Overview
This page covers an aftermarket replacement PTO clutch for select Scag commercial mower applications using the Scag 461826 / 461662 and Ogura GT5-MC03 / GT5MC03 clutch path.
The purchase button on this page links to a third-party aftermarket replacement sold on eBay. It is not presented as a genuine Scag OEM or genuine Ogura clutch unless the linked seller listing specifically states otherwise.

Common applications include select Scag Turf Tiger, Turf Tiger II, and Cheetah configurations using the GT5 clutch path. Scag also used smaller GT3.5 clutches on similar mower families, so do not order by mower series, deck size, or appearance alone.
Match the original PTO clutch number before ordering. If your clutch is marked Scag 461662, Scag 461826, or Ogura GT5-MC03 / GT5MC03, this is the correct replacement path.

Replaces OEM Part Numbers
- Scag: 461662
- Scag: 461826
Scag 461662 supersedes to Scag 461826 in the confirmed OEM replacement path.
Aftermarket & Manufacturer Cross-Reference Numbers
- Ogura: GT5-MC03
- Ogura: GT5MC03
- Xtreme: X0815
Xtreme also lists X0815 as a replacement for Ogura GT5-MC04D / GT5MC04D. Ogura identifies GT5-MC04D as a separate diesel-engine-type GT5 configuration, so GT5-MC03 and GT5-MC04D should not be treated as the exact same original Ogura clutch model.
Important Fitment Check
Match the original PTO clutch number before ordering. This replacement is intended for the Scag 461662 / 461826 and Ogura GT5-MC03 / GT5MC03 clutch path.
Do not substitute this clutch for the smaller Scag 461661 / Ogura GT3.5 clutch based on mower appearance or deck size alone.
Do Not Confuse With Scag 461661 / Ogura GT3.5
Scag 461661 is a separate PTO clutch path associated with the smaller Ogura GT3.5 clutch family.
Confirmed GT3.5 paths include select:
- Scag Turf Tiger STT52V-27CH applications
- Scag Turf Tiger STT-29DFI-SS applications
- Scag Cheetah SCZ61V-31FX applications
- Scag Cheetah SCZ61V-32CV applications
Do not substitute 461826 / GT5 for 461661 / GT3.5 unless the exact mower parts diagram and physical clutch specifications confirm the change.
Scag Turf Tiger II Fitment Note
Scag Turf Tiger II applications can use different PTO clutch families depending on the engine configuration.
Select Briggs-powered Turf Tiger II configurations are associated with the Ogura GT5 clutch family, including model paths such as:
- STTII-61V-33BV
- STTII-61V-40BV-EFI
- STTII-72V-40BV-EFI
Other Turf Tiger II configurations may use the GT3.5 clutch family. Confirm the original clutch number before ordering.
Scag Cheetah Fitment Note
Do not assume every Scag Cheetah uses the same PTO clutch.
Confirmed legacy Cheetah diagram paths show:
- 61V configurations: commonly associated with the 461661 / GT3.5 clutch path
- 72V configurations: select applications associated with the 461826 / GT5 clutch path
Current Scag Cheetah II specifications use the Ogura GT5 blade-engagement clutch family, but the exact OEM part number should still be confirmed for the individual mower.
Does This Fit Scag Tiger Cat II?
Do not use this clutch as a general Tiger Cat II replacement.
Current Scag Tiger Cat II specifications use the Ogura GT3.5 clutch family rather than the GT5 family. Confirm the exact OEM clutch number before following any marketplace listing that claims broad Tiger Cat II compatibility.

- Do not assume every Turf Tiger or Turf Tiger II uses GT5
- Do not assume every Cheetah uses GT5
