Straight-Line Accuracy of an Autopilot Tractor at Various Speeds: A Preliminary Assessment on Malaysia’s Flat Terrain
Publication Date : 20/06/2019
Nowadays autopilot mode become one of the alternative modes in driving tractor besides manual and unmanned or autonomous. Although the system has been successfully introduced in its country of origin, however, specialized assessments of this system on the areas which are different from its country of origin are prime interest to be investigated whether it suits a local terrain condition of any country. Thus, a preliminary assessment of the straight-line accuracy of autopilot tractor running at various specified levels of speed was conducted in order to understand its suitability with Malaysia’s terrain conditions. In this study, a New Holland TD5.75 tractor equipped with Trimble® EZ-Pilot® Steering System and Trimble® FmX® Plus Application was trialed on flat terrains that were overgrown with grasses at the UiTM farm in Jasin, Melaka, Malaysia. Three levels of autopilot tractor forward speeds, i.e. 1000 rpm, 1500 rpm, 2000 rpm were selected as the parameters in measuring straight-line accuracy of the tractor. The SPSS ver. 25 and spreadsheet software were used to analyze the collected data. This study found that there is a significant different between straight-line accuracy of each the tested speeds. It also showed that there is a relationship between the tested speeds and straight-line accuracy.
