Comparative Study of Chisel Plough Types and Their Effect on Some Performance Characteristics

Abstract This article aims to compare the performance of two types of chisel ploughs as well as study the influence of shank types on indicators, average fuel consumption, slip percentage, field efficiency, plough shank vibration, and noise in the tractor driver’s environment. The experiment included three factors: the first one was plough shank type (rigid or flexible), and the second factor was two driving speeds (4.5 and 7.7 km·h −1 ), while the third factor was two tillage depths (10 and 20 cm). The greatest effect of tractor driving speed was observed during acceleration, resulting in increased slippage by 26.39%, plough shank vibration by 17.42 m·s −2 , and noise around the driver by 94.61 dB, with a reduction of fuel consumption by 15.87 l·ha −1 and field efficiency by 61.94%. The results showed that the plough with the flexible shank outperformed compared to the rigid shank by having less fuel consumption 19.56 l·ha −1 and slip of 17.31%, as well as the best field efficiency of 70.06% with a unique shank vibration of 22.63 m·s −2 and the lowest noise emission around the driver 89.77 dB. The high speed of the flexible shank has a positive effect on fuel consumption 14.20 l·ha −1 and shank vibrations 27.81 m·s −2 .
