Description: Wild rice is grown in waterbodies across northern Saskatchewan and is har vested by air-driven boats equipped with grain-collecting pans which dis lodge the easily shattered kernels. The design of the harvesters is dis cussed and airflow characteristics measured. Wind speeds in excess of 100 km/h were recorded behind a harvester. During turning manoeuvres the air is directed laterally into unharvested rice by the rudders and some grain loss occurs. Grain losses from wind blast during static trials was measuredat 3.7%, while under normal operating procedures losses ranged from 4.7% adjacent to the hull to 1.2% at distances of 2.5 m.
