Overview
If you are comparing 917-04552A, 917-05209, and 917-05001, you are likely working on a Cub Cadet, MTD, Troy-Bilt, Craftsman, or related mower platform that uses an electric PTO clutch to engage the mower deck.
These part numbers are commonly searched together because they are all MTD-family PTO clutch numbers, but they should not be treated as automatically interchangeable. The correct replacement depends on the original clutch number, mower model, connector style, pulley setup, crankshaft bore, rotation, and deck belt path.

Important Fitment Check
Do not order a PTO clutch by appearance alone. Many electric PTO clutches look similar but differ in connector style, pulley offset, anti-rotation setup, pulley width, belt path, and deck application.
Before ordering, match the original clutch number first. Then confirm:
- Crankshaft bore size
- Pulley diameter
- Rotation direction
- Connector style
- Anti-rotation bracket or tab setup
- Mower model and deck size
- Deck belt path
- Serial number range if your mower has multiple PTO clutch options

FAQ
Are 917-04552A, 917-05209, and 917-05001 interchangeable?
Do not assume they are interchangeable. These are separate MTD-family PTO clutch routes with different model applications and cross-reference paths. Match your original clutch number first before ordering.
What is the safest way to confirm the correct PTO clutch?
Match the number stamped on your original PTO clutch. Then confirm bore size, pulley diameter, connector style, rotation, anti-rotation setup, mower model, deck size, and belt path.
Can I order by mower model only?
Mower model is helpful, but it should not be the only confirmation point. Some mower families used more than one PTO clutch depending on deck size, production range, engine setup, or belt configuration.
Where can I buy these PTO clutch replacements?
You can shop the three replacement paths here: 917-04552A, 917-05209, and 917-05001.
