A field guidance system is required to keep field equipment operating only on the predetermined paths. Ridging can be fully implemented with an automatic guidance system for agricultural vehicles. An experiment was carried out in the farm of Kenana Sugarcane Company in November 2019. The objective was to study the effect of speed on the performance of Tractor with Ridger by using automatic steering under field conditions. A Case Tractor was equipped with Auto-guidance system (Trimble receiver). The treatments consisted of three forward speeds (6.5, 8.5 and 10 km/h). The experiment was laid out in a complete randomized block design (CRBD) with three replications. The cross-track error (cm) was determined to investigate the precision and accuracy of the auto-guidance system. Performance variables namely effective field capacity (ha/h), field efficiency (%) and fuel consumption (l/h) were also calculated. The results of the analysis showed that the cross-track error, effective field capacity and fuel consumption were significantly affected by tractor forward speeds. Increasing of operating speed from 6.5 km/h to 8.5 km/h then to 10 km/h led to increase in the cross-track error from 4.67 to 5.33 to 6.2 cm, respectively, effective field capacity from 3.9 to 5.1 to 6 ha/h, respectively, and fuel consumption from 3.13 to 4.27 to 5.17 l/h, respectively. In contrast, the field efficiency was not significantly affected by the tractor forward speeds. Furthermore, it decreased by increase of tractor forward speed from 6.5 km/h to 10 km/h. It can be concluded that the tractor forward speed was the major factor affecting the steering accuracy.
