Abstract :Tractor performance tests conducted under laboratory test conditions are important because these tests determine the performance characteristics used to compare strengths and weaknesses of tractors. The objective of this study was to determine the effect of diesel fuel insert ignore into journalissuearticles values(B0); and 3 different biodiesel blends made of canola oil insert ignore into journalissuearticles values(B10, B20, B30); on tractor power take-off insert ignore into journalissuearticles values(PTO); performance characteristics. Performance characteristics studied were PTO power, engine torque, engine fuel consumption, and specific fuel consumption on an agricultural tractor insert ignore into journalissuearticles values(Massey Ferguson 3056 2WD); at the test laboratory of the Directorate of Agricultural Machinery Test Center insert ignore into journalissuearticles values(TAMTEST);, Ministry of Agriculture and Rural Affairs, Ankara, Turkey. The maximum PTO power insert ignore into journalissuearticles values(32.35 ± 0.06 kW);, the minimum specific fuel consumption insert ignore into journalissuearticles values(288.72 ± 0.11 g Kw-1 h-1);, and the minimum fuel consumption insert ignore into journalissuearticles values(11.08 ± 0.13 L h-1); were achieved by using B20 at an engine speed of 2100 min-1. The nominal engine speed for petrodiesel was 2200 min-1, whereas the greatest engine power was accomplished at 2100 min-1 for all biodiesel blends. Even though 2%-4% reduction was obtained in fuel consumption by using biodiesel blends at 2100 min-1, the mean fuel consumption was statistically insignificant insert ignore into journalissuearticles values(P > 0.05);, whereas average fuel consumption was higher with petrodiesel at 2200 min-1 insert ignore into journalissuearticles values(P < 0.05);. It was concluded that B20 insert ignore into journalissuearticles values(20% biodiesel + 80% petrodiesel); could be a more efficient alternative to petrodiesel fuel.
