At the beginning of harvest we were running wheat concaves in red lentils and getting a clean sample with very few splits. After a few rains and some tough conditions it was hard to get rid of the splits so we pulled every second wire on the back 1/3rd of the concaves. This seemed to help but not eliminate cracking. One farmer told me to pull the wires on the front 1/3rd so the lentils could drop first, but this seemed backwards to me as I figured the untreshed pods would drop too early and I would be running a bunch of return or have too many pods in the tank. Any advice out there? This is 1st year running a New Holland. Always had red combines on the farm in the past. Have tried different rotor speeds and concaves setting also, but seems that when I drop speeds or open concave too much I just get more pods in the tank with same amount of splits so I just go back to the higher rotor speeds and narrower concave setting.
