General Platform Information
6. Knife.
The
MidWest
platform uses a synchronised (timed) dual knife system with twin epi-
cyclical grease lubricated knife drives. Driven by 37mm carbon cog belts drive en-
suring positive cutting power is maintained at all times. A clutch provides pro-
tection without affecting knife timing. This system is fitted to all mechanical driven
platforms.
7. Adaptor.
The
MidWest
adaptor attaches the platform to the feeder housing of the combine and is unique to the model and
series of combine. The adaptor comprises two separate floatation systems for both vertical and lateral movement. The
vertical float system is suspended by 2 air bags linked via a tank enabling 100mm vertical travel with the ride being
controlled by adjustments to air bag pressure. The lateral floatation system supports the entire platform weight on a
central pivot point and is suspended horizontally to the combine harvester. This unique ‘hover point’ patented suspen-
sion system allows the platform to mount closer to the combine allowing better visibility and decreasing stress on the
combine feeder house.
