Simultaneous comparison of the effects of shaft load and shaft positions on tractor OEE in two soil conditions (cultivated and uncultivated)
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 3
Abstract
one of the main indexes of energy consumption in tillage is overall energy efficiency of tractor. To measure this factor exactly and simultaneously with the other factors affecting it, at first MF 399 tractor was equipped with different kinds of sensors and a data collection system, so factors such as energy consumption, rear wheel slip percentage and overall energy efficiency of tractor during disking, with the data collection speed of 1000 data per second were measured and the data were sent through wireless to a computer 1.5 kilometers away and at the same time stored in excel format. The factorial design was accomplished three times and included factors such as: land condition (cultivated T and uncultivated NT), ballast (with ballast B, without ballast UB) and drive shaft (4WD, 2WD). After the analysis, a multistage Duncan test was used. Based on the results, overall energy efficiency of treatments included minimum amount of 9.7% associated with cultivated land treatment-two drive shafts, without ballast and maximum amount of 14.2% associated with uncultivated land-4 drive shafts with ballast. Minimum and maximum of rear wheels slip 17.2% and 40.17%, respectively, were associated with four drive shafts with ballast and two drive shafts without ballast. Minimum fuel consumption was determined 22.02 liter per hectare in four drive shafts without ballast. Studying the effect of ballast factors and shafts on overall energy efficiency and average rear wheels slip percentage in both conditions was significant in 1%, while fuel consumption per hectare was not significant.
