2. Turn the straw walker to its lowest position and mark the side of the combine harvester (position A in Figure 9) at a right angle to the cable
fastener.
Figure 8: Straw walker mark angle
3. Turn the straw walker to the highest position and mark the side of the combine harvester (B).
4. To determine the length of cable needed to make the loop, measure the distance (L) between marks (A) and (B) and multiply by three.
Figure 9: Straw walker loop length calculation
5. Make a loop of from the calculated length of cable and attach the cable fastener 20 mm under the lower mark.
6. Repeat for both walker pads.
7. Connect the cables to the junction box, avoiding any sharp edges, pinch points or other sources of cable damage, and fasten to the
combine harvester using supplied cable ties.
8. Connect the cables to the circuit board as shown in Figure 2.
Fitting the sieve sensor
Position
The sieve sensor must be fitted so it can measure the grain loss behind the sieves across the entire width of the sieves. The best sieve
sensor position for normal grain types is 120 mm behind the rear edge of the sieves and 50 mm under the sieves (measured from the centre
of the tube).
Figure 10: Sieve sensor bracket placement
The supplied brackets have three slits. When fitting, measure from the middle slit to allow the sensor to be moved depending on crop type.
For example, the sensor can be moved closer when harvesting a crop where little air is blown under the sieves, such as oilseed rape, or the
sensor can be moved further away when harvesting a crop that requires more air to be blown under the sieves.
