| 520 | _aThe aim of this investigation was to find out the optimum tractor power requirement under Libyan agricultural conditions in order to suggest the most suitable tractor power for the majority of Libyan farmers. In addition to the economic analysis of the different tractors and elements when executing agricultural operations. A comparison was carried out between two tractor power level, 47HP and 75HP. The tested parameters were drawbar pull, slip percentage, fuel consumption, and maneuverability. The lowest wheel slip percentage was recorded with tractor 47HP when operating all implements except with the chisel plough 2nd pass. Also it was clear that, there was significance different between the mechanical elements with different types of power that the lowest wheel slip percent was obtained by chisel plough 1st pass and land leveler. It was clear that the tractor 75HP when currying different equipment, that the fuel consumption l/h was higher than the tractor 47 HP. The actual field capacity of tractor 75HP was significantly higher than the tractor 47HP with different implements | ||
