Abstract:

A cutting and mowing apparatus comprising a continuous sickle chain assembly (8) utilizing cutting knives (10). The sickle chain assembly is confined within channel (29) formed by stationary guards (28) by means of alternating chain members (12), knives (10), and links (14). The sickle chain assembly is motivated by drive assemblies (31), which possess an integral protective slip clutch assembly (45). The sickle chain assemblies tightness is maintained using spring loaded tensioner assemblies (89). On the rearward return path, the sickle chain assembly slides in the return channel (144). The drive assemblies (31) are powered from the hydraulic system of the parent machine, such as a combine, tractor, or mower/conditioner. This unit, while being designed to retrofit existing cutting machines, can also be used for new production models.
