Abstract

Improvements in harvesters of the type comprising a mowing device, a cutting drum and a feeding system for feeding the forage cut by the mowing device to the cutting drum, the feeding system being reversible to eliminate blockages, characterized in that the the feeding system (23) is driven by a reversible transmission system including a first transmission shaft (27) mounted on one end of an articulated arm (28) pivoting about an axis coincident with a second transmission shaft ( 30) connected, in motor form, to the first transmission shaft, which comprises a first pulley (26) on which a transmission belt (25) passes which connects it to a second pulley (24) mounted to rotate with a shaft motor (22) by means of which the transmission system is driven, the articulated arm (28) being maintained in a first position separated from the drive shaft (22), through means of elastic influence (51), under normal operating conditions, so that the transmission belt (25) remains in tension, there being control means operable to rotate said arm (20) from said first position so that said end of the arm (28) approaches the drive shaft in order to produce a loosening in the tension of the transmission belt (25) and effect the clutch between a first gear (42), carried by said first transmission shaft (27) and a second gear wheel (38), behaved by the aforementioned: drive shaft (22), with which the direction of rotation of said first transmission shaft (27) is reversed to effect the reversal of the feed system (23).
