Vibration Evaluation of the Driver’s Seat of MF 285 Tractor in Conducting the Tillage Operations

The purpose of this study was to investigate the effect of the tractor speed on the tractors’ seat vibration and to assess the level of comfort of the driver during the agricultural operation using moldboard and disc plows. Experiments were conducted on sandy loamy soil in a factorial experiment based on randomized complete block design with three replications. The effect of the type of tillage implement using the moldboard and disc plows, the velocity of advance in four levels of 4.5, 6 and 8.8 km/h and vibration was measured and evaluated at three directions of longitudinal (x), lateral (y) and vertical (z). The results of analysis of variance showed that the main effects of type of tillage implement, velocity and vibration direction on the acceleration values entered into the driver\u27s seat were significant at 1% probability level. With increasing forward velocity of the tractor-implement system the vibration on driver’s seat increased. In order to reduce the possibility of less daily vibration, it is suggested that a moldboard plow be used at a forward speed of 4.5 km/h and a disc driven at a speed of 6 km/h
