520			_aIn the absence of appropriate mechanization, harvesting of both rice and wheat crop is a major production problem in Egyptian delta. Acute labor shortages at harvest time cause delays in clear fields leading to high grain and straw losses. This work describes the constructions of a new self-propelled machine for cutting rice and wheat crops. The machine consists of four main devices names: cutter bar, crop reel, conveyor belt and transmission system. The new constructed machine was operated in rice and wheat fields at four kinematic parameters and four grain moisture contents to determine the proper operating parameters for cutting both rice and wheat crop. Results indicated that the maximum field capacity and the lowest operating cost of (0.452, 0.621 fed/h), (37.50, 37.26 L.E/fed) were obtained at low kinematic parameters of (1.8, 1.45) and low grain moisture content of (21.45, 19.11 %); maximum both field efficiency and cutting efficiency of (69.17, 82.15 %), (86.88, 91.41 %) were obtained at high kinematic parameters of (4.67, 3.20) and low grain moisture content of (21.45, 19.11 %); minimum fuel and energy consumed of (1.51, 0.47 l/h), (2.97, 1.53 kW.h/fed) were obtained at kinematic parameters of (2.33, 1.78) and grain moisture content of (22.20, 20.10 %) and minimum grain losses and criterion cost of (1.03, 0.76 %), (72.18, 64.82 L.E/fed) were obtained at kinematic parameters of (2.33, 1.78) and grain moisture content of (22.20, 20.10 %) for both rice and wheat crop, respectively.
