N2 - The aim of this study is to analyze the power requirement of a 78 kW agricultural tractor for the optimal design of a power transmission system. Moldboard plow tillage, disc plow tillage, rotary tillage, baler operation and loader operation are selected as major agricultural operations. The power measurement system is constructed for the driving axle, PTO axle, main hydraulic pump and auxiliary hydraulic pump. The total power requirement for the moldboard plow tillage, disc plow tillage, rotary tillage, baler operation and loader operation are 53.69, 37.50, 65.61, 36.84 and 17.55 kW, respectively. The rotary tillage consumed about 84 % of the engine rated power, with the highest required power compared to other agricultural operations. The power requirement of the driving axle, PTO axle, main hydraulic pump and auxiliary hydraulic pump are 13.6, 31.5, 2.01 and 1.84 kW, respectively. The sum of the power requirements is 48.9 kW, which is 63 % of the engine rated power.
