Abstract

The transmission system of the combine cutting device was developed and manufactured from local material to be suitable for the harvesting operation under Egyptian conditions. Performance evaluation of the combine before and after development during the harvesting operation of rice crop was carried out in terms of grain losses, field capacity , field efficiency, fuel consumption, required power, energy, wearing rate, wearing resistance and cost requirements. The combine performance was studied as a function of change in combine forward speed and grain moisture content and operating time. The results were obtained to gave maximum field capacity, field efficiency, wearing resistance and minimum energy, power, fuel consumption wearing rate, and cost requirements for the two systems of the combine cutting device before and after development as following:
1- It is recommended to used the developed combine.
2- The combine  forward speed of about 3.5 km/h.
3- The grain moisture content about 23%.
