Fitting the cylinder with filler plates was found to have a positive effect on wheat grain separation through the concave and also to reduce grain damage .
The hypothesis in the present research was that covering the spaces between the cylinder rasp bars has a positive effect on corn grain damage during threshing (the percentage of damaged grain decreases) and on grain separation through the concave (the percentage of threshed grains passed onto the straw walkers decreases).
Beaters had significant effect on field emergence (FE) only in Experiment I, while beaters and concaves had no significant effects on all investigated traits in both Experiment I and II (Table 5).

We have been working to improve the concaves to reduce the number of rows in order to lower downtime," Papjewski said.
We have mechanical fasteners that hold concaves to the top shell," Novak said.
Because they are electronically controlled from the cab, the concaves can be quickly adjusted between crops.
Concaves with 6 mm slots are factory installed as standard.
