Abstract/ Executive Summary:

Power tillers of different makers and models have been used for tillage operation in Bangladesh. Therefore, it was felt necessary to identify the suitable power tillers for tollage operation and make information available to the farmers. Six power tillers were studied under various tillage operation in the field and idling test in the laboratory of the Bangladesh Agricultural University, Mymensingh. The measurements were made to calculate the fuel consumption, effective field capacity, specific field capacity, specific fuel consumption and fuel consumption per unit volume of soil pulverized.The performance of those power tillers were compared. From comparison the performance of power tillers A (HUMAN-12), C (DONG FENG-12) and B (DONG FENG DF-12L) were found better and recommended for tillage operation in Bangladesh Condition.

Program Area: Farm Mechanization

Commodity: Power Tiller

Objectives:

To study the performance of six power tiller under different tillage operation for making information available to the farmers.

Methodology:

Six power tiller of different makes and models available in Bangladesh were used in the laboratory and field tests. The technical information of these power tillers were shown. In laboratory, full throttle idling test for each power tiller was conducted and test duration, engine speed, water oil, exhaust gas and ambient temperatures, fuel consumption, engine starting, engine noise, tilling depth adjustment, machine maneuverability and operations comfort were recorded. A tachometer, thermometer and stop watch were used in this study. Both at starting and end of each idling test the fuel consumption rate (litre/hr) was calculated. Performance tests were conducted on both concrete road and fallow land conditions in the Bangladesh Agricultural University Farm. On concrete road another power tiller was used for loading the trial power tiller and a mould board plough trailed with power tillers were used on fallow land conditions. A pull type dynamometer, tachometer, stop watch and measuring tape were used in this study. The forward speed, drawbar pull and fuel consumption for each test were recorded. A rotary tiller having 18 L-blades and a working width of 60 cm was used in rotary tilling and pudding on dry and wet land condition respectively for test plot size of 0.25 hectare in Bangladesh Agricultural University Farm. The tilling depth, fuel consumption and field capacity of each test were recorded.

Achievement/Findings:

One but all the power tillers under tests were found to be satisfactory regarding engine starting, engine speed, engine noise, water, oil and exhaust gas temperature, tilling depth adjustments, machine maneuverability and operators comfort etc. The performance of power tillers under idling and field tests were compared in different head such as; fuel consumption, specific consumption, fuel consumption per unit volume of soil pulverized and effective field capacity. From test results it was appeared that the tilling performance of power tiller A (HUMAN-12), C (DONG FENG-12) and B (DONG FENG DF-12L) were trailing close to it. Therefore, these three power tillers could be recommended for tilling operation in Bangladesh Condition.
