Abstract

Minimize of all harvest losses for wheat crop represent the important factor for upgrade harvest system The present study aimed to evaluate a locally combine for harvest wheat crop The experiments were carried out in Barkeen Village – Dakahlia Governorate during two seasons (2008 – 2009) for harvesting wheat crop (Sakha 93) at forward speed of 0.53, 0.70, 0.95 and 1.15 km/h, and at grain moisture contents of 16.73, 14.41 and 12.13 % during standard drum speed of 24.74 m/s. The pre-harvesting losses for (sakha 93) w as about 0.28% at grain moisture content of 12.13% , straw moisture content of 25.73% and daily times of 12^PM.While,the highest value of total grain losses 2.08 % was obtained at forward speed of 1.15 km/h and grain moisture content of 16.73 %.The highest performance efficiency of machine 98.91% was obtained at forward speed of 0.53 km/h and grain moisture content of 12.13 % While, the highest cutting efficiency 94.81 % were obtained at forward speed of 0.53 km/h and grain moisture content of 12.13 %.The highest effective field capacity and efficiency (0.48 fed;/h and 78.38%) were obtained at forward speed of (1.15 and 0.53 km/h) and grain moisture content of 12.13 %, respectively. Whereas .the lowest value of energy requirements 311.01 kW.h/fed; was at forward speed af 1.15 km/h and grain moisture content af 12.13%, respectively. The lowest value of criterion cost 312.10 L.E / fed; were obtained at forward speed of 1.15 km/h and grain moisture content of 12.13% .
