Segmented Hex-Shaft cutterbar

The modular cutterbar is driven by segmented hex shafts and pinion gears.  This design allows for quick disassembly of individual modules, rather than the entire cutterbed, for ease of servicing and repair.  Each module has its own lubrication so the cutterbar can be operated on steep angles for extended periods of time without grease or oil running to one end. Under each module, is a replaceable skid shoe that protects the cutterbar itself from wear caused by running on the ground. Each disc is mounted to a vertical shaft and features a shear point.  In the event an obstruction is encountered, the shaft will shear protecting the more expensive gears inside the module reducing overall maintenance and repair costs.
