General Platform Information The MidWest Crophawk Platform consists of 9 main components: Frame Removable Components Reel Feed Drum Drive system Knife. Adaptor Draper Belts Hydraulics / Electrics Frame The frame is the base structure that all operating components are attached to. This single piece...
Page 13
General Platform Information 3. Reel The MidWest platform has two types of reels driven from the combine’s own hydraulics system. Pick-up reel (Pictured) is a poly finger, six bar, single barrel unit to 10m (33’) with all sizes above 10m (33’) being twin barrel reel.
Page 14
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.
Page 15
General Platform Information 8. Draper Belts. The MidWest platform operates two types of Draper belts. The outer Draper belts conveys the crop to the centre feed belt . The outer draper belts are 915 mm wide and have a V form guide moulded to the centre of the belt.
