Power balance for some different types of tractors used in Iraq [electronic resource].

Includes references.

The aim of present study was to determine the most suitable tractor to complete the implementation of the basic agricultural operations through technological time in the agricultural production conditions in Iraq. Afield experiment was conducted at the Faculty of Agriculture, Baghdad University during 2011, to evaluate the performance and power requirements for these tractors. To achieve this goal 3 tractors of different powers ranging from 70-105 HP were used to execute the commonly mechanized operation in Iraq. Three different operations were used: ploughing with mouldboard plough, harrowing with disc. harrow and land levelling by land leveller. The optimum tractor power requirement under Iraqi agricultural conditions was selected according to the evaluation of the following criteria: the performance, and tractor power balance for these tractors, Therefore it might be suggested from the results of this investigation covering many technical aspects that the engine horsepower required for executing must of the main Iraqi agricultural operations. To select the New Holland tractor (80HP) for carrying ploughing and harrowing operations and to select Tumosan tractor(105 HPJ for carrying levelling operation.
