The field experiment was carried out at college farm to evaluate the performance of tractor drawn rotavator. Based on observations, the soil bulk density after tillage treatment by rotavator (T1) was found 1.299 g/cm3 which was much lower than that after tillage treatment by harrow (T2) 1.330 g/cm3 and by cultivator (T3) 1.314 g/cm3, the soil moisture value was found to be 23.10 g per 100 g before tillage and 23.24 g per 100 g after tillage operations which shows soil moisture content did not differ significantly between treatments, the rotavator improved soil tilth which was evaluated by measuring the MMD of soil clods. The MMD (mean mass diameter) of soil clods in tillage treatments by rotavator (T1) was 14.77 mm. MMD was found significantly larger for harrow (T2) 17.30 mm and for cultivator (T3) 23.57 mm, the operational time was higher by 247.2% and 147.2% in the case of T2 and T3 and the diesel consumption was higher by 103.2% and 31.9% in case of T2 and T3.
