Slip clutches on forage harvesters: which friction plates fit where?
Finding the correct friction plates for a slip clutch can be confusing. This guide covers the most common slip clutches and friction plates used on forage harvester attachments.
1. Kemper maize headers
Most slip clutches are found in the attachment. A Kemper maize header, for example, has a central slip clutch underneath the middle of the header to protect the entire assembly from overload.
Two versions are used, both supplied by Walterscheid and produced specifically for Kemper:
- Water-cooled: Identified by the large cooling-water tank in the centre of the clutch.
- Standard: Without a water tank.

- Large drums: four plates per drum.
- Small drums: two plates per drum.
- Part number: 59046.
3. CLAAS PU300HD grass pick-up
The CLAAS PU300HD grass pick-up uses a different arrangement:
- Upper auger: A large slip clutch with four friction plates, type 59046.
- Lower output shaft: Type 57911, on both sides of the gear.
