FLUID ACTUATED CLUTCH HAVING FLUID SLIP FITTING SAFETY INTERLOCK Abstract of the Disclosure A main drive for crop cutting, conveying and/or processing components of a self-propelled harvester includes an input shaft which extends crosswise to and is coupled for being driven by a longitudinally extending engine output shaft. The input shaft carries a spring-released, hydraulically-engageable disc clutch, which, when engaged, transfers power from the clutch to a multi- grooved belt drive sheave which is coupled to respective driven sheaves of the crop cutting, conveying and/or processing components by a drive belt. The clutch is mounted on the shaft outboard of the drive sheave and the shaft is provided with a fluid passage that extends inwardly from its outboard end and is coupled in fluid communication with the clutch piston. A slip fitting is releasably coupled to the outboard end of the shaft and is adapted for being coupled to a conduit for conveying fluid to or returning fluid from the clutch piston. The shaft includes splined outboard section located between the fitting and the clutch which is adapted for receiving a dynamometer drive element, once the slip fitting is removed, so that the engine output may be checked without any danger of inadvertent clutch engagement.
