Two clutches for driving and PTO operation in one component. Both pressure plates are pressed against the facings by just one diaphragm spring. The clutches are released independently of one another with 3 release levers each.
Two-stage version: One clutch release bearing operates first the 3 levers for the drive clutch and then those for the PTO drive. The clutch pedal is pressed half-way to release the drive only and pressed fully to release both the drive and PTO clutches.
Independently operated version: the drive and PTO clutches are operated independently of each other by means of 2 clutch release bearings with two levers.
