A Study on fuel consumption and work performance of different tractors with tillage implements

A study was conducted to evaluate fuel consumption and work performance with disc harrow and cultivator In sandy loam soil. Three soil cover conditions viz. unploughed soil, stubble soli and tilled irrigated soil surface were taken to determine the better performance of tractor-implement system and fuel economy. Three tractors were used of 55, 35 and 30 bhp, at three speed control setting of the tractors, viz. 1/3^rd, 2/3^rd and full throttle positions. The disc and cultivator combination were found most economical to be operated 2/3^rd speed control position. Maximum fuel consumed 4.1 l/h in tilled irrigated soil with cultivator and disc harrow 3.6 l/h at 2/3^rd throttle position because of Increased depth of operation. Almost in all soil cover conditions, cultivator gave maximum field capacity. Fuel consumption for cultivator was higher than disc harrow due to higher depth of ploughing.
