Abstract
A field experiment was conducted during Winter Season 2022- 2023. The aim of experimental to evaluate the effect of tractor engine speeds and gear position on the vibration levels during sowing operation. The first factor was engine speed of tractor (1000, 1500 and 2000 rpm) and the second factor was the third gear position at two level high and low speed. The measurements were taken at three separate locations (platform, seat and steering wheel) of tractor, in three direction (vertical, horizontal and lateral). The experimental laid out using randomized complete block design (RCBD) with three replications. The results of this study indicated that vibration level was increased as the engine speed of tractor increased at platform, seat and steering wheel in all directions. The change in the gear position setting has a significant effect on the vibration level. The lowest value of vibration acceleration (2.633m.s-2) was obtained at low speed. The maximum acceleration level (9.472m.s-2) was achieved at lateral direction in steering wheel location whereas, the minimum value (1.100m.s-2) was obtained at 1000 engine speed and low gear position in horizontal direction in seat location.
