Abstract
comparing the performance of yanmar and claas combines during harvesting different rice varieties in terms of total grain losses, field capacity and efficiency, fuel and energy consumed and total cost requirements.selecting the optimum harvesting parameters such as combine forward speed, grain moisture content during haring harvesting operations. wstimating energy consumed and total harvesting cost using two combine harvesters in each rice varieties.
