3. Reel
The MidWest platform has two types of reels driven from
the combine’s own hydraulics system.
1. 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.
2. The Bat reel is a five slat configuration
manufactured from high tensile galvanised material
in single barrel units up to 10m (33’) with all sizes
above 10m (33’) being twin barrel reel.
4. Feed Drum
The MidWest feed drum is a mechanically driven 406mm
(16 in) diameter feed drum that has 19 to 21 retractable
fingers with 150 mm (5.9 in) of travel, and is protected by a
bi-directional torque clutch, accommodating combine feed-
er reverse. The Drum has 70 mm (2.7in) of vertical travel
and can be adjusted 60 mm (2.3 in) fore and aft.
5. Drive system
The MidWest platform drive system relates to all mechani-
cal driven components. Power input is from the combine’s
feeder house output shaft via a PTO shaft to the platform’s
drive box (pictured). Within the drive box, power is trans-
ferred via a 90mm (A) belt to drive the feed drum (B) and
knife drive (C.) shafts. The feed drum drive is protected by
a bi-directional torque clutch and power to the feed drum
is via a PTO shaft. The knife drive shafts are protected by
an adjustable slip clutch (D) within the drive box and power
to the epicyclical knife drives is via a 37mm belt.

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.

CropHawk Draper Platform Operators Manual 15
General Platform Information
8. Draper Belts.
The MidWest platform operates two types of Draper belts.
1. 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. This design ensures true
alignment and allows for the belt to be reversed.
The belt is driven hydraulically via a vulcanised
drive roller and is tensioned by the inner idler roller.
2. The centre feed belt conveys the crop to the feed drum, which
delivers the crop to the combine. The centre belt is 1500 mm wide
and has a V form guide moulded to the left hand side of the belt. The
belt is driven hydraulically via a steel drive roller and is tensioned by
the front idler roller.
9. Hydraulics / Electrics
The MidWest platform contains two separate hydraulic systems.
1. The self contained, fully integrated hydraulic system drives the draper belts.
The feeder house drive shaft from the combine is connected to an input
drive shaft on the platform via a PTO shaft. The accelerator gearbox is
mounted on the input shaft and drives the hydraulic pump. The draper con-
trol circuit is split between the lateral drapers and the centre draper. The belt
speeds are independently controlled by a dual flow control incorporating a
relief valve. The oil is filtered then returned to the reservoir tank.
2. Dependant on the combine ‘s hydraulic system is the reel
drive and reel cylinders. This system operates from the
combines hydraulics allowing full in cab control.
Electrics
The electrical system and sensors are integrated into the
combines operating system, and include reel speed control,
lighting and allowing for full platform recognition by the combine.
