- 27 - Table Auger (Fig. 20) height and finger positions are adjustable Adjust the table auger vertically to suit the lot of straw in the crop being threshed. E.g. in strong rye and turnip rape adjust the clearance between auger and cutting table wider, approx. 30 to 40 mm. To adjust, loosen screws A on both ends of cutting table and the table auger can be lifted or lowered as required. Clearance between table auger and bottom has to be the same on both ends of the table. The normal clearance is 15 mm. After moving table auger, check feed finger adjustment and drive belt tension. Feed finger position is adjusted, when screw E has been loosened, with lever B on the right and end of the cutting table. Minimum acceptable clearance between the bottom and finger tips is 10mm. Crop Elevator Chain (Fig. 21) correct height and tension The elevator has a fixed top roller and a floating bottom roller to enable the elevator to smooth out the flow of crop to the cylinder and to handle a fluctuating feed. Adjust the clearance between the bottom roller and the bottom of the elevator housing by the screws C. Correctly adjusted, there should be a clearance of 0 to 5 mm between the lowest slats and the housing. The elevator chain is adjusted with screws D. Check the tension through the inspection door in the top of the elevator housing. The tension is correct when the deflection midway between the top and bottom rollers is approx. 50 mm. The bottom of the crop elevator can be adjusted depending of the crop harvested. For cereal and small seed it is kept in upper position for good cleaning. For corn it can be lowered to avoid grain damaging. |
