The Ferris IS5000Z/C31D diesel zero-turn mower uses a heavy-duty commercial electric PTO clutch that is much larger and more expensive than a standard residential mower clutch.
For early IS5000Z/C31D machines, including low serial-number units, the correct replacement path is:
- Ferris 22884
- Ferris 5022884
- Ferris 5100040
- Current Briggs & Stratton / Ferris part number: 84009156
- Warner cross-reference: 5227-5
Ferris IS5000Z/C31D Clutch Fitment
This application uses a heavy-duty double-pulley PTO clutch with a 1-1/4-inch crankshaft bore. It is commonly associated with the Warner 5227-5 commercial clutch family.
Known measurements for this application include:
- Crankshaft bore: 1-1/4"
- Clutch depth: approximately 4"
- Double-pulley diameter: approximately 4-3/4"
- Application: Ferris IS5000Z/C31D diesel zero-turn mower
Fitment warning: Do not select a replacement based only on bore size and pulley diameter. This mower requires the correct torque capacity, pulley spacing, connector, anti-rotation bracket, clutch height, and mounting geometry.
Which Part Number Should You Search?
The best current number to search is 84009156.
You may also find older listings under:
- 5100040
- 5022884
- 22884
- Warner 5227-5
Older Warner 5227-5 listings may be priced significantly higher because of limited remaining stock. The current Briggs & Stratton / Ferris number, 84009156, is generally the cleaner replacement path.

Why Is This Ferris PTO Clutch So Expensive?
The Ferris IS5000Z/C31D is a large commercial diesel zero-turn mower. Its PTO clutch is built for a higher-capacity deck-drive system than the clutches used on most residential and light-commercial mowers.
The higher price is influenced by:
- Heavy-duty commercial torque capacity
- Large 1-1/4-inch crankshaft bore
- Specialized double-pulley design
- Limited production and replacement availability
- Old-stock pricing on discontinued Warner-numbered units
This is why a generic double-pulley clutch should not be substituted based only on similar measurements.
How to Confirm Fitment Before Ordering
Before purchasing any replacement clutch, confirm the following:
- Full mower model number
- Complete mower serial number
- Deck size
- Crankshaft diameter
- Upper and lower pulley diameters
- Pulley spacing
- Overall clutch height
- Electrical connector shape
- Anti-rotation bracket location
- Keyway and mounting-bolt arrangement
Clear photos of the clutch from the top, bottom, side, pulley, connector, bracket, and crankshaft area can help prevent ordering the wrong unit.
