List of top Agricultural Engineering and Technology Questions on Harvesting and Threshing Equipment

The output capacity and cleaning efficiency of a wheat thresher at an optimal operating condition are 600 \(\text{kg}\cdot\text{h}^{-1}\) and 99%, respectively. The grain-straw ratio of the crop is 2:1. If the grain recovery at main grain outlet is 100%, the throughput capacity will be
During testing of a thresher, 100 N.m is recorded at 600 rpm at the main shaft of threshing cylinder. The diameter of threshing cylinder is 140 mm. The cylinder is operated by a V-belt and unit mass of v-belt is 1.0 \(\text{kg}\cdot\text{m}^{-1}\). What will be the maximum tension in the v-belt at the condition of maximum power transmission?
