Many original electric PTO clutches were manufactured by Warner Electric or Ogura. The mower brand may list one part number while the clutch body itself shows a manufacturer number. Those stamped or printed manufacturer numbers can be valuable fitment clues.

Common Warner references

  • Warner 5215-18
  • Warner 5217-46
  • Warner 5219-series references in related but not always interchangeable clutch families

Common Ogura references

  • MA-GT-TRO
  • MAGTTRO
  • MA-GT-TROC
  • MAGTTROC
  • MA-GT-JD2
  • MAGTJD2
  • MA-GT-JD11
  • MAGTJD11
  • MA-GT-SN11

If your old clutch has a Warner or Ogura number, use it as a secondary clue, not the only fitment confirmation. The mower application, bore size, pulley diameter, rotation, connector style, and anti-rotation bracket still need to match.

Aftermarket Cross-Reference Numbers

Aftermarket suppliers may list this clutch family under several replacement numbers. These can help confirm that 124833, 539124833, 759-05064, 01008434, 44-0770, and 54-0220 are being treated within the same replacement ecosystem.

  • STENS: 255-210X, 255-336X, 255-348X, 255-349X, 255-350X, 255-940X
  • 8TEN: 810-CPT2303O
  • Xtreme / heavy-duty style references: commonly listed for 759-05064, 01008434, 124833, and related 54-0220 applications

Aftermarket numbering can vary by supplier. Always confirm the physical specs and application, not only the interchange list.

Do Not Confuse 124833 With Newer Toro PTO Clutches

This is the most important fitment warning on this page. The 124833, 539124833, 759-05064, 01008434, 44-0770, and 54-0220 family should not be confused with newer Toro and Exmark clutch families that may look similar in photos.

Toro 110-6766 is not the same clutch family

The Toro 110-6766 clutch is commonly associated with newer Toro TimeCutter, Titan, and related Exmark Quest applications. Although some versions may also use a 1-inch bore and CCW rotation, the pulley offset, deck alignment, connector style, and application family can be different.

Do not replace a 124833, 539124833, 44-0770, or 54-0220 clutch with a 110-6766 style clutch unless the original clutch number, pulley offset, wiring, and mower application confirm the match.

Toro 117-3869 is a different commercial clutch

The Toro 117-3869 commercial clutch family is not interchangeable with this 759-05064 / 01008434 replacement group. It may use a larger bore, larger pulley, different rotation, and higher torque rating depending on the application.

Compatibility alert: Searching only for “Toro PTO clutch” can lead to the wrong part. Match the exact OEM clutch number and physical specs before ordering.

Common Symptoms of a Failing 124833 or 539124833 PTO Clutch

If your mower uses the 124833 or 539124833 clutch family, replacement may be needed when the clutch can no longer engage or hold the mower deck under load.

  • Mower blades will not engage
  • PTO clutch clicks but blades do not spin
  • Deck belt does not move when the PTO is engaged
  • Blades engage, then slow down in thick grass
  • Clutch gets hot or smells burnt
  • Blade engagement becomes intermittent
  • Clutch works cold but fails hot
  • Clutch bearing is noisy, rough, or loose
  • Pulley wobbles or shows heat damage

If your mower blades will not engage at all, start with our PTO clutch won’t engage troubleshooting guide. If the clutch clicks but the blades do not spin, see the PTO clutch clicks but blades won’t spin guide. If the clutch gets hot or smells burnt, use our PTO clutch getting hot or smells burnt guide.

If there is no PTO click, the fuse keeps blowing, the connector is melted, or a new clutch will not engage after installation, use the PTO clutch wiring, fuse, and switch testing guide to test voltage, ground, fuse condition, switch output, relay function, safety interlocks, and clutch coil resistance.

Installation and Burnishing Note

After installing a new electric PTO clutch, follow the mower manufacturer’s service procedure. Many replacement clutches also benefit from a short burnishing process, which helps seat the friction surfaces before full-load mowing.

A common burnishing method is to run the engine at reduced throttle, engage the PTO for a short period, disengage it, and repeat several cycles before mowing under load. This helps the clutch surfaces mate evenly and can reduce early slipping or glazing. Always follow the instructions included with your replacement clutch when available.

Before installation, inspect belt routing, pulley alignment, wiring condition, deck spindles, idlers, and the anti-rotation bracket. A new clutch can fail early if the deck belt is misrouted, a spindle is dragging, or the connector is damaged.

How to Confirm the Correct Replacement

Before ordering the 759-05064 replacement for 124833 or 539124833, check the original clutch carefully.

  • Match the OEM number on the original clutch
  • Confirm the crankshaft bore is 1 inch
  • Measure the pulley diameter, approximately 5.35 inches
  • Confirm CCW rotation from pulley side
  • Compare the wiring connector or lead style
  • Check the anti-rotation bracket position
  • Confirm the mower model, serial number, and deck setup
  • Inspect belt routing and pulley alignment before installation

Not sure where to find the number? Use our PTO clutch fitment guide before ordering.
