Abstract:
A field experiment was conducted at dry and wet field conditions of Chhattisgarh. Fuel economy and tractive performance of three different tractors models was determined at part loads with commonly used tillage implements with influence of dry and wet field conditions. A field testing of seven tractor-implement systems for dry field conditions viz. tractor-zero till ferti seed drill, tractor-MB Plough, tractor-disc harrow, tractor-seed drill, tractor-rotavator, tractor-cultivator and tractor-subsoiler and for wet field conditions viz. tractor-rotavator and tractor- cultivator was carried out at eight different throttle positions (0%, 25%, 50%, 60%, 75%, 85%, 90% and 100%). Gear was selected at constant condition at low-IInd. Three tractor models with their power rating 55 hp (T₁), 57 hp (T₂) and 63 hp (T₃) were used for experimentations under actual field conditions. Fuel consumption, field capacity, width and depth of cut of implements were measured at different part loads for different implements. In dry field conditions, the following throttle positions are recommended for optimal performance with various tractor attachments. A Tractor 2^nd (57 hp) equipped with a zero till ferti-seed drill attachment should be set to 85% throttle for peak performance. When using a Tractor 2^nd (57 hp) with an M.B. plough attachment, it's best to operate it at 50% throttle for ideal results. For a Tractor 1^st (55 hp) with a disc harrow attachment, maintaining a throttle position of 50% is recommended for optimal operation. When using a Tractor 1^st (55 hp) with a seed drill attachment, it's advisable to set the throttle at 75% for the best performance. Similarly, if you have a Tractor 1^st (55 hp) with a rotavator attachment, it should be operated at 50% throttle to achieve the most efficient performance. When using a Tractor 1^st (55 hp) with a cultivator attachment, it's recommended to set the throttle at 75% for optimal conditions. Finally, if you're using a Tractor 1^st (55 hp) with a subsoiler attachment, operating it at 100% throttle provides the best conditions for field performance in dry soil. In wet field conditions, it is recommended to operate Tractor 3^rd (63 hp) with a rotavator attachment at 60% throttle for optimal field performance. Likewise, when using Tractor 3^rd (63 hp) with a cultivator attachment, setting the throttle to 75% is advised for achieving the best possible conditions during field operations.
