ABSTRACT:
A forage harvester of the type having a rotary reel cutterhead and a feed roll mechanism for feeding crops to the cutterhead is provided with improved drive means for the feed roll mechanism including a forward chain drive arrangement incorporating intermediate shafts and an electromagnetic clutch and a reverse chain drive arrangement incorporating a second electromagnetic clutch, both drive arrangements being driven from the cutterhead drive and driving a common output shaft operatively connected with the feed roll mechanism. An electrical remote control switch operates the electromagnetic clutches for mutually exclusive engagement, or with neither clutch engaged, to produce remotely controlled shifting of the mechanism between forward, idle and reverse drives.
