This study explores the impact of tractor drawbar height (520, 530 and 540 mm from the ground) on key performance indicators, including pulling force, fuel consumption, pulling power and overall tractor efficiency. Present experiments were conducted on a special pulling power test track under controlled conditions at the Directorate of Agricultural Equipment and Machinery Test Centre of the Ministry of Agriculture and Forestry. Data were collected at different tractor forward speeds and performance parameters were modeled and optimized using Response Surface Methodology (RSM), a statistical approach widely used for multi-factor optimization. Present findings revealed that a drawbar height of 520 mm yielded the highest pulling force (47.4 kN) at a speed of 5.48 km h
