Title: Effect of Forward Speed on Tractor Performance under Clay Loam Soil
Author: Mohammed, Tewheeda Abdelhameed Fareed
Abstract: This study was conducted at the demonstration farm of the Faculty of Agriculture s- University of Khartoum during October and November 2013 to investigate the effect of three tractor forward speeds (4, 5 and 6 km/h) on the performance of an agricultural tractor (field capacity, field efficiency, fuel consumption, depth of ploughing and rear wheel slippage). Tractor performance was carried out under a three bottom disc plough. The experiment was arranged in a completely randomized block design with three replicates. High value of field capacity (0.65 fed/h) was recorded for the speeds 5 and 6 km/h, while the lowest speed 4 km/h recorded the lowest value of field capacity (0.55 fed/h). High efficiency (82.7 %) was obtained when the speed was 4 km/h followed by 78.7 % for the speed of 5 km/h, whereas speed 6 km/h recorded the lowest efficiency (74 %). High fuel consumption (11.48 l/fed) was recorded for the speed 4 km/h, followed by 10.89 and 8.40 l/fed for the speeds 5 and 6 km/h, respectively. Both speeds 5 and 6 km/h gave high values of depth of cut (23.3 and 22.7 cm, respectively) as compared to a low value of 20.7 cm for the speed 4 km/h. The results also showed that high slippage (9 %) was recorded for the speed 4 km/h as compared to 8.8 % and 8 % under the speeds 5 and 6 km/h, respectively. It is recommended that the speed 6 km/h is the most appropriate for ploughing with the disc plough as it gives high field capacity, low fuel consumption and low value of tractor rear wheel slippage.
