A combine equipped with a floating cutterbar should be used to minimize header losses. Once in the combine, lentils thresh easily. Compared to wheat settings a slower cylinder speed is necessary to prevent cracking, and the concaves should be set wider. Initial wind and sieve settings for wheat may be used. It is best to let the seed dry down in the field, if the drier plant material can be handled by the combines without major losses due to shattering of the pods.
Natural air drying has advantages over heated air, but proper design of the system is necessary.
The design must ensure good airflow through the seed, which usually means that thinner layers of the seed must be used in this process. This is a direct reflection of the volatile nature of world prices for this commodity. With favorable prices, lentil has provided a very attractive alternative crop for good producers. Seed damage, presence of foreign material and high moisture content will reduce the grade of lentil and result in a lower price. As with other specialty crops, growers should always locate markets and delivery points and determine a suitable price before planting a new crop.
